Application Form Approval to import or manufacture a pesticide
Completing this application form
1. This form has been approved under section 28 of the Hazardous Substances and New Organisms
(HSNO) Act 1996. It only covers the import or manufacture of pesticides to be released in New
Zealand under section 28 of the HSNO Act. If you wish to make an application for another type of
substance (such as a veterinary medicine or industrial chemical) or for another type of application
(such as emergency, special emergency or containment), a different form will have to be used. All
forms are available on our website.
2. It is recommended that you contact an Applications Advisor at the Environmental Protection
Authority (EPA) as early in the application process as possible. An Applications Advisor can assist
you with any questions you have during the preparation of your application including advising on
any consultation requirements.
3. Before submitting this application, you may make an informal Status of Substance (SOS) advice
request to the EPA. Further information on this process is available on our website. Please note
that this is not mandatory and an SOS request is only informal advice.
4. This application form may be used to seek approvals for more than one hazardous substance, if
the substances and their uses are of a similar nature.
5. Please make sure that you obtain all appropriate permissions for the use of any data that you
have used or provided in this application form, if you are not the owner of such data.
6. Unless otherwise indicated, all sections of this form must be completed for the application to be
formally received and assessed. If a section is not relevant to your application, please provide a
comprehensive explanation why this does not apply. If you choose not to provide the specific
information, you will need to apply for a waiver under section 59(3)(a)(ii) of the HSNO Act. This
can be done by completing the section on the last page of this form.
7. Any extra material that does not fit in the application form must be clearly labelled, cross-
referenced, and included with the application form when it is submitted.
8. Please add extra rows or tables where needed.
9. You must sign the form (the EPA will accept electronically signed forms) and enclose the
application fee (including GST) unless you are already an approved EPA customer. To be
recognised by the EPA as an “Approved customer”, you must have submitted more than one
application per month over the preceding six months, and have no history of delay in making
payments, at the time of presenting an application.
10. Information about application fees is available on the EPA website. If you wish to claim a fee
reduction for a reduced-risk-formulated product the appropriate justification must be submitted at
the pre-lodgement stage for consideration.
11. All application communications from the EPA will be provided electronically, unless you
specifically request otherwise.

classification and use of their substance as possible to help inform the EPA’s assessment as well
as for submitters and decision-makers. We expect this information to be publicly available in the
application unless there is a genuine argument for it to be considered as commercially sensitive.
13. Commercially sensitive information may be put in a confidential appendix to this form (also
available on our website) and be identified as confidential. If you consider any information to be
commercially sensitive, please show this in the relevant section of this form providing your detailed
reasons for considering it to be commercially sensitive and cross referencing to where that
information is located in the confidential section.
14. Any information you supply to the EPA prior to formal lodgement of your application will not be
publicly released, unless it has already been made publicly available as part of the consultation
process. Following formal lodgement of your application any information in the body of this
application form and any non-confidential appendices will become publicly available.
15. Once you have formally lodged your application with the EPA, any information you have supplied to
the EPA about your application is subject to the Official Information Act 1982 (OIA). If a request is
made for the release of information that you consider to be confidential, your view will be
considered in a manner consistent with the OIA and with section 57 of the HSNO Act. You may be
required to provide further justification for your claim of confidentiality.

6. HSNO hazard classifications of the formulated substance
The information you provide here will form the basis of your substance’s HSNO classification.
Please consider each of the hazardous properties in the table below and provide information on those
properties that trigger any threshold level for your substance. Use the justification column to record the
reason for your classification. If your substance is a mixture, you can apply mixture rules to the
hazardous components of the mixture. If you do this, you will need to provide information on the
hazardous properties of each hazardous component of the mixture, and show your workings. See
Assigning A Product to an HSNO Approval on our website for more information.
Please use the following abbreviations if needed.
NA: Not Applicable – For instance when testing is technically not possible: testing for a specific
endpoint may be omitted, if it is technically not possible to conduct the study as a consequence of the
properties of the substance: eg very volatile, highly reactive or unstable substances cannot be used,
mixing of the substance with water may cause danger of fire or explosion or the radio-labelling of the
substance required in certain studies may not be possible.
ND: No Data or poor quality data (according to Klimisch criteria) – where there is a lack of data.
No: Not Classified based on actual relevant data available for the substance – the data is conclusive
and shows the threshold for classification is not triggered.

7. Risks, costs and benefits
These are the positive and adverse effects referred to in the HSNO Act. It is easier to regard risks and
costs as being adverse (or negative) and benefits as being positive. In considering risks, cost and
benefits, it is important to look at both the likelihood of occurrence (probability) and the potential
magnitude of the consequences, and to look at distribution effects (who bears the costs, benefits and
risks).
You will need to consider the effects on the environment and human health and welfare, including any
social effects.
In each section below, set out the information under the following three sub-headings:
• Costs and benefits which can be stated in monetary (dollar) terms
• Non-monetary risks and costs
• Non-monetary benefits.
You must fully complete this section, referencing supporting material. You will need to provide a
description of where the information in the application has been sourced from, e.g. from; in-house
research, independent research, technical literature, community or other consultation, and provide that
information with this application.
7.1. Identify all of the potential risks, costs and benefits of the substance(s)
Identification is the first step in assessing risks, costs and benefits. It is important to think about the source
of the risk, i.e. the way in which the risk is created (the exposure pathway), and then the consequences and
likelihood of exposure.
You should try to think as widely as possible about every potential risk, cost and benefit and give a brief
description.
IDENTIFICATION OF RISKS AND COSTS
• Physical hazards
GF-3308 is proposed to be classified as a flammable liquid of low hazard (3.1D). Under
some circumstances, e.g. presence of a sources of ignition, it may increase the fire risk.
• Human health
GF-3308 is proposed to be classified as a 6.1E (low acute toxicity), 6.3B (mildly irritating
to the skin), 6.4A (mildly irritating to the eye) and 6.9B (target organ toxicant) substance.
Human exposure to GF-3308 can occur at any stage of the product life cycle (manufacture
and packaging, importation, transport and storage, use and disposal).
• Environment
GF-3308 is highly toxic in the aquatic environment (proposed classification 9.1A). In terms
of the product life cycle, the most relevant hazard can be identified for the application of
May 2015 EPA0316
26
Application Form Approval to import or manufacture a pesticide
the substance in the field. GF-3308 is not proposed to be used for the control of any
pathogens in the aquatic environment. The only relevant exposure route for aquatic
organisms is via accidental spills or off-target movement (such as spray drift).
• Risks to society and the market economy
There are not expected to be any significant adverse impacts on the social environment
with the controlled use of GF-3308, apart from the potential health and environmental
effects discussed above. It is argued in this application that GF-3308 brings significant
benefits to the New Zealand agricultural sector.
IDENTIFICATION OF BENEFITS The following benefits have been identified for GF-3308:
• Access to a novel active ingredient for the New Zealand farmers
• Access to a state-of-the-art patented formulation for the New Zealand farmers
• Control of the key fungal disease of high economic significance
• Yield loss prevention
• New, unique mode-of-action against Septoria tritici in wheat
• A significant contribution to the future robust fungicide resistant management
strategy in wheat for New Zealand, the need for which is becoming more urgent
in the face of the reported instances of resistance in the Septoria pathogen in New
Zealand and in other wheat producing countries
• Low application rates
• Desirable toxicological and ecotoxicological profile

7.2. Provide an assessment of those risks, costs, and benefits identified in Section 7.1
This section excludes risks, costs, and benefits which relate specifically to Māori taonga or to international
agreements. See Sections 7.3 and 7.4 for those aspects.
A full assessment must be provided of all the risks, costs and benefits identified in Section 7.1.For the risk
assessment our preferred format is quantitative, however, you may also provide a qualitative assessment if
you can justify this. If you are providing your risk assessment in supporting documentation with this
application you can provide a summary of all the risks this in this section.
Please note that if you do not complete a full assessment of all risk, costs and benefits this may result in
the EPA requesting further information from you, which will mean that your application takes longer to
process.
ASSESSMENT OF RISKS AND COSTS
• Physical hazards
GF-3308 is a flammable liquid of the lowest hazard under HSNO (3.1D). For comparison,
eucalyptus oil is also classified 3.1D under HSNO. In addition to containing the HSNO
classification, the label and the SDS will state the hazard and instruct the user to avoid
sources of ignition. Given the use pattern, the low hazard and highly regulated transport,
use and storage of agrichemicals the likelihood of GF-3308 exposure to a source of ignition
is negligible and therefore the risk is low.
• Human health
There are a number of HSNO hazard classes triggered for GF-3308: the lowest level of
acute toxicity (6.1E), mild irritation to the skin (6.3B), mild irritation to the eye (6.4A)
and low target organ toxicity (6.9B), oral and inhalation. It is useful to put the hazard
classification in the context of commonplace substances carrying the same or similar
HSNO hazard classification:

Harmful to human target organs or
systems (when ingested or inhaled)
Vitamin A (6.9A (oral))
Acetic acid >80% aqueous solution
(vinegar) (6.9B (inhalation))
It should also be noted that all human health hazard classes are triggered solely by co-
formulants (fenpicoxamid does not trigger any toxicity classification). GF-3308 is a state-
of-the-art, patented emulsifiable concentrate based on a three-way organic solvent
system. Based on the understanding of how fenpicoxamid’s activity and redistribution
across the plant surface is influenced by the formulation composition, GF-3308 has been
designed to minimise fenpicoxamid application rate and optimise the product’s
performance and storage stability. The necessary excipients in GF-3308, which contribute
to its hazard classification include the following materials: a reaction mass of N,N-
Dimethyloctan-1-amide and N,N-Dimethyldecan-1-amide (no CAS number available),
cyclohexanone (CAS 108-94-1), ethoxylated tridecyl alcohol (CAS 78330-21-9),
dodecylbenzenesulfonic acid calcium salt (CAS 84989-14-0) and eo/po block copolymer
(CAS 9038-95-3).
Manufacturing, packaging and labelling may be done either overseas or in the company
owned pesticide manufacturing plant in New Plymouth or other suitable contractor facility.
The risks during manufacture are managed mainly by establishing an adequate
containment system, which prevents the escape of GF-3308, contamination of the facility,
excludes unauthorised people and unwanted organisms from the facility, prevents
unintended release of the substances, controls the effects of any accidental release,
manages waste disposal and establishes procedures to inspect and monitor the
containment facility. The potential for human exposure for people handling GF-3308 during
its manufacture, packaging and labelling is reduced to a negligible level by implementing
such a containment system coupled with the compulsory use of appropriate personal
protective equipment as well as training and qualification requirements for staff on
handling hazardous substances and following established Standard Operating Procedures.
During transport and storage of GF-3308, only one scenario can be identified for human
exposure to the substance: isolated incidents where spillage occurs. HSNO controls (the
label, SDS and packaging) and adherence to the Land Transport Rule 45001, Civil Aviation
Act 1990 and Maritime Transport Act 1994 will apply to manage those risks, which are
therefore considered negligible.
Disposal of GF-3308 is most likely to be achieved through the use as a foliar spray. Unused
product and packaging will be acceptable for collection by Agrecovery, the Rural Recycling

Programme, which is an industry stewardship scheme. Alternatively, empty packaging
should be crushed or punctured and buried in a suitably approved landfill. The end users
disposing of the substance will have the necessary knowledge (e.g. via information
provided on the label and SDS) to manage the risk adequately.
The most relevant exposure scenario is identified for the end users of GF-3308, who handle
and apply the product on farm. Each triggered hazard class will be discussed separately in
the following paragraphs.
Acute toxicity (6.1E) GF-3308 has been classified as 6.1E based on the data available for a closely similar
formulation, a study conducted in compliance with the OECD 423 guideline. The acute oral
median lethal dose (LD50) for a closely similar substance in Wistar rats was found to be
between 2,000 and 5,000 mg/kg body weight. This is equivalent to 140 - 350 g
(approximately 138 – 344 mL) of GF-3308 for a person weighing 70 kg. The likelihood of
a person ingesting a fraction of this amount through normal use is improbable. To reduce
the risk of any incidental ingestion, the label will also contain standard precautions: DO
NOT eat, drink or smoke while using. Avoid inhalation of product or spray mist. Remove
protective clothing immediately after handling this product and wash hands and face before
meals and after work.
Eye and skin irritation (6.3B and 6.4A) GF-3308 has been classified as 6.3B based on the data available for a closely similar
formulation, a study conducted in compliance with the OECD 404 guideline. Very slight to
well-defined erythema and very slight oedema were observed in the exposed rabbits. The
mean dermal irritation scores at 24, 48 and 72 h post-patch removal were 2.00, 2.00, 2.00
for erythema and 1.00, 1.00, 1.00 for oedema for the three tested rabbits respectively.
Recovery was complete in all rabbits by day 7 post patch removal.
GF-3308 has been classified as 6.4A based on the data available for a closely similar
formulation, a study conducted in compliance with the OECD 405 guideline. Corneal
opacity, conjunctival redness and conjunctival chemosis were observed in the tested
rabbits. The mean of the eye irritation scores observed at 24, 48 and 72 h post instillation
were 0.67, 1.00, 1.00 for corneal opacity, 0.00, 0.00, 0.00 for area of corneal opacity,
0.00, 0.00, 0.00 for iris effects, 2.00, 2.00, 2.00 for conjunctival redness, 1.00, 1.00, 1.00
for conjunctival chemosis and 0.00, 0.00, 0.00 for discharge for the three rabbits
respectively. Recovery for all symptoms in all rabbits occurred by day 7.
To manage the risk of skin and eye irritation, appropriate (and standard) statement will be
added to the product label: Causes mild skin irritation and eye irritation. Avoid contact with
the skin and eyes. When opening the container, preparing the product for use and applying
May 2015 EPA0316
30
Application Form Approval to import or manufacture a pesticide
the product, wear eye protection, cotton overalls buttoned to the neck and wrist (or
equivalent clothing) and chemical resistant gloves.
These recommendations are consistent with good practice and existing industry standards.
With such measures in place the risk of skin and eye irritation is low.
Target organ toxicity (6.9B) GF-3308 has been classified as 6.9B based on mixture rules. Two co-formulants, a reaction
mass of N,N-Dimethyloctan-1-amide and N,N-Dimethyldecan-1-amide and eo/po block
copolymer (CAS 9038-95-3) are classified 6.9B (oral) and 6.9B (inhalation) respectively.
Adverse effects from ingesting GF-3308 are only likely to occur if undiluted GF-3308 is
consumed for prolonged periods of time at high doses, which is improbable through the
normal use. Eo/po block copolymer is present in GF-3308 at a concentration <5% and will
be further diluted, in the tank mix at least 25 times (up to 200 times) therefore the
exposure through inhaling the spray mist is very low.
To manage the risks, the same measures as for acute oral classification apply. To address
the inhalation risk the label will contain the following statement: Avoid inhalation of product
or spray mist. This is good practice regardless of the agrichemical product classification
and is part of the established industry standards.
The dietary risk assessment for consumers is out of scope of the EPA evaluation, other
than setting the TELs, however, for completeness it is noted that exposure through the
diet will be evaluated by the Ministry of Primary Industries based on the comprehensive
residue dossier. Under the Food Act Dow AgroSciences has proposed a domestic MRL
(Maximum Residue Level) of 0.2 mg/kg fenpicoxamid in wheat grain (it will be 0.6 mg/kg
in the EU). This value is based on the highest residue level (0.13 mg/kg fenpicoxamid)
found in any grain sample tested after the most intensive label treatment was applied to
wheat in New Zealand (2 applications at the max proposed label rate (100 g a.i./ha), at
the latest application timing (GS69) and with the shortest allowed application interval (2
weeks)).
The EFSA set the Acceptable Daily Intake (ADI) (the amount that can be ingested on a
daily basis over a lifetime without an appreciable health risk) at 0.05 mg/kg fenpicoxamid
and the Acute Reference Dose (ARfD) (the amount that can be ingested over a short period
of time, usually during one meal or one day, without an appreciable health risk) at
1.8 mg/kg fenpicoxamid. These values are based on the lowest toxicity endpoints and
include a safety factor of 100. Assuming the highest allowed fenpicoxamid residue in grain
(i.e. the proposed MRL of 0.2 mg/kg), ADI and ARfD correspond to 250 g and 9 kg of wheat
grain respectively (this also assumes no residue decay through storage or preparation).
May 2015 EPA0316
31
Application Form Approval to import or manufacture a pesticide
Please also note that an MRL represents an exaggerated worst case scenario. The residue
found in wheat grain in New Zealand trials resulting from the most intensive label use
pattern ranged from <LOQ (limit of quantification) to 0.13 mg/kg fenpicoxamid.
The Joint FAO/WHO Meeting on Pesticide Residues established the same ADI and no ARfD
due to low toxicity. Dow AgroSciences expects the NZ EPA to establish the ADE (Acceptable Daily Exposure)
value in line with the European and JMPR ADI. Considering all the above points, the risk to human health from the controlled use of GF-
3308 is therefore considered low.
• Environment
The only environmental hazard associated with GF-3308 and triggered by the active
ingredient is its high aquatic toxicity. The formulation endpoints supporting the 9.1A
classification are the LC50 of 0.078 mg/L in rainbow trout (from a study conducted
according to the OECD 203 guideline) and the EC50 of 0.048 mg/L for Daphnia (from a
study conducted according to the OECD 202 guideline). For comparison, copper hydroxide,
a fungicide certified for use in organic fruit and vegetables, is also classified 9.1A based on
the endpoints of LC50 of 0.023 mg/L in fathead minnow and LC50 of 0.0065 mg/L in
Daphnia6. The registered minimum application rate of copper hydroxide in stone fruit for
example is 1.9 kg/ha7; no maximum rate is stated nor prescribed by the EPA controls (see
HSR000739 approval).
Laboratory and field studies have been conducted to determine the fate of fenpicoxamid
in the environment. Fenpicoxamid degrades rapidly in the environment to UK-2A8 which
then degrades rapidly to pesticidally non-active compounds (the laboratory hydrolysis DT50
for fenpicoxamid at pH 7 is 0.9 days, the laboratory photolysis DT50 for fenpicoxamid at
pH 7 is 3.1 days, soil aerobic laboratory DT50 is 1.9 days for fenpicoxamid and 2.3 days for
UK-2A). Dissipation of Inatreq occurs primarily through microbial degradation in the soil
and hydrolysis and photolysis in water. Laboratory studies have demonstrated an average
Koc of 53,173 mL/g for fenpicoxamid and 10,040 mL/g for UK-2A indicating that they are
strongly adsorbed to soil.
6 EPA’s Chemical Classification and Information Database (CCID) 7 Refer to HORTCARE Copper Hydroxide 300 label (ACVM registration number P008704) or ChampION++ label (ACVM registration number P009228). 8 UK-2A is a natural substance produced by fermentation of Actinomyces bacteria isolated from a soil sample. Fenpicoxamid is manufactured from UK-2A through a single post-fermentation manufacturing step. See the Benefits section for more information.

Application Form Approval to import or manufacture a pesticide
Manufacturing, packaging and labelling may be done either overseas or in the company
owned pesticide manufacturing plant in New Plymouth or other suitable contractor facility.
The risks during manufacture are managed mainly by establishing an adequate
containment system, which prevents the escape of GF-3308, contamination of the facility,
excludes unauthorised people and unwanted organisms from the facility, prevents
unintended release of the substances, controls the effects of any accidental release,
manages waste disposal and establishes procedures to inspect and monitor the
containment facility. The risk of contamination of waterways, groundwater, soil or
neighbouring properties is negligible with such a containment system in place.
During transport and storage of GF-3308, only one scenario can be identified for
environmental exposure to the substance: isolated incidents where spillage occurs. HSNO
controls (the label, SDS and packaging) and adherence to the Land Transport Rule 45001,
Civil Aviation Act 1990 and Maritime Transport Act 1994 will apply to manage those risks,
which are therefore considered negligible.
Disposal of GF-3308 is most likely to be achieved through the use as a foliar spray. Unused
product and packaging will be acceptable for collection by Agrecovery, the Rural Recycling
Programme, which is an industry stewardship scheme. Alternatively, the empty packaging
should be crushed or punctured and buried in a suitably approved landfill. The draft label
contains the following statements: Dispose of equipment cleaning water onto ground away
from edible crops. DO NOT dispose of this product, spray mix or equipment cleaning water
down drains or sewers. Cleaning water should be discharged onto a designated disposal
area, or onto unused land away from desirable plants and water sources. The end users
disposing of the substance will have the necessary knowledge (e.g. via information
provided on the label and SDS) to manage the risk adequately.
The highest risk for a water body contamination is associated with the application of GF-
3308 in the field. The label will prohibit uses directly into or onto water and a corresponding
HSNO control is expected to be imposed. The draft label contains the following statements:
Very toxic to aquatic organisms. DO NOT apply directly into or onto water. No person may
apply the substance in a manner that results in adverse effects to a water body.
The most likely exposure route would be via accidental spills or off-target movement such
as spray drift.
Spray drift For any substance applied as a spray treatment, the potential for off-target drift will always
be present. Off-target drift can be minimised using drift reduction techniques. The most
common of these include:
May 2015 EPA0316
33
Application Form Approval to import or manufacture a pesticide
a) Specifying acceptable wind speed: Best practice advice is to spray only when the
wind is between 3 and 20 km/h, but for some types of products the upper limit
may be reduced. Spraying in calm conditions is not recommended as the direction
of the drift can be unpredictable in apparently still air.
GF-3308 draft label contains the following statement: DO NOT apply when wind
speeds are less than 3 km/h or more than 20 km/h as measured at the application
site.
b) Avoiding application during inversion conditions. These occur mainly at night or
early morning.
GF-3308 draft label contains the following statement: Avoid strong winds or
inversion conditions that may result in drift from the target area. Techniques to
minimise drift should be employed at all times.
c) Specifying the spray quality in accordance with ASAE (S-572) or BCPC
specifications. Higher quality (very coarse to extra coarse) spray reduces drift, but
may negatively impact efficacy for some products.
GF-3308 will be recommended to be applied with a medium quality spray in
alignment with other registered cereal fungicides.
d) Limiting the application rates.
The maximum label application rate is 2 L/ha (100 g a.i./ha). Specifying the minimum downwind buffer zones is the most common risk mitigation
measure to manage spray drift. In case of GF-3308, the risk to aquatic organisms having
the lowest endpoints, will determine the necessary buffer zones (if any). The EPA does not
publish their risk assessment methodology in sufficient detail for Dow AgroSciences to
predict the buffer zone calculations. We await the Staff Report to add mandatory buffer
zones, if applicable, to the product label as per the corresponding HSNO control.
It is appropriate that EPA use the same modelling input parameters, such as equipment
configuration (e.g. boom length, number of nozzles, release height, etc.) or climatic
conditions as for GF-2687, also a foliar plant protection product for use in cereals and

The safety of aerial applications is an area of particular, and in our view undue, concern.

required to achieve a significant level of understanding of the risks involved. The following

an as-required basis.
The majority of agricultural pilots are ‘grown’ from within the industry. The normal
career pattern is to start as a trainee loader/driver where chemical handling is learned
under supervision then an Agrichemical Handlers Certification is gained on completion of a course once sufficient experience is gained. This handlers’ certificate and
demonstrated experience is a prerequisite to complete the Pilot Chemical Rating. Once
the person has demonstrated the right ‘fit’ for the industry they will undergo pilot
training followed by Grade 2 then Grade 1 qualification. The whole process takes a
number of years and there are only 2-3 new pilots entering the industry each year.
The practices of the aerial industry have markedly improved over the last two decades due
to the introduction of rigorous protocols for the site-specific risk assessment that any aerial
applicator has to undertake and document. Unfortunately, there is no comprehensive
database of the adverse effects resulting from aerial applications in New Zealand, however,
the New Zealand Agricultural Aviation Association were able to obtain data from the
insurance claims statistics. In the 90s there were about 25 insurance claims annually
resulting from adverse effects caused by aerial spraying. Between 2007 and 2015 such
claims have averaged at 0.6/annum and in this time there were only 2 major incidents,
neither of which resulted from spray drift. New Zealand Agricultural Aviation Association
have confirmed this trend has been sustained up to date. The aerial applicators Dow
AgroSciences spoke to argue that there is no need for any tighter regulation as they can
only be insured up to $250,000 and therefore are personally liable for significant damage
to non-target crops and one significant non-insured claim would put them out of business.
May 2015 EPA0316
36
Application Form Approval to import or manufacture a pesticide
It is possible to remain dissatisfied on the basis that this data does not stretch far enough
to provide evidence of the protection of the wider environment other than non-target crops,
however, it seems reasonable to assume that good application practice, as evidenced in
the insurance statistics, is applied equally to all non-target areas irrespective of what is
located downwind. Furthermore MPI (ACVMG) operates an adverse effect reporting scheme
in New Zealand, which should capture significant spray drift incidents. No reportable spray
drift incidents for its products have been brought to the attention of Dow AgroSciences for
at least the last 10 years. Dow AgroSciences is not aware of any data or information, as
reports of adverse effects, which would constitute evidence supporting the need to tighten
controls for aerial application.
We acknowledge the fact that the aerial application of GF-3308 will only be used
occasionally and most likely only when it is impractical to use ground equipment. However,
there can be situations when aerial spraying will be indispensable, e.g. when the ground
is too soft and muddy after heavy rainfall; in conditions, which also favour the development
of fungal diseases, and it is important to have such an option available to farmers when
needed. In recent years it seems to have become necessary to produce extensive
arguments and even specific data in support of aerial application. Dow AgroSciences does
not agree this is warranted. Aerial application is managed by its own, significantly stricter
controls (such as significantly longer buffer zones in comparison to ground application). If
through risk assessment practical risk management measures can be identified for aerial
application, there should be no reason to restrict access to such a well-established
technology in New Zealand.
ASSESSMENT OF BENEFITS Dow AgroSciences is a global, agricultural research and development agrichemical
company present in 130 countries around the world and employing more than 2000
discovery and field research scientists. We are one of a very few companies that work on
discovering innovative agricultural molecules globally.
Since its birth in the late 1930s, the synthetic agrichemical chemistry has achieved
remarkable progress through R&D investment. There is a consistent trend in developing
more target specific chemistries that are efficacious at significantly lower rates and offer
steadily improving toxicological and ecotoxicological profiles, i.e. “greener” agrichemicals.
For example, in the last six decades the vertebrate selectivity ratios of insecticides (i.e. a
relative measure of toxicity to targeted insects versus non-target vertebrates) has
increased by five orders of magnitude, when at the same time field rates dropped

results in significant loss of yield.

Speckled leaf blotch has become increasingly damaging to the New Zealand cereal
production in the last few years.

Septoria infection causes lesions on leaves, which decrease the photosynthetic area. The
leaves turn yellow and die before dropping off. When this affects the top three leaves of
the wheat plant (so-called flag leaf, flag minus 1 and flag minus 2 leaves), the plant
becomes severely malnourished and the grain yield is reduced.
Septoria pathogen overwinters as mycelium, pycnidia and pseudothecia on crop debris
(e.g. stubble) or soil. It can be spread by contact, wind or rain and has multiple infection
cycles in one season. These factors together mean that, while there is some variability in
susceptibility among different wheat varieties, all crops have the potential to be infected
in warm moist conditions.
Independent trials conducted in Canterbury in the 2017/18 season, as well as trials
conducted in many European countries, demonstrate that GF-3308 provides very high level
of control against Septoria blotch and is equal to the market standard currently registered

These results demonstrate:
• The dose response (i.e. confirm the correct rates have been selected for the label)
• Efficacy of GF-3308 alone comparable to the market standard (81.5 – 97.7% control

• Efficacy of GF-3308 with the tank mix partner comparable to the market standard

New Zealand grows the highest yielding wheat in the world (up to almost 17 t/ha11) with
an average of approximately 9 t/ha. Losses of yield due to Septoria leaf blotch have been
reported at 2 – 3 t/ha and in extreme cases, 7 t/ha. Dow AgroSciences trials in 2017/18

showed control of Septoria leaf blotch with GF-3308 increased average yield from 9.7 t/ha
in untreated plots up to 12.4 t/ha, i.e. a gain of 2.7 t/ha or an increase in yield of 27%
compared to untreated. High yields not only improve the profitability of the farm but also
extract the best value from the land allocated to agriculture. It is estimated that 43,250 ha
of wheat were grown in 2018 yielding approximately 377,150 tonnes of wheat grain12. If
the yield was reduced by 30%, extra 18,500 ha would have to be cultivated to produce
the same amount of grain.

Fenpicoxamid not only provides excellent efficacy against a common pathogen of economic
importance. One of its main benefits is its fit in a robust resistance management strategy
for cereal fungicides. This is because fenpicoxamid has a unique mode of action. It is the
12 “New Zealand survey of cereal areas and volumes: July 1, 2018” Arable Industry Marketing Initiative with Foundation for Arable Research.

first molecule in the picolinamides group of Quinone inside Inhibitor fungicides (FRAC13
mode of action group 21). Binding to complex III (the bc1 complex) at the Qi site (the
inner mitochondrial membrane), fenpicoxamid inhibits mitochondrial respiration in fungi
by blocking electron transfer in the respiratory chain. Inhibition of fungal mitochondrial
respiration results in a reduction in the amount of ATP (adenosintriphosphate) produced.
As ATP is the main chemical energy carrier that drives the vital functions of cells, the key
biochemical processes are disrupted, growth is inhibited and the fungus dies.
Fungicide treatments currently available in New Zealand include:
• Triazoles, e.g. epoxiconazole, tebuconazole, propiconazole, prothioconazole (Group
3 fungicides),
• Succinate-dehydrogenase inhibitors (SDHIs), e.g. isopyrazam, fluxapyroxad
(Group 7 fungicides) and
• Strobilurins, e.g. azoxystrobin, picoxystrobin, pyraclostrobin (Group 11 fungicides).
Development of resistance is a major concern in cereal production globally as well as in
New Zealand. While triazoles still show reasonable activity against Septoria in New
Zealand, reduced sensitivity has been widely reported13. Resistance to strobilurins, which
until recently had been the most effective in controlling Septoria, has been confirmed in
New Zealand. In Europe resistance to SDHIs is evident in the Septoria pathogen population
and this group of fungicides, while still very effective in New Zealand, is considered
moderate to high risk of resistance14. A new mode of action, which fenpicoxamid offers,
will become a crucial component of the resistance management toolbox. The need for a
robust resistance management strategy for cereal fungicides in New Zealand is universally
recognised in the industry. It will extend the lifespan of all fungicides increasing the viability
of the wheat industry. It is important to note that wheat in New Zealand is grown primarily
for animal feed. Unlike pasture or forage brassicas it can be stored for long periods of time
providing milk and meat producers with a flexible stock food. Therefore, benefits for the
wheat growers translate also into benefits for dairy, beef and lamb farmers.
While Dow AgroSciences does not agree synthetic molecules are inherently more
(eco)toxic, some users or members of the public may find fenpicoxamid’s natural origin an
important attribute. Fenpicoxamid is derived from a natural substance, UK-2A, produced
by fermentation of Actinomyces bacteria isolated from a soil sample collected at the Osaka
City University, Japan. Fenpicoxamid is synthesized from UK-2A through a single post-
fermentation chemical modification, which is required to enhance stability and performance
13 Fungicide Resistance Action Committee. FRAC is a Specialist Technical Group of CropLife International, who recommends resistance management strategies. They classify fungicides into distinctive groups based on their mode of action. A FRAC fungicide group is the most basic piece of information in any resistance management strategy, which involves alternating products with different modes of action and using other than chemical control methods. 14 The Foundation for Arable Research, “Issue 7 Cereal Disease Management (Revised 2016)”

Application Form Approval to import or manufacture a pesticide
(note, fenpicoxamid is devitalised and contains no viable microorganisms). Once in the
plant or fungal tissue, fenpicoxamid is converted back into UK-2A, its main metabolite.
GF-3308 is an emulsifiable concentrate containing 50 g/L fenpicoxamid, whose
redistribution across the plant surface is highly influenced by the formulation type. Based
on this understanding GF-3308’s performance has been optimized through specific,
patented formulation design to minimise fenpicoxamid application rate, maximise its
activity against Septoria, improve storage stability, rainfastness, ease of application and
overall product performance.
Fenpicoxamid has very low mammalian toxicity with no HSNO hazard classes triggered.
The HSNO classification for the formulated product, does not include any significant
hazards, which would require risk management measures outside of good industry
practice. Fenpicoxamid also degrades quickly in the environment and has very low toxicity
to non-target organisms with the exception of fish and aquatic crustaceans. However, with
the proposed use pattern, fenpicoxamid and GF-3308 pose low risk to the aquatic
environment.
GF-3308 is not designed to replace any existing product but complement a resistance
management strategy, however, a hazard comparison with its major competitors in the
marketplace is presented in the table below:

is expected a number of HSNO additional controls
(s77A controls) will be imposed on GF-3308 to
manage the risks to water bodies:
• The substance must not be applied onto or into
water.
• No person may apply the substance in a
manner that results in adverse effects to a

• A maximum application rate control
• A buffer zone control. Label advice will be provided to comply with EPA

The use of agricultural chemicals like GF-3308 is often
considered as negatively impacting the balance of
nature. The use of GF-3308 will be limited to
commercial wheat production where the benefits to
farmers, including Māori farmers, and the New
Zealand economy significantly outweigh the risks.
Environment Medium See cultural impacts.
Economy
No risk
The applicant is unable to identify any economic risk
resulting from the use of GF-3308. It is argued in this
application that this product will bring significant
benefits to the New Zealand cereal production and the
associated industries (e.g. dairy). Please refer to the
benefits section of this application.
Treaty
Principles
No risk
The applicant is unable to identify any pathway, by
which the Treaty Principles could be violated by the
application of GF-3308 when appropriate risk
management measures (as imposed by the HSNO
controls) are applied to minimise health,
environmental and cultural impacts.
Dow AgroSciences undertook a pre-application Māori consultation. We were grateful to be
given an opportunity to present GF-3308 to the Ngāi Tahu HSNO Komiti at one of their
meetings. Prior to the meeting an application summary was provided. Many questions were
addressed during the meeting; one regarding the choice of the test species for the
bioconcentration study was responded to via e-mail after the meeting (summarised in the
following paragraphs). No written comment was provided to Dow AgroSciences by the
Komiti.
The application summary was also distributed for input and comment by the EPA within Te
Herenga, the extensive National Māori Network. Te Herenga is a forum for kaitiaki and
environmental resource managers to come together and discuss important environmental
issues. Dow AgroSciences also reached out via personal communication to Ngāti Whātua
Ōrākei and Te Rūnanga-Ā-Iwi O Ngāpuhi, who made submissions for our previous
application in 2015, to bring the consultation to their attention. No comments were
received within the 3-week consultation period.
While no questions or comments were made in writing, Dow AgroSciences would like to
explain their position on a number of issues often raised for pesticide applications as well
May 2015 EPA0316
46
Application Form Approval to import or manufacture a pesticide
as those discussed at the Ngāi Tahu HSNO Komiti meeting and in the subsequent
communication.
Data provided to the EPA in confidence
On many previous occasions the confidential appendices have been accused of being a
“blanket concealment for any data deemed commercially sensitive”. In many cases the
applicants were criticised for withholding the formulation composition or the identity of the
impurities. Usually, such information cannot be provided as it is a trade secret. Disclosing
some composition related information can also generate commercial prejudice (e.g.
addresses of manufacturing plants, suppliers of ingredients, etc.).
A joint CropLife America and European Crop Protection Association report15 shows that the
cost of developing and registering new pest and disease prevention products (i.e. a novel
formulation containing one new active ingredient) was estimated at about 290 million USD,
with the cost of generating the toxicology and ecotoxicology component alone constituting
about 1/3 of this sum. It is understandable then that the R&D companies invest
considerable efforts in guarding the proprietary information.
However, no information is withheld from the EPA whose role is to impartially assess
the data, characterise the risks and impose controls.
Nevertheless, Dow AgroSciences understands the concerns and confusion resulting from
the unspecified contents of the confidential dossiers and therefore a general list of the
studies provided to EPA can be found in Section 6 of this application form (and more
information can be provided on request).
Also, study summaries for all submitted studies will be included in the public Staff Report.
Dow AgroSciences believes it would be better to conduct the consultation after the Staff
Report is released but the legislation places it pre-lodgement when it is impossible for the
Staff Report to be available.
Lastly, it is Dow AgroSciences’ belief that the Māori consultation is not undertaken with an
aim that the Māori conduct a comprehensive pre-submission data evaluation and risk
assessment but to identify all potential risks that will be carefully assessed by the EPA
during their evaluation, and the results of which will be published as the Staff Report. With
this in mind, Dow AgroSciences believe that sufficient information is provided.

Formulation composition undisclosed
As noted above, the formulation composition and the impurity profile for fenpicoxamid, as
well as other chemistry and manufacturing information (e.g. manufacturing methods,
addresses of manufacturing sites, etc.) are provided to the EPA in confidence and usually
constitute a trade secret.
However, since GF-3308 is protected by a US patent, the formulation design is disclosed
in the patent documentation. Section 7.2 above explains that the necessary excipients in
GF-3308, which contribute to its hazard classification include the following materials: a
reaction mass of N,N-Dimethyloctan-1-amide and N,N-Dimethyldecan-1-amide,
cyclohexanone (CAS 108-94-1), ethoxylated tridecyl alcohol (CAS 78330-21-9),
dodecylbenzenesulfonic acid calcium salt (CAS 84989-14-0) and eo/po block copolymer
(CAS 9038-95-3).
It should also be emphasised that the hazards of GF-3308 are fully disclosed and discussed,
and the HSNO classification is proposed for the substance including all of its ingredients
and their impurities. The technical grade active ingredient as well as the formulation do
not contain any other components of toxicological significance that would override the
hazards determined for the active ingredient or the formulation. In fact, the toxicity of all
of the impurities present in the active ingredient is accounted for during the testing of the
active ingredient and the formulation. Where no formulation data is available, such as for
non-acute hazards, the classification is based on mixture rules according to the EPA
Thresholds and Classifications User Guide, again taking into account all of the components
and their impurities.
Data on native species
The ecotoxicological data package has been put together according to the EPA
requirements as published on their website. There is no requirement to test any New
Zealand native species, neither are there any guidelines available on what species should
be tested and what protocols should be followed. More importantly, however, Dow
AgroSciences believe that such testing is unnecessary as the risk can be adequately
characterised based on the endpoints established for the internationally accepted indicator
species according to the internationally accepted guidelines (such as OECD, OPPTS). This
is the approach used in other countries with advanced regulatory systems. The indicator
species used in these protocols have been confirmed to be suitable based on decades of
research and are used in all countries to estimate the risk for their native species. For
regulatory purposes the species tested need to meet a number of conditions such as to be
easily cultured in laboratory conditions, have sensitivity to known toxicants and have been
demonstrated to allow derivation of repeatable/reproducible results irrespective of the test
facility. The ecotoxicological testing also employs a tiered approach, i.e. when toxicity is
May 2015 EPA0316
48
Application Form Approval to import or manufacture a pesticide
indicated in one species at trigger doses, further species have to be tested and therefore
the hazards are always adequately investigated. The OECD countries accept these tests
and consider the indicator test species used as surrogates sufficiently representative to
extrapolate to other organisms for the purposes of classification and risk assessment to
account for entire ecosystems.
The requirement to generate country specific ecotoxicological data for each hazardous
substance would add considerably to the costs of bringing new products and uses to the
very small New Zealand market, beyond what its size can support. If the costs become
prohibitive for no justifiable scientific reason, innovative products will not come to New
Zealand depriving farmers of newer, safer to use products and potentially putting them at
a competitive disadvantage in export markets. Moreover, it would be contradictory to the
global efforts to minimise vertebrate and invertebrate testing and would create an
unnecessary differentiation of New Zealand among the OECD countries, which could be
regarded as a barrier to trade.
This issue has been extensively discussed in the series of workshops EPA hosted in 2015
– 2017 and in which Dow AgroSciences participated. It is our understanding that the
consensus was reached not to introduce additional data requirements in New Zealand.
Bioconcentration factor in longfin eel
During the Māori consultation a specific question regarding the choice of the test species
was raised and we would like to include it in this discussion for the benefit of all public
submitters.
The BCF (bioconcentration factor) for fenpicoxamid is reported to be <5 L/kg. This value
comes from a GLP study in zebrafish conducted according to the OECD guideline 305. The
question was whether, or actually why no BCF factor was experimentally established in
longfin eel, which is more relevant to New Zealand.
Zebrafish was tested because it is one of the recommended species for the OECD 305 fish
BCF study and the laboratory, which ran the test has considerable experience working with
this species. Longfin eel is not a recognized OECD or US EPA fish species and Dow
AgroSciences is not aware of any reputable laboratory, which could run such a test or a
regulator, which would accept such a study to satisfy the bioconcentration data
requirement. The list of recommended species includes those that can be cultured in the
lab and the control and reference toxicant testing results meet established validity criteria,
which are not available for the eel.
Bioaccumulation potential is a function of the lipid content, which is much higher in eel
than in zebrafish so the <5 L/kg endpoint is likely to be underestimated for the eel.
However, the OECD 305 study also produces an endpoint normalized to the lipid content,
May 2015 EPA0316
49
Application Form Approval to import or manufacture a pesticide
which in the zebrafish study is reported to be <2.6 L/kg on a 5% lipid-corrected basis. This
value can be used to estimate a BCF in a species with a higher or lower lipid content. Using
the conservative value of 30% fat content for the eel (source, see p. 8), a BCF for it can
be calculated to be <15.6 L/kg. Please note that this is a non-definite endpoint (<), since
there were no detected residues in the study, and the <15.6 L/kg value has a limited
meaning.
The trigger to consider a substance bioaccumulative is >1,000 L/kg in US and >2,000 in
EU (and >5000 for very bioaccumulative in both US and EU). It is understood the NZ EPA
follows the European EFSA. Both, the measured BCF in zebrafish and the estimated BCF in
longfin eel, are very low, even if one assumes the worst case values (i.e. without the “<”).
The aquatic DT50 of fenpicoxamid is less than 24 hours. Therefore, owing to its fast
degradation in the aquatic environment and the very low BCF values, fenpicoxamid is
highly unlikely to bioaccumulate in any aquatic species.
Draft label not provided
The draft label is subject to both the pending HSNO controls and the ongoing MPI review.
These can result in important label amendments. Some sections are not even in a draft
form and await the EPA Staff Report to be released (e.g. buffer zones). We believe there
is little value in focusing the consultation on a document so far from the final. Importantly,
EPA does not review label content (while there can be HSNO additional controls dictating
some compulsory label wording). The subject of the EPA evaluation is the use pattern,
which is discussed in this form in great detail (see Section 5.1 of this application form).
Many draft label statements addressing the risks to human health and the environment
are also quoted in this form.
The detailed risk assessment
This document does not attempt to provide a comprehensive risk assessment for GF-3308.
The EPA does not publish guidelines on the risk assessment methodologies they use in
sufficient detail to allow applicants pre-empt the conclusions from the New Zealand risk
assessment. It would also be an unnecessary duplication of a substantial piece of work,
which EPA will undertake independently regardless of the level of risk assessment
presented by the applicant. The comprehensive New Zealand specific risk assessment for
GF-3308 will be published by EPA as the Staff Report.
Dow AgroSciences have made all possible efforts to provide a review of potential risks and
risk management (lifecycle controls) as comprehensive as possible and have based this
document on all the data available (and submitted to the EPA) as well as drawing from the
competent EFSA conclusions, which are publically available.

Risks to taonga species
Dow AgroSciences supports the EPA in incorporating the taonga species in its risk
assessment as long as it maintains high scientific rigour and is equally applied to all
pesticides in the New Zealand market.
Dow AgroSciences do not agree that imposing unprecedented and limiting controls on
novel, low hazard pesticides benefits the farmers or, indeed, the environment or human
health, when much higher hazard products that are already in the marketplace do not
attract the same limiting controls. The labels for new products, which are a result of a
modern, significantly more rigorous risk assessment and more stringent risk management
controls, while at the same time 30, 40 year old formulations have hardly any restrictions,
misleads the users and the general public into assuming that the older products are safer
and additionally makes them easier to use. This has the perverse outcome of users
preferentially selecting the older products with less stringent controls (but higher hazards
and risks). This coupled with the unavoidable premium associated with state-of-the-art
products stands in the way of adopting new, better technologies, tools and approaches
which benefit people, the environment and the economy.
There are about 1,500 pesticides registered for use in New Zealand. While there is no
statistics, Dow AgroSciences estimates there is less than 20 agricultural chemicals
approved with standard buffer zones and less than 10 with buffer zones for the protection
of endangered species. While we accept, it is unfeasible to roll out new methodologies and
requirements uniformly across the market, the gap between old and new in New Zealand
is truly extreme and more effort should be devoted to the implementation of new
restrictions more uniformly, in stages, allowing at least an appreciable percentage of
existing products to catch up (via reassessments) before the next level of conservatism is
imposed on novel products.
Tank mixing
In recent years some of the public submitters have raised concerns about toxic and
ecotoxic effects of tank mixes, i.e. when two or more agrichemicals are applied in one
spray treatment.
GF-3308 has sufficient efficacy to control Septoria on its own, however, to prevent the
development of resistance it will be recommended to be applied with a tank mix partner –
a suitable wheat fungicide with a different mode of action, e.g. prothioconazole.
In general, tank mixing is used in agriculture to broaden the spectrum of activity (e.g.
control both Septoria leaf blotch and powdery mildew), to prevent the development of
resistance in the target pest by targeting multiple sites, to increase the efficiency of crop
May 2015 EPA0316
51
Application Form Approval to import or manufacture a pesticide
protection treatments (one pass instead of two or more) or to apply a required combination
of actives, which are unstable in each other’s presence to allow a practical shelf life and
have to be mixed together immediately before the application.
Like in other countries, tank mixing is a standard agricultural practice in New Zealand and
a good practice too. It allows farmers to simultaneously treat multiple pests and crop
conditions in the most economical and efficient way. It reduces the time and resources
needed (water, fuel, adjuvant) as well as minimises operator exposure (which is a function
of the exposure time), vehicle emissions, soil compaction and crop injury.
The design of a spray program depends on many factors such as weeds, pests and diseases
present, environmental conditions, crop variety, farmer’s economic decisions, etc. and
therefore the sheer number of combinations would be unfeasible to evaluate.
The NZ EPA approves individual substances. Any tank mix partner will have its own HSNO
approval and controls. The users must ensure compliance with the strictest controls
applicable to any substances in the tank mix. If an aquatic buffer zone for a product A is
20 m and for a product B it is 50 m, a 50 m buffer zone applies to the A+B tank mix; if
the withholding period for a product A is 3 weeks and for a product B it is 1 week, the
withholding period for the A+B tank mix is 3 weeks and so on. If there are multiple products
applied at the same time, the applicator may have to navigate a long list of restrictions.
However, adding tank mix specific recommendations on all labels would hardly reduce this
complexity.
It is acknowledged that there may be some uncertainty with respect to
synergistic/antagonistic effects, additive toxicity or the “cocktail” effect. However, true
synergy is rare. Additive toxicity can be suspected when multiple chemicals with the same
mode of action are used. For tank mixtures usually one component, which drives the
toxicity can be identified. In such cases considering mixture effects does not result in
markedly stricter mitigation measures than considering the driver alone. The benefit of
such minor potential distinctions is not outweighed by the drastically increased complexity
of labels or in the risk assessment.
While no single tank mix partner can be nominated for GF-3308, prothioconazole is named
as an example of a suitable candidate. Fenpicoxamid, a quinone inside inhibitor, and
prothioconazole, a demethylation inhibitor, have different modes of action, which is the
whole point of a resistance management strategy. While mixtures of GF-3308 with a
prothioconazole product did show a slightly improved efficacy in our trials, the primary
purpose of tank mixing GF-3308 with prothioconazole is not the increased activity but
targeting two distinctive sites in the fungus cell simultaneously. Genetic mutations leading
to the development of resistance against both modes of action at the same time are
significantly less likely than to each one separately and therefore the risk of resistance
May 2015 EPA0316
52
Application Form Approval to import or manufacture a pesticide
development to either mode of action is significantly reduced. This way the future viability
of both fenpicoxamid and its tank mix partner is safeguarded.
With two different modes of action, the consideration of additive toxicity is not appropriate.
Dow AgroSciences is also not aware of any data showing synergy between fenpicoxamid
and prothioconazole (or any other triazole, SDHI or strobilurin).
The only proposed ecotoxicological hazard classification for GF-3308 is its aquatic toxicity,
9.1A. Prothioconazole products are classified either 9.1B (HSR101175, HSR101177,
HSR001661) or 9.1C (HSR101126). While, the endpoints, on the basis of which these
classifications were applied to prothioconazole products is not published on the EPA
website, the range to trigger a 9.1B classification is >1 but ≤10 mg/L and for the 9.1C
classification it is >10 but ≤100 mg/L (the endpoint for GF-3308 is 0.048 mg/L in Daphnia
and 0.078 mg/L in rainbow trout). Clearly, the aquatic toxicity will be driven by
fenpicoxamid, not prothioconazole. Therefore, any HSNO controls for GF-3308, like an
aquatic buffer zone, will be protective against prothioconazole.
Through technical training materials and user guides Dow AgroSciences will recommend
similar resistance management strategy as well as spectrum extension approach where
needed for fenpicoxamid in Europe. This does not trigger the tank mix evaluation under
the EU regulations.
While in some jurisdictions under specific circumstances tank mixing triggers additional
toxicological and ecotoxicological risk assessment, which is usually based on concentration
addition models to estimate mixture endpoints, Dow AgroSciences New Zealand is not
aware of any regulator who would apply these in the case presented here. Regulation has
its limits and it is globally recognised it is impossible to account for every possible scenario
in the field. In our opinion it would also be impossible to demonstrate that allocation of
resources in such a pursuit to account for as many scenarios as technically feasible, can
be justified.
