Introduction to Integrated Pest Management

Daniel Banks, Next Generation IPM

Defining IPM •  Many definitions are used.

•  Simply put, a proactive and multifaceted approach to pest management that is grounded in applied ecology.

•  Demands a robust understanding of the biology of your crop, its pests/diseases, and how both are influenced by the environment.

Cannabis Specific Considerations •  Unique crop and unique cultivation environments

•  Viable control strategies vary dramatically with crop age

•  In many cases traditional action thresholds don’t translate well

•  Compliance is Key

Components of a Cannabis IPM Program Pest Monitoring/Identification

Control Strategies:

Structural/Environmental Controls

Resistant Varieties

Cultural Practices

Biological Controls

Compliant and Responsible Pesticide Use

Responsible Pesticide Selection and Use •  Understand the different types of pesticides available in your market and how to

use them compliantly.

•  Use products, techniques, and strategies that maximize damage to pests while minimizing risk to your crop, your employees, your consumers, and the environment.

Pesticide Use and Cannabis Testing •  Look to your State’s Department of Agriculture, Department of Health, and

Cannabis enforcement body for State specific testing regulations.

•  Understand how pesticide use can influence your test results.

•  Understand how testing regulations differ between State markets and adapt your pest management techniques to fit your State’s standards.

Evolution of Pesticide Use and Misuse

Prior to 2015

•  Questions – what can I use?

•  No resources to dedicate a focused effort on outreach or inspections

•  2012 first complaint, disgruntled employee,

violations found, CDO (WPS, Azamax, Avid and Floramite)

February 2015

•  Denver fire magazine article prompts a

discussion

•  Denver Fire, DEH, communicate visual

observations and concerns for safety regarding pesticides

•  March 2015 first formal complaints filed

Rules Established

•  PAA Rule effective March 30, 2016 – Broad label language – Tolerance exempt a.i. – Express food uses – A.I. has allowed uses on tobacco

•  25(b) w/express food uses •  Approved 24(c) •  Broad authority to prohibit use of products •  Nov 2017 – Pesticide Act Rule update

Complaints Investigated •  Pesticide Misuse Investigations Filed

–  FY 15 15 MJ –  FY 16 102 MJ 1 Hemp 56 CA –  FY 17 27 MJ 52 CA –  FY 18 11 MJ 24 CA

•  MJ complaints resolved –  FY 16 69 MJ 11 CA –  FY 17 56 MJ 1 Hemp 24 CA –  FY 18 4 MJ 18 CA

58.6% resolved resulted in an Enforcement Action.

What Did We Find? FY 16

SamplesTested: 599

Non-detectSamples: 208 35%

16% of the samples had detects of pesticides but these pesticides were not a violation to use

What Did We Find? FY 17

Adulterated Products •  Mighty Wash - Pyrethrin •  25(b) - Guardian Mite Spray

– Oregon and Colorado confirmed presence of Abamectin

•  Azatrol – 6/2017 - Oregon detected Permethrin,

Bifenthrin, Cypermethrin, Cyfluthrin, Chlorpyrifos, Malathion

– VDA running Colorado formulation samples •  Violations of the PAA vs. Public Health

Concerns

Future Issues and Approaches •  SLN 24(c) registrations

– 6/2017 EPA denied CA, NV, VT, WA – Research and Demonstration – CDA Pesticide Act Rule limited use registration

update for R&D

•  Use below labeled rates to avoid detection – CDA finding residues below LOQ, but above

MDL – Pest resistance concerns

Future Issues and Approaches

•  MED required sampling – Screening for 13 products – CDA will continue screening for 90+

•  Compliance verification – CDA will be inspecting and sampling entities

previously found in violation – WPS inspections – random sampling –  Initial CVIs showing continued misuse

Future Issues and Approaches

•  Communication of positive results – MED – CDPHE / DeH / other

•  Case workload prioritization – Dependent on personnel (June 2018) – MJ vs. conventional case workload

Integrated Pest Management From a Laboratory Perspective

Seth Wong – President TEQ Analytical Laboratories

What is Integrated Pest Management? •  Knowing and Identifying known pests

•  Unknowns

•  Operations, Procedures, and Best Practices

•  Facilities Control and Monitoring

•  Laboratory Testing Analysis

What do we know - What don’t we know •  Usual Suspects

•  What we are testing for?

•  Contaminants from other sources?

•  What we don’t know can hurt us.

Facility Operations, Procedures, and Best Practices •  Cleaning and Sanitation Regiment

•  Rotating Cleaners and active ingredients

•  Facility Controls and Environmental Monitoring

•  Tracking and Data

Laboratory Testing and Analysis •  Air Testing

•  Environmental Swabs and Sponges

•  Water Analysis
