See the latest schedule at www.wffvc2018.info
Seven years after its passage, the portion of the Food Safety Modernization Act that applies to
produce finally goes into effect, the first compliance dates for produce growers are finally within sight. The Produce Safety Rule, the portion of the Food Safety Modernization Act that directly impacts fruit and vegetable growers, requires full compliance for the largest growers effective January 26, 2018. Other growers covered by the rule will see compliance dates of January 26, 2019, and January 26, 2020, depending on the size of the operation.
Will my farm be impacted?Many fruit and vegetable farms will be impacted by at least part of the FSMA Produce Safety Rule, even those farm operations that are very small. Farms that are completely exempt from the Produce Safety Rule include those that do not grow, harvest, pack, or hold produce on your farm; or those that have average annual sales of produce of $25,000 (based on year the regulation was passed; all values mentioned must be adjusted for inflation to obtain
appropriate value for the current year, found here: https://www.fda.gov/food/guidanceregulation/fsma/ucm554484.htm) or less per year, averaged over the last 3 years.
In addition, specific produce grown, harvested, packed, or held on your farm may not be covered by the Produce Safety Rule if any of the following apply:
• The produce is a commodity that the FDA has identified as rarely consumed raw;
• The produce is for personal/on-farm consumption; or
• The produce is intended for commercial processing that adequately reduces pathogens, such as commercial processing with a “kill step” (as long as certain disclosures are made and written assurances are received, with appropriate documentation).
It is important to note the difference in the above examples; the first describes situations in which farms are exempt from the Produce Safety Rule; the second describe circumstances where
specific produce crops may not be covered by the regulation. There may be situations where a given farm is only growing produce not covered by the regulation, and others where the farm is growing a combination of produce that is covered and not covered. In each of these situations, the farm must still be in compliance with the regulations of the Produce Safety rule as applicable.
Finally, your farm may be eligible for a qualified exemption if BOTH of the following conditions apply:
• Your average annual food sales (not just produce sales) are less than $500,000 per year over the last 3 years; AND
• The majority of your food sales are to “qualified end users” – including either the consumer of the food or a restaurant or retail food establishment located in the same state or within 275 miles of the farm.
While this is not full exemption from the rules, if you are eligible for a qualified exemption, you will be subject to less extensive, modified requirements

BY DR. ERIN SILVA, ASSISTANT PROFESSOR, UW-DEPARTMENT OF PLANT PATHOLOGY
under the Produce Rule (also referred to as “qualified exempt”). There are three primary conditions that a produce operation must adhere to (in addition to the eligibility requirements listed above) to maintain their eligibility for these modified requirements:
• Provide the name and complete address of the farm where the produce was grown on either a food packaging label, sign, or document at the point of purchase;
• Comply with the compliance and enforcement requirements of the Produce Rule; and
• Be subject to the provisions regarding the withdrawal of your status as a partially covered (“qualified exempt”) operation (That is, FDA reserves the ability to revoke your “qualified exempt” status in certain circumstances).
• Qualified exempt operations are required to document that they have conducted an annual review of their eligibility for the qualified exemption.
To help determine whether your farm operation is covered under this new rule, Purple Pitchfork, in partnership with UW-Extension, has created a decision tool, which is posted on the UW Produce Food Safety Website (http://labs.russell.wisc.edu/farmfoodsafety/). This tool will help you determine if you fall into the qualified exempt category for FSMA.
Compliance DatesCompliance dates for covered activities are based on sales of produce (and must be adjusted for inflation):
• Very small farms: Greater than $25,000 but less than $250,000 in annual average produce sales in the preceding three years; compliance start date January 27, 2020.
• Small farms: Greater than $250,000 but less than $500,000 in annual average produce sales in the
preceding three years; compliance start date January 28, 2019.
• Large farms: Greater than $500,000 in annual average produce sales in the preceding three years; compliance start date January 26, 2018.
Compliance dates for the water quality standards have been extended; we currently expect the compliance dates for the water quality standards to be four years after the general compliance dates cited above. The FDA is exploring alternative standards for the agricultural water requirements established by FSMA after receiving feedback from stakeholders.
FSMA Produce Safety Rule Grower TrainingsOne of the first steps to bring vegetable farms in compliance with FSMA is for one representative from the farm to attend an FDA-sanctioned Produce Safety training workshop. Part §112.22(c) of the Produce Safety Rule requires that ‘At least one supervisor or responsible party for your farm must have successfully completed food safety training at least equivalent to that received under standardized curriculum recognized as adequate by the Food and Drug Administration.’
As of now, the Produce Safety Alliance training is the only standardized national training program recognized by FDA to prepare produce operations in meeting the regulatory requirements in FSMA Produce Safety Rule. This eight-hour, one-day Grower Training Course will cover key areas and requirements of the Produce Safety Rule including:
1. Introduction to Produce Safety
2. Worker Health, Hygiene, and Training
3. Soil Amendments
4. Wildlife, Domesticated Animals, and Land Use
5. Agricultural Water
6. Postharvest Handling and Sanitation
7. How to Develop a Farm Food Safety Plan (not required by the rule, but covered by the training)
Several PSA trainings are being scheduled across the upper Midwest to meet farmer needs. Wisconsin will be holding its first training on January 21, 2018 from 8 am – 5 pm; prior to the Wisconsin Fresh Fruit and Vegetable Conference in Wisconsin Dells, WI. Cost for the program will be $50. People interested in registering for the program can register on the WFFVC registration form in this magazine (registration will be capped at 50 participants). Additionally, several trainings will be held across Iowa (complete list of trainings can be found at https://www.extension.iastate.edu/article/produce-safety-alliance-grower-trainings-scheduled-fall-2017-winter-2018) and Minnesota (Jan 17, 2018 in St. Cloud, and on March 20, 2018 in Monticello, MN; http:/safety.cfans.umn.edu). Costs for workshops may vary depending on the amount of grant funds available to offset the costs to the participants. Documented attendance to a training must be accomplished by the compliance dates listed above; more grower trainings will be offered in coming years.
Completing the PSA training program will provide further information regarding what your farm will need to do to ensure compliance with FSMA – so, although depending on your farm size, your compliance date may be a couple years down the road, attending a training sooner than later will help you understand which records and practices your farm will need to adopt in order to ensure compliance to all aspects of the Produce Safety Rule, and provide you with ample time to put new practices into effect.
For further information on the Produce Safety Rule or PSA Produce Safety Trainings, please contact Dr. Erin Silva, Assistant Professor, University of Wisconsin Department of Plant Pathology, at [email protected].

From the sand hills of western
Nebraska to the Appalachian
foothills in eastern Ohio,
farmers and ranchers in the North
Central region rise each day to face
challenges, conceptualize ideas that
increase their bottom lines, conserve
the natural resources on their land,
and improve the quality of their lives
and the lives of their community
members.
The Sustainable Agriculture Research
and Education (SARE) program is
a decentralized competitive grants
and education program focusing on
sustainable agriculture innovations,
and run by four regions—North
Central, Northeast, South and West.
Since 1988, North Central Region
SARE (NCR-SARE) has awarded more
than $40 million worth of
competitive grants to farmers and
ranchers, researchers, educators,
public and private institutions,
nonprofit groups, and others
exploring sustainable agriculture
in 12 states. As SARE approaches
30 years of advancing sustainable
agriculture to the whole of
American agriculture, NCR-SARE
has been reflecting on the wide
variety of agricultural enterprises
that have benefited from the
innovative producers, researchers,
and educators who look to
SARE for grants and educational
resources—operations large and
small, rural and urban, crop and
livestock, conventional and organic,
and everything in between.
Across the Midwest, savvy producers
have demonstrated that products that
are different in appearance, season, or
origin can command a higher price
than their traditional counterparts.
Since 1988, NCR-SARE has supported
research and development in fruits
and vegetables and the lucrative
markets they can offer. From heirloom
tomato growers and researchers who
have used SARE grants to advance
season extending production methods
BY MARIE FLANAGAN, NCR-SARE COMMUNICATIONS SPECIALIST
NCR-SARE:Advancing Sustainable Innovations in Agriculture for 30 Years
and variety trials, to a growing elderberry industry that
is becoming a model for how farmers and Extension can
partner to build specialty crop markets from the ground
up, SARE supports efforts that improve small farm
profitability and keep more consumer food dollars within
local economies.
NCR-SARE values projects that conserve natural
resources while bolstering agricultural profitability and
productivity. Some of the first grants NCR-SARE awarded
in 1988 went to cover crop research. Since SARE and the
Conservation Technology Information Center (CTIC)
began their annual cover crop survey in 2012, there
has been a steady increase in cover crop acreage among
participants. In this year’s survey, farmers said they
committed an average of 400 acres each to cover crops in
2016, up from 217 acres per farm in 2012. While a large
majority of the farmers who took the survey—80%, or
1,416 respondents—identified themselves as commodity
producers, the other 20% (354) placed themselves in
the category of horticultural crop or vegetable farmer.
Guided by the insights of farmers across the country in
this survey and the four that preceded it, SARE and CTIC
hope to shed light into the programs and practices that
can aid in the success of users of cover crops and inspire
non-users to adopt the strategy (learn more at http://
www.northcentralsare.org/Educational-Resources/
From-the-Field/2017-Cover-Crop-Survey-Analysis).
We all know pollinators are essential to our environment
and our economy. Seventy percent of the world’s
flowering plants, including more than two-thirds of the
world’s crop species, rely on pollinators to reproduce.
SARE resources such as the Managing Alternative
Pollinators book helps producers learn more about rearing
and management practices for multiple alternative bee
species. And the Manage Insects on Your Farm book
highlights ecological strategies that improve your farm’s
natural defenses and encourage beneficial insects to attack
your worst pests. These two books are an example of the
myriad of the books, bulletins, videos, curricula, fact
sheets available through SARE’s Learning Center. It is
a treasure trove of sustainable agriculture information.
Access it online at http://www.sare.org/Learning-Center
Looking forward, SARE is preparing for an important
national sustainable agriculture event, the Our Farms,
Our Future Conference, hosted by SARE and National
Center for Appropriate Technology (NCAT/ATTRA) on
April 3-5, 2018 in St. Louis, Missouri. This national event
will bring together our diverse agricultural community:
farmers and ranchers, agricultural professionals,
agribusiness stakeholders, students, researchers, scientists,
agency representatives, and nonprofit leaders. Visit us
online to learn more about the conference: http://www.
sare.org/Events/Our-Farms-Our-Future-Conference
The NCR-SARE Farmers Forum is an event that
gives NCR-SARE grant recipients the chance to share
information about sustainable agriculture practices
with a regional audience. The talks focus on research,
demonstration, and education projects that promote
sustainable farming and ranching. The projects emphasize
the three pillars of sustainable agriculture: environmental
stewardship, profitability, and social responsibility.

Some of you may be
wondering if the federal
rule to protect your
farm workers from pesticide
exposure is still in effect, or if it
was delayed.
The simplest, but still
confusing answer is, “Yes it is
and yes it was.” And we can
also tell you that, if you already
have a worker protection
program, keep doing what
you’re doing. The Worker Protection
Standard is not going away.
Some background, if you’re not
familiar with the story: The Worker
Protection Standard, or WPS, was
developed by the Environmental
Protection Agency to protect
agricultural workers and pesticide
handlers from pesticide exposure
on farms, forests, greenhouses
and nurseries. In January, a
major revision to the federal rule
took effect. The American Farm
Bureau Federation and the
National Association of State
Departments of Agriculture,
or NASDA, had asked EPA to
postpone the rule revisions,
but EPA denied their requests.
In February, NASDA again
petitioned EPA to postpone
the revisions. This time EPA
agreed and said that the federal
agency would “extend the
implementation of all worker
protection provisions.”
This means there will be changes to
WPS, but we don’t yet know what
those changes will be, nor do we
know when those changes will take
place. Even though EPA agreed with
BY JANE LARSON, WORKER PROTECTION SPECIALISTWISCONSIN DEPARTMENT OF AGRICULTURE, TRADE AND CONSUMER PROTECTION
8 | A Wisconsin Perspective
What’s Going On with Worker Protection?
2017 Volume 9 Issue 3 | 9
the petition, the agency
must go through a
formal process of
posting information
in the Federal Register.
It’s likely that EPA will
take public comments.
This could be a lengthy
process, lasting a few
months or longer. It’s
unknown if the entire
revised rule will be
suspended, or just some
portions. It’s safe to say
that worker protection
is not going away; it’s a question of
which version of the rule to follow.
When we have more information,
we will notify you through various
commodity groups and the
agricultural media.
So what is a Wisconsin grower to do?
Keep in mind that the revised rule that
took effect in January is still in place.
Our 14 environmental enforcement
staff are visiting agricultural
establishments in Wisconsin, including
orchards, vineyards and other fruit
and vegetable growing operations, to
share information on the revised rule
and to do inspections.
Our department has taken a
“compliance assistance” approach
to the new portions of WPS. This
means that growers have time
to learn the new requirements
and incorporate them into their
operations without penalty. This
includes requirements such as:
• Providing safety data sheets for
all applied pesticides
• Putting a system in place to
capture pesticide application
information for at least two
years
• Medical evaluations, annual fit
testing and training for pesticide
applicators and
handlers when the
product label requires
the use of a respirator
• No pesticide applicators
or handlers under age
18 (family members are
exempt)
Other requirements have
always been part of the
rule, such as providing
decontamination supplies,
training workers and
handlers in pesticide
safety and warning workers about
pesticide applications. We will
continue to enforce those provisions.
Again, if you have an existing worker
protection program, just keep doing
what you’re doing. If you aren’t
sure what is required, contact Jane
Larson, DATCP worker protection
program specialist, (608) 224-4545,
[email protected]. You
can also find information online
at datcp.wi.gov. Search for “worker
protection”. You can find resources
such as the new WPS How to Comply
manual and a self-review checklist at
pesticideresources.org.
Sour rot of grapes is a late season
scourge that can quickly convert
a beautiful crop of wine grapes
into a smelly, rotting heap of mush
crawling with fruit flies and yellow
jackets. Sour rot turns berries of white
varieties tan (Figure 1), while berries
of red varieties turn pink or brick red.
Berries become soft and watery, and
in late stages of decay, emit a vinegary
(acetic acid) odor, referred to by
winemakers as volatile acidity. Sour rot
decay typically occurs in the absence
of visible mold, but common fungal
pathogens such as Botrytis, the cause
of bunch rot, or the fungus Aspergillus
can colonize clusters that have sour rot
(Figure 2). Sour rot can be severe one
year and absent the next, as it is highly
dependent on rain and warm weather
as harvest approaches. As with
most fruit and cluster rot diseases,
varieties with tight clusters are more
susceptible to sour rot than varieties
with loose clusters.
What causes sour rot?
A complex of common yeasts and
bacteria act together in causing
soft rot. Yeasts convert sugar in
berries to ethanol, and then species
of Acetobacter and Gluconobacter
bacteria convert the ethanol to
acetic acid (vinegar). Fruit flies, both
the “regular” fruit fly (Drosophila
melangaster) and spotted wing
Drosophila (Drosophila suzukii), are
attracted to rotting berries (Figure
3), and research by Megan Hall and
Wayne Wilcox of Cornell University
suggests that fruit flies may actually
be a source of acetic acid producing
bacteria, harboring them in their guts.
Other studies show that sour rot is
triggered by fruit fly oviposition. In any
case, yeasts and bacteria infect berries
through wounds, and the disease often
takes hold after berry skin is breached
by birds, hail, grape berry moth, wasps,
or berry cracking that happens when
fruit take up excessive water after a
heavy rain.
How does sour rot develop?Research in Ontario by Wendy
McFadden-Smith shows that berries
become susceptible to infection after
they reach about 15oBrix; minor
infection occurs at 13oBrix and no
infection at 10 oBrix. For a few reasons,
rain is needed to get sour rot started:
BY PATRICIA MCMANUS, VILAS DISTINGUISHED ACHIEVEMENT AND SORENSON PROFESSOR AND CHAIRDEPARTMENT OF PLANT PATHOLOGY, UNIVERSITY OF WISCONSIN-MADISON
of GrapesSour Rot
10 | A Wisconsin Perspective
it can cause rapid berry swelling and cracking; it provides
moisture that promotes growth of yeasts and bacteria; and
it washes yeasts and bacteria into cracks and other open
wounds on berries. After infection, sour rot develops quickly
at temperatures of 68 to 77 oF, more slowly at 59 to 67oF, and
not much at all when temperatures are less than about 59 oF.
In Wisconsin, any or all of these conditions can prevail in the
weeks leading up to grape harvest.
How can sour rot be managed? There is no “silver bullet” recommendation for controlling sour
rot. With multiple microbes and fruit flies implicated in causing
sour rot, disease management requires integration of multiple
tactics.
• Manage the canopy so that the microclimate is less
favorable for growth of the sour rot yeasts and bacteria.
Shoot thinning, leaf pulling, and hedging will improve
air circulation and reduce the time that leaves and berries
remain wet from dew or rain, thereby making conditions
less favorable for sour rot, Botrytis bunch rot, and
Phomopsis berry rot.
• Prevent injury to berries, especially after berries reach
15oBrix. Deploy bird netting and spray for grape berry moth
if this pest is present.
• Control fruit flies. Research by Wilcox and colleagues in
New York showed that using insecticides to control fruit
flies reduced sour rot severity significantly. The best results
were achieved by spraying after berries reached 15oBrix but
before sour rot symptoms appeared. It’s less clear if spraying
insecticide after symptoms develop would be effective.
Consult a current pest management bulletin available
through University of Wisconsin-Extension or other states’
extension services for details on products, rates, and pre-
harvest intervals.
• Kill bacteria and yeasts with Oxidate or similar hydrogen
peroxide-based disinfectants labeled for use on grapes.
There is little research to substantiate this recommendation,
but Wilcox has demonstrated that weekly applications
of disinfectants, including Oxidate, reduce sour rot
severity if sprays are started after berries reach 15oBrix
but before symptoms appear, and if used in conjunction
with an insecticide to control fruit flies. Note that “used
in conjunction with” does not mean tank-mixed; as a
strong oxidizing agent, Oxidate is incompatible with many
pesticides. Therefore, if both an insecticide and Oxidate are
used, separate the sprays by a few days. 2017 Volume 9 Issue 3 | 11

Aphids represent a summer-long pest in apple production. Although they are most
damaging to young trees, when populations get out of hand they can reduce the vigor and could cause a loss of yield even on more established trees. There are five species of aphid that are most often seen on apples in Wisconsin, which will be discussed below. These insects as well as many others have been the subject of articles published in the Wisconsin Fruit News, which can be found on the Wisconsin Fruit website at this address: https://fruit.wisc.edu/.
The Rosy Apple Aphid, Dysaphis plantaginea, is one of the more potentially problematic aphid species found in Wisconsin apple production. Nymphs (1/10 – 3/4 inch long, pale yellow or pink to rosy brown or purple) hatch between silver tip and ?-inch green. They feed on sap inside newly emerging leaves and flower buds. The winged or wingless adults are 3 mm long and purple-pink. They live in colonies on terminal growth, and are
most prevalent from tight cluster to pre-pink, when they feed on both leaves and developing flower buds. Damage symptoms can include leaf curling, misshapen fruit, and sooty fungus growth where honeydew dropped onto leaves and fruit. Each female produces up to 185 young. The 2nd, 3rd and 4th generations on apple produce some winged offspring which fly to plantain, dock, or other weeds for the summer. By fall, winged females and males fly back to apple, mate, and lay eggs on the bark of the tree, where they overwinter to hatch again in the spring.
Monitor for rosy apple aphids by looking for curled leaves, then looking on the underside of the leaves for the pinkish-red aphids. If there is on average more than one tightly curled leaf-cluster per tree, spraying is recommended. See the table below for information on what

12 | A Wisconsin Perspective
Curled leaves are characteristic of aphid damage. Ants or ladybeetles are also often seen on aphid leaf curls.
Rosy apple aphids on the underside of a leaf.
insecticides can be used to control rosy apple aphids. At lower densities, there are several cultural control methods that can help prevent rosy apple aphid outbreaks. Some cultivars are more susceptible to aphid damage, such as Cortland, Ida Red, Golden Delicious, Rose, York, and Stayman, so an orchard with high aphid pressure may consider staying away from these cultivars. You can also decrease aphid pressure by removing alternate host plant species, such as plantain and dock, and by keeping trees pruned to allow airflow. Rosy apple aphid can be controlled pretty well by natural enemies such as larval lady beetles, lacewings, syrphid flies, and Braconid wasps. These can be nurtured in your orchard by planting flowering areas to provide nectar as a food source for the adults of these predators, and by avoiding pyrethroid sprays.
Wooly Apple Aphids, Eriosoma lanigerum, become increasingly prevalent as the season goes along, and feed on leaf axils and terminal shoots. The nymphs and adults (1/20 – 1/16 inch long) are reddish-brown, but often covered with a downy protective waxy secretion, resembling “wool”. The adults can be winged or non-winged, and have shortened antennae. Throughout the summer they feed on apple roots, bark, leaves and occasionally fruit, causing nodules and cankers to form on roots and woody parts of the tree. They overwinter as eggs on elm tree bark or nymphs on apple roots.
You can monitor for adults throughout the summer, paying extra attention to pruning scars, crevices where branches or twigs form, or other areas of potential damage. There is no known treatment threshold for this pest, as damage to the top of the tree most likely also indicates cankers being formed on the roots. However, there
are some cultural control strategies to minimize the likelihood of wooly apple aphid populations taking hold in your orchard. Because many overwinter on elm trees, it may help to remove nearby elms from your orchard. Additionally, there are resistant cultivars (such as Northern Spy) and rootstocks (such as Malling series 106 and 111) that will not be damaged by wooly apple aphid. Similarly to the rosy apple aphid, natural enemies may be able to do a good job of controlling this pest if populations are encouraged by providing nectar resources and minimizing the use of broad-spectrum insecticide applications.
A table comparing how to identify, monitor, and control rosy apple and wooly apple aphids is provided on the next page.
The other species of aphid you may see in apple orchards this summer are unlikely to cause significant damage to the trees. The Green Apple Aphid, Aphis pomi, and the Spirea Apple Aphid, Aphis spiraecola, are indistinguishable from each other in the field. While rosy apple aphids are a pink-red color, these other species are yellowish-green. All three species feed on the underside of leaves, and cause leaf curling similarly to the rosy apple aphid. To scout for green and Spirea apple aphids, randomly select 10 shoots (not watersprouts) on each of five trees per block to examine
for curled leaves (check to see if leaf curling is caused by these or rosy apple aphid, as the economic threshold for rosy apple aphid is much lower). If, on average, more than four leaves per shoot have aphids, a chemical spray may be warranted.
Another apple aphid, the Apple Grain Aphid, Rhopalosiphum fitchii, appears earlier in the spring than our other aphids, but rarely causes economically significant damage in Wisconsin orchards. Apple grain aphids can be distinguished from other species because their antennae are much shorter than their body-length, and they have a dark stripe running down their back.
For all species of aphids, there are a number of predators and parasitoids present in Wisconsin orchards, which are able to do a pretty good job of keeping aphid populations under check. However, some broad-spectrum insecticides, in particular pyrethroids, have been shown to reduce populations of these natural enemies, and so may cause an upsurge in aphid numbers. It is recommended to avoid or reduce the number of broad-spectrum insecticide applications for this reason. If an insecticide spray is required for aphid control, you can refer to the current Midwest Fruit Pest Management Guide for recommendations.

Meet Yi WangYi WangAssistant Professor & Extension Potato and Vegetable Production Specialist, UW-Madison, Department of Horticulture
Cell Phone: 608-335-0933
Email: [email protected]
I am originally from China, but I lived in Madison for 7.5 years before moving to the west, so Madison is like my second hometown. Glad to be back, Badgers! I got my Ph.D. in Potato Physiology from UW-Madison Horticulture, and did two years of postdoc with previous vegetable production specialist AJ Bussan before joining University of Idaho as an assistant professor in potato physiology. As I am starting my new potato and vegetable sustainable production extension program, I am open to conversations with our growers and industry to learn more. Please feel free to email, call, text or schedule in-person visits with me so I can travel to your farm and have my feet on the ground. My program will focus on improving the water use and nitrogen use sustainability of vegetable cropping systems.
2017 Volume 9 Issue 3 | 15
What is your educational/professional background? I grew up in Zhengzhou, China and earned my B.S. degree in biological science from China’s Nanjing Agricultural University. I received my Ph.D. in potato physiology here at UW–Madison and then took a position as an assistant professor at the Kimberly Research and Extension Center at the University of Idaho.
How did you get into your field of research? I love crops, and I love to watch tiny seeds growing into lush, leafy crops. It fills me with energy.
What are the main goals of your current research program? To make recommendations about production management – with a focus on water use and crop fertility – to members of Wisconsin’s potato and vegetable industry to help improve their profitability and sustainability.
What attracted you to UW–Madison? I got my Ph.D. from Madison and stayed here for seven years before taking a job in Idaho, so coming back to Madison is like coming home.
What was your first visit to campus like? I was very impressed with the lakes and the trees on campus. Ice cream at Memorial Union was so unforgettable, too.
What is your favorite place on campus? Memorial Union Terrace.
What are you most enjoying so far about working here? There is a fantastic potato science team here at UW–Madison, and I look forward to great collaborations with the team members specializing in different areas.
Do you feel your work relates in any way to the Wisconsin Idea? If so, please describe how. The nature of my job is all about the Wisconsin Idea. As an extension specialist in potato and vegetable sustainable production, I am working closely with members of the Wisconsin potato and vegetable industry on a daily basis. I learn about their needs by reaching out to them, conduct science-based applied research to address those needs, and then disseminate the research results back to them. I plan to have research plots on commercial farms in the future to directly demonstrate my research to the growers. I enjoy having a great working relationship with them.
What’s something interesting about your area of expertise you can share that will make us sound smarter at parties? Potato is rich in vitamin C, a powerful antioxidant that can help the human body form and maintain bones, blood vessels and skin. A 5-ounce potato will supply nearly 50% of an average adult’s daily requirement for vitamin C.
Hobbies/other interests: Travelling, playing accordion, piano and keyboard.

disease of tomatoes and potatoes caused by the fungal-like oomycete pathogen, Phytophthora infestans. This pathogen is referred to as a ‘water mold’ since it thrives under wet conditions. Symptoms of tomato or potato late blight include leaf lesions beginning as pale green or olive green areas that quickly enlarge to become brown-black, water-soaked, and oily in appearance (Figure 1). Lesions on leaves can also produce pathogen sporulation which
looks like white-gray fuzzy growth (Figure 1, 2). Stems can also exhibit dark brown to black lesions with sporulation. Fruit symptoms begin small, but quickly develop into golden to chocolate brown firm lesions or spots that can appear sunken with distinct rings within them (Figure 2); the pathogen can also sporulate on tomato fruit giving the appearance of white, fuzzy growth. The time from first infection to lesion development and sporulation can be as fast as 7 days, depending upon the weather. In WI, as in several other U.S. regions, late blight
has been identified on tomatoes and potatoes in each of the last 8 years. On July 26, 2017, we confirmed late blight on tomato in Waukesha County, WI. Since that time, 12 more WI counties have had confirmed late blight on tomatoes and/or potatoes including Pierce, Dane, Portage, Waushara, Jefferson, Iowa, Kenosha, St. Croix, Polk, Crawford, Clark, and Columbia (in order of confirmation date). It is important to protect susceptible crops with fungicides in both conventional and organic production systems.

Management: The clonal lineages, or strains, of Phytophthora infestans from field infections from Wisconsin that have been tested, to date, are US-23 and US-8. Most of the late blight detected in WI last year, as well as in the rest of the U.S. has been type US-23 which is known to be aggressive on potato and tomato, and is of the mating type A1. In our research, we have demonstrated that the US-23 type will infect tomato, potato, hairy nightshade, black nightshade, and petunia; select cultivars of eggplant, pepper, and tomatillo did not become infected. US-23 produces roughly twice as many spores per lesion as other late blight genotypes and has great potential to rapidly reproduce and spread. US-8 was detected during epidemics of Wisconsin in the late 1990’s, then again in 2013, 2014, and currently in 2017. US-8 is of the mating type A2 (and can mate with US-23) and is resistant to the phenylamide conventional fungicide group. Because Pierce, St. Croix, and Jefferson Counties
have had confirmed reports of both US-8 and US-23 clonal lineages this season, it is very important that late blight is well managed at season’s end and through the winter months to limit viability of the pathogen and risk of mating and forming soil persistent spores.
Some tomato cultivars have resistance to late blight and are listed in Table 1. Note cultivars containing both Ph-2 and Ph-3 resistance genes are most resistant (recent release ‘Iron Lady’ is robustly resistant). Several varieties also exhibit some resistance including ‘Pruden’s Purple’ and ‘Matt’s Wild Cherry.’ Potato cultivars with some resistance to late blight include ‘Jacqueline Lee’, ‘Defender’, and ‘Satina.’
Dr. Meg McGrath of Cornell University has an outstanding tomato variety document on late blight resistance that I strongly encourage you to read for further information on varietal performance. Her data is very current
and useful. The link is: http://www.extension.org/pages/72678/late-blight-management-in-tomato-with-resistant-varieties#.VYq8dkYSyqE
The disease forecasting tool (Blitecast) indicates risk times for late blight activity and can aid in identifying critical times for preventative fungicide applications. To access Blitecast information for Wisconsin, please go to: http://www.plantpath.wisc.edu/wivegdis/index.htm. Once late blight has moved into a region, it is critical that tomato and potato plants be protected. Fungicides must be present on foliage in order to have a protective, disease-limiting effect. Because new growth is not protected and fungicides can wash off, repeat sprays are necessary. Little disease control can be had when fungicide applications are made only after disease onset. A 2007 study compared copper and non-copper containing organic-approved fungicides (such as Sonata, Serenade, and Oxidate)
18 | A Wisconsin Perspective
for late blight control on potato. Results from replicated trials showed that the best organic-approved fungicide for potato late blight control was copper (Dorn, et al. 2007. Control of late blight in organic potato production: evaluation of copper-free preparations under field, growth chamber, and laboratory conditions. Eur. Journal of Plant Pathology 119:217-240). Copper containing fungicides have provided some of the best preventative control against late blight in multiple U.S. trials in recent years as well. Table 2, below, lists some of the certified organic copper formulations (please check up on the allowability of specific formulations if you are certified organic).
In the past few years, we’ve been investigating efficacy of non-copper organic fungicides and have demonstrated good control of tomato late blight with EF-400 under laboratory conditions. Dr. William
Kirk of Michigan State University has conducted field trials with EF-400 plus ExCit (now BacStop) on potatoes and corroborated our laboratory efficacy results. Good field control of potato late blight was demonstrated with weekly applications of EF-400 + ExCit for 8 weeks. Further information on these organic products can be found at: http://anjonag.com/crop-management/ef400-fungicide/
We tested several organic fungicides (and made a few conventional comparisons) (Figure 3 below). Zonix (a rhamnolipid from Jeneil Biosurfactant Company) and EF400 (formerly US Agritech, now Anjon Ag) performed well when applied before inoculation (prior to disease onset). However, recent field tests with Zonix from other states (PA and NC, specifically) have documented poor control of late blight when used in an open field setting with multiple cycles
of the pathogen (typical for ‘real world’ late blight). EF400 has continued to perform well. Fungicides have the best chance of effectively managing disease when applied before disease starts – this is true for all fungicides, conventional and organic. While Oxidate didn’t perform well, keep in mind that it is a contact antisporulant and will kill spores on contact, but will not provide lasting control as a protectant. It has a place to manage spore load, but can’t be relied upon solely to prevent late blight.
Late blight can be managed in an organic system, but control measures need to be proactive and sustained. In the circumstance when late blight gets out of control, early harvest and crop destruct options must be considered to limit development of inoculum that could pose heightened risk for area producers. This is a community disease – management by all growers of susceptible crops is necessary.

Frequently asked questions
Where did this late blight come from? It is uncertain as to where this late blight came from in 2017. We know the late blight pathogen can potentially come from late blight-infected plants (including tubers of potato and fruits
of tomato) that are overwintered in protective structures or in untended compost piles, infected tomato transplants or airborne spores from the region. Seed potatoes can also be a source. At this time, national reports of late blight have come from CT, FL, MA,
ME, MI, MN, NC, ND, NY, ON, PA, VA, WA, WI, and WV. The website: http://www.usablight.org/ indicates location of positive reports of late blight in the U.S. and provides further information on disease characteristics and management.

How do I destroy and/or dispose of my late blight-infected tomato plants?
There are several methods of destroying infected plants depending upon your scale and ability to dispose of plant material in your area landfill: 1) pull up plants by the roots, bag, leave in the sun for a few days for plant and pathogen to die, and put out for trash pickup. This method is OK for a few plants. 2) For many infected plants, plants can be cut at the base and allowed to die in place. Once plants are dead, you can go in and remove stakes, strings, and plastic and dead plant material can be incorporated into the soil. Shallow incorporation of debris is recommended to avoid creating a warm, sheltered environment which would keep the plant tissue and pathogen alive for extended periods of time beneath the soil surface. 3) Plants can be flame-killed with a propane or other torch; and 4) infected plants can be
pulled and placed in a small pile covered over with a dark colored plastic tarp and left in the sun. This will create heat in the pile from the sun beating on the plastic tarp and plants will die within a few days. The winter will provide an excellent freeze kill for exposed infected plants. Do not compost late blight infected plant material, as many piles may have warm centers that can allow plant material and the pathogen to remain viable. The goal is to kill the plants and this will kill the pathogen.
Are tomato fruits from late blight infected tomato plants safe to eat?
Healthy-appearing fruit from late-blight-infected tomato plants are safe for human consumption. If they have been infected, but aren’t yet showing symptoms, they won’t keep in storage. There are some concerns about canning infected fruit because bacteria can enter late-blight infected fruit and impact quality. UW-Extension food science extension specialist, Dr. Barbara Ingham recommends avoiding canning tomatoes that exhibit late blight infection. Further information can be found at: http://fyi.uwex.edu/news/2009/08/26/tomatoes-and-potatoes-infected-with-late-blight-are-they-safe-for-eating-or-preserving/
How fast will late-blight-infected plants die?
This depends upon how many points of infection the plant received, the cultivar (some are more susceptible than others), the history of use of protectant fungicides (such as copper), and on the weather. Hot, dry, sunny weather typically holds back late blight; whereas cool, rainy, overcast weather will cause late blight to progress rapidly killing the plant in 7 to 10 days.
I have tomato or potato late blight in my garden – will I get it next year if I plant tomatoes again?
Most likely the pathogen that we currently have in WI cannot survive outside of living plant tissue. Our strains or ‘types’ of late blight are US-8 and US-23. US-8 is known to be an A2 mating type and US-23 is an A1 mating type. What does this mean? Much like we have male and female ‘mating types’ in our human population, the late blight pathogen requires an A1 and A2 mating type to be present together to form persistent, overwintering, long term spores (oospores). Oospores can persist in soil for many years. Just three counties (Pierce, St. Croix, and Jefferson) have had reports of both mating types, however, we have not detected both types in the same field. Mating is a biological risk, however, we haven’t noted this condition this or past seasons. To reiterate, the late blight pathogen is not likely to overwinter in the soil on its own. It requires living plants or plant parts to remain viable and infective. Therefore, it is critical to kill infected tomato plants and plant parts such as fruit. Potato tubers can also serve as a source of overwintering inoculum and should also be destroyed if found to be infected with the late blight pathogen.
Can late blight be seedborne in tomatoes?
Generally, the late blight pathogen is not considered a seedborne pathogen in tomato.

When taking the family to the apple orchard each fall, there is a list of things you want to accomplish.
Pick a large bag of apples…Check! Eat a caramel apple…Check! Buy a gallon of freshly made apple cider…Check!
October is cider month and apple orchards all over Wisconsin are making cider to utilize their extra apples and to increase their sales. Even smaller orchards can boost their sales by buying pasteurized cider from larger orchards that wholesale it.
Fresh cider is the juice of the apple that includes all the pulp and particles from the pressing process. It differs from apple juice which is filtered and pasteurized to make it shelf-stable. Additionally, cider is a blend of different apple varieties which provides a more complex flavor as opposed to apple juice that is usually from a single variety. Apple cider is believed to have started with the ancient Romans who made a beverage out of crab apples. As you can imagine, fermentation would take place over time to make it ‘hard cider,’ but that’s another discussion.
At the 2017 Wisconsin Fresh Fruit & Vegetable Conference, the Wisconsin Apple Growers Association held their annual Apple Cider Contest. Fifteen entries were submitted in the two categories – Raw/Ultra Violet-treated Cider and Pasteurized Cider. This year’s contest was won by a couple of newcomers.
The unpasteurized cider winner was Mike Graham of Bearfruit Apple Company in Wausau. Mike is a smaller grower with one acre of semi-dwarf trees. He grows his apples for local farmers markets and “I give away a lot
to family and friends,” Mike says. His cider is based on what apples he has available. He presses his cider with a home-built grinder and hand press in 40 gallon batches. His winning cider was 1/3rd Cortland, 1/3rd HoneyGold, and 1/3rd Liberty. He said he would have added some Honeycrisp but he sold out of all those apples. Mike, a retired school teacher, entered for the first time this year and was shocked when he won.
The pasteurized cider winner came from Pieper’s Fruit Farm of Brownsville. John, Bonnie, and daughter, Amberly’s entry is a mix of Honeycrisp, Ida Red, Golden Russet and Dulcet apples. While they have been making cider since they bought the orchard in 1999, they have not been entering the cider contest regularly. Bonnie says they use later varieties to make their cider and use what’s available. John is the cider-maker and tries to use a mix of sweet and tart apples to make his 200 gallon batches. They used to sell wholesale but now all the cider is sold directly from the farm. “People would still come here to buy it anyway,” Bonnie explained.
A trip to the apple orchard just wouldn’t be complete without a gallon or two of fresh cider.

The blueberry maggot fly was first detected in Wisconsin in the summer
of 2016. This direct blueberry pest, which is closely related to the well-known apple maggot, feeds inside blueberry fruit and is damaging to commercial blueberry production in the eastern and southern United States and eastern Canada. In coming years, it is expected to have a significant effect on blueberry production in Wisconsin.
Appearance: The adult blueberry maggot fly looks somewhat like a small housefly with dark bands on its wings, and is very similar in appearance to the closely related apple maggot. Despite being virtually identical in wing-pattern and appearance, apple maggots do not use blueberry as a host, so flies trapped in
blueberry fields are most likely to be the blueberry maggot. The larva, or maggot, is legless and has a single hook-like tooth at the mouth-end.
Host Range: Blueberry is the only commercial crop affected by blueberry maggot. Wild hosts include wild blueberries, lingonberry, dangleberry, deerberry and huckleberries.
Symptoms and Effects: Only a single larva feeds inside each fruit, and as the larva develops the berry will become soft. Damage may go unnoticed until post-harvest, when maggots crawl out of the fruit and become obvious in processed or fresh fruit sales.
Life Cycle: The adult blueberry maggot begins to fly in June or July, and continues through August. After
a pre-oviposition period of at least a week, during which the female feeds and mates, they move into blueberry fields to begin laying eggs. A mated female

will lay a single egg under the skin of the fruit and can lay up to 100 eggs in nearly ripe blueberries during her approximately month-long life span. The blueberry maggot egg hatches within a week. Damage generally first appears in mid-July, and continues until blueberries have been harvested. Each maggot feeds entirely within a single blueberry during its two- to three-week development. After completing development, the larva drops to the ground and overwinters as a pupa in the upper few inches of soil.
A distinctive characteristic of the blueberry maggot is that, although most pupae emerge the following spring, completing one generation per year, some will remain underground for 2 or 3 years. For this reason, spraying to control blueberry maggot one summer will not necessarily eliminate your population for the next season, as there will often still be some pupae in the soil to emerge the following summers.
Scouting Suggestions: Scouting should begin several weeks before blueberries begin to ripen (usually in early June). Commercially available yellow sticky cards, along with a feeding attractant (ammonium acetate or ammonium carbonate), can be placed at a rate of 2 traps per 5 acres. Yellow sticky cards will be most effective if folded in a V-shape with the yellow side facing down. Ideally, these should be checked daily until first detection. The feeding attractant is not specific to blueberry maggot and there may be many other species of fly present on the card. For this reason, it is helpful to bring a hand-lens or magnifying glass when you check traps.
Following first detection, you can also test the fruit directly for infestation rates. To do so, collect approximately
100 berries from throughout your planting, and then spread the berries on a screen above a tray of sand. After four or more hours, you can strain through the sand to find the mature larvae that have dropped down from the berries to pupate. Alternatively, you can break the skin of the berries and mix the berries with a salt-water solution, which causes maggots to float out of the berries.
Control: Some cultural control methods can help prevent blueberry maggot infestations. These include:
• Removing weeds in the blueberry patch, as these can provide habitat for blueberry maggot.
• Removing wild blueberry and huckleberry alternate-host refuges near your plantings.
• Harvesting thoroughly, and solarizing or freezing any damaged or unsalable fruit. Never compost crop waste without first solarizing it, as blueberry maggot pupae can survive in the compost and infest crops in future years.
• Being careful to clean soil away from any equipment or honeybee hives that are moved between blueberry farms, so as not to introduce blueberry maggot pupae in the soil.
Chemical control is recommended if you find on average three or more blueberry maggot flies per trap per week. In general, spraying should begin about a week after the first blueberry maggot flies appear in your traps, and should continue every 7 to 10 days through harvest. Some of the reduced risk chemistries, such as Novaluron, Spinetoram, and Spinosad, are most effective when used as soon as flies
are found in the traps.
Because you will need to spray while berries are ripe, it is especially important to pay attention to the pre-harvest interval when choosing which chemistry to use. Additionally, it may be beneficial to choose an insecticide that also shows efficacy against spotted wing drosophila. Some insecticide classes that are effective against both blueberry pests include spinosyns, carbamates, and organophosphates. As always, it is recommended to rotate IRAC chemical classes to delay insecticide resistance, and to consider the effects on non-target and beneficial insects. Please check the 2017 Midwest Fruit Pest Management Guide for full product recommendations. If you suspect that you have found blueberry maggot in your blueberry plantings, please contact the University of Wisconsin-Madison/Extension Insect Diagnostic Lab at (608) 262-6510, [email protected] or http://labs.russell.wisc.edu/insectlab/contact-us/.

News BriefsFragrant chemical found to control pestsMay help control spotted wing drosophila fly, brown marmorated stink bug
A scent that petunias and snapdragons release to attract pollinators may be an environmentally friendly control for pests like the spotted wing drosophila fly (SWD) and the brown marmorated stink bug.
Agricultural Research Service (ARS) chemist Aijun Zhang discovered the fragrant chemical methyl benzoate, which is also a popular ingredient approved by the U.S. Food and Drug Administration for use in foods, cosmetics and shampoo, can kill these insects and others.
Few choices are available for controlling SWD, which is an invasive species from Asia. It has quickly spread across the United States and can cause significant damage to fruit crops, especially berries.
Zhang, who is with the ARS Invasive Insect Biocontrol and Behavior Laboratoryin Beltsville, Maryland, points out the possibility of a new bio-based pesticide—especially one based on an inexpensive chemical whose residue lasts a relatively short time in the environment—is exciting.
Recently, Zhang was granted a patent for insecticide use of methyl benzoate. ARS is seeking a company to license the technology and bring commercial products to market.
Originally, Zhang was identifying volatile compounds in apple juice that attracted fruit flies. Compounds found in rotting apples and other fruits usually attract flies. He found one compound—No. 19—strongly repelled SWD, and later showed it killed them as well. Compound No. 19 turned out to be methyl benzoate, with its characteristic wintergreen-spicy, floral-fruity aroma.
Methyl benzoate proved to be 5 to 20 times more toxic to eggs of brown marmorated stink bug, diamondback moth and tobacco hornworm than a conventional pyrethroid insecticide, a sulfur and pyrethrin mixture, or some organic products currently on the market.
Next, Zhang will test methyl benzoate’s effectiveness against mosquitoes, fire ants, gypsy moths and stored-product insect pests. All of these insects are developing resistance to standard pesticides.
Zhang is also investigating whether low doses of methyl benzoate could control Varroa mites, the No. 1 problem of managed honey bees today.
You can read more about this research in the June 2017 issue of AgResearch magazine.

News BriefsMidwest Specialty Crop ProducersThe Midwestern Regional Climate Center, the USDA Midwest Climate Hub, and National Drought Mitigation Center (NDMC) are partnering to determine data needs and develop additional tools, educational resources and other information for producers to better adapt to a variable and changing climate. Changing climatic conditions are having a wide ranging impact on agriculture in the Midwest including changes in crop yields, season length, and soil health.
To meet these changes, we will host several workshops with specialty crop producers and extension staff to determine specific data and tool needs as well as climate change education needs this coming winter. To decipher what specialty crop producers are currently using, and to facilitate the adaption and creation of new tools, the following survey has been created to help gather information. From the results of this survey, we will be inviting producers to workshops in December, 2017.

Enhancing PollinatorsThe University of Wisconsin is conducting an assessment to determine practices currently being used in Wisconsin to enhance pollinators. We will use this information to direct further research and outreach efforts. Pollinators are defined as any animal that visits flowering plants and transfers pollen from flower to flower, thus aiding plant reproduction. Wisconsin based pollinators include bees, butterflies, moths, flower flies, beetles, wasps and hummingbirds. In Wisconsin, pollinator-dependent crops account for over $55 million in annual production, but at the same time Wisconsin has been at risk for honey bee colony loss. In April of 2016, Wisconsin produced the Wisconsin Pollinator Protection Plan (https://datcp.wi.gov/Documents/PPPComplete.pdf) which helps guide plans and practices for Wisconsin landscapes. Questions developed for this assessment are based on this Plan.
We are asking you to provide information into this assessment which should take about 20 to 30 minutes. Link to the assessment can be found at: https://uwmadison.co1.qualtrics.com/jfe/form/SV_eUUzWXJkB2MwOIB
