The Vegetable Beet: Recent Episodes
Great Lakes Vegetable Producers Network
A live weekly interview and discussion focused on vegetable production challenges and opportunities brought to you by the Great Lakes Vegetable Producers Network. We grow more together. JOIN US LIVE! We will be broadcasting live via Zoom at 12:30 ET/11:30 CT every Wednesday from the first week of March to the first week of September. Login at www.glveg.net/listen.
In this episode, Rue Genger interviews Kevin Anderson and Annelie Livingston-Anderson to learn about the reduced tillage systems they use to produce vegetables and flowers at Good Turn Farm, in Pepin County Wisconsin. Kevin and Annelie share their favorite low-tillage production systems, benefits they’ve seen for soil health, and advice for growers who are getting started with reduced tillage methods. We also hear about the Johnson-Su composting bioreactor that Kevin and Annelie are trialing with the Land Stewardship Project.
In this episode, Rue Genger and Liz Dwyer of Dancing the Land, Clearwater Minnesota, mix philosophy and practicality into their conversation about farming, food, and caring for the land. Liz describes the evolution of the several different reduced tillage systems that she and her partner Curtis use on their land, how their livestock are integrated into annual production systems, and the importance of adaptability and observation in developing systems for your farm.
Deep compost mulch systems are gaining popularity among vegetable growers who want to reduce tillage. In this episode, Rue Genger interviews Jimmy Bauman about the deep compost mulch systems used at Farm Farm in Princeton Minnesota. Jimmy describes the path he and his partner Heather have taken to reduce tillage, build soil organic matter, and refine their deep compost mulch system for vegetable production.

In this episode, Natalie interviewed Meg McGrath, a plant pathologist from Cornell, and Jim Jasinski, IPM coordinator at Ohio State University, about using biofumigation to manage soilborne diseases. We discuss how it works and tips for growers who want to try it on their farms.
In this episode we talk to Anna Testen and Bob Philbrun, from Ohio, about a method for directly competing with and destroying soil diseases by encouraging a special group of microbiology, called anaerobes. Like day shift and a night shift clocking in and out, the anaerobes rule with oxygen is removed from the soil, leaving behind a tilthy planting medium wither fewer plant disease-causing pathogens.
How do we build organic matter on farms without over-fertilizing our soils? And what are realistic goals for increasing organic matter? In this episode, Natalie Hoidal interviews Dr. Nic Jelinski, a soil scientist at the University of Minnesota. They talk about soil formation, how organic matter accumulates in soil, broadening our metrics for soil health, and how different practices like compost additions and cover crops contribute to organic matter in the longer-term.
Across the Great Lakes region, we see vegetable farms with very high levels of soil phosphorus. In this episode, Natalie Hoidal interviews four ecologists who study nutrient leaching in freshwater ecosystems to understand how much it matters for vegetable farms to have high phosphorus levels in their soils, and what we can do about it.
High tunnel crops often look great for the first few years, but as tunnel soils begin to build up salts and alkalinity, we begin to see plant health problems around years 3-5. In this episode, Natalie Hoidal interviews Dr. Elsa Sanchez and Thomas Ford from Penn State about trends they've seen in high tunnel soils, and strategies for dealing with common problems.
In this special mid-winter offering, three university researchers agreed to be interviewed and recorded for this live and in-person show. They were Marty Chilvers, specializing corn and bean diseases; James Dedecker, specializing wildlife management; and Zsofia Szendrei, specializing in insect pests of vegetables. This show is brought to you by Fartless Beans, and Heavy Metal Tube Man.
In this special mid-winter offering, three operations agreed to be interviewed and recorded for this live and in-person show. They were Blake Farms (Armada, MI), specializing in fruits, vegetables, and agritainment; Hoopers Farm Garden (Traverse City, MI), specializing in cut flowers for events; and Will Forage for Food (Grass Lake, MI), specializing in wild food tourism and educational events.
Ben Phillips interviews Lina Rodrigues-Salamanca about how diseases get through the winter. A written synopsis of this content will appear in the January edition of Vegetable Growers News, in a column called Great Lakes Veg Connections.

Natalie Hoidal interviews Dr. Bhabesh Dutta of Georgia, Thomas Bjorkman of Cornell and Susan Scheufele of Massachusetts, a team tackling broccoli production east of the Mississippi. Learn more about their multi-state work on developing varieties and markets and improving pest and disease management.
Caw, Caw, phwump, chk chk boom, arrgghhhh! It doesn't take long in farming to start to sympathize with Elmer Fudd, as it seems mammals are always one wing flap/paw/hoofprint ahead of the limited tools we have. Listen as we chat with James DeDecker about vertebrate pest management (P.S. sounds at the beginning were, in order, bird distress call "squawk box," a propane cannon, a shotgun, and an exasperated grower).
Also check out a library of factsheets, videos and more on vertebrate management available through Michigan State University, plus this article that puts fencing costs in perspective.
This week's show is all about getting set for the 4th growing season; winter! Planting dates are crucial for winter greens to yield during and through the Persephone period when we have fewer than 10 hours of light a day. When to heat? What kinds of insulation options are available? Lewis Jett is here to talk about preparing hoophouses for and tending to winter leafy green vegetables.
Follow up questions can be sent to Lewis at Lewis.Jett@mail.wvu.edu .
With pumpkins starting to color up, do you already have pumpkin spiced lattes on your minds? Next week the Vegetable Beet will be gnawing on the important pumpkin questions. Join Ben Werling of MSU Extension as he talks to the pumpkin duo, Nathan Johanning of University of Illinois Extension and Brad Bergeford of the Ohio State University Extension about how to be the pumpkings and pumpqueens you were meant to be!
Here are some resources that were discussed in this week's episode.

Hold onto your oomycetes, folks! This week Mary Hausbeck joins us from Michigan State University to talk about a group of pathogens called oomycetes, also known as water molds. These include downy mildews on foliage, and the complex of Phytophthora, and Pythium rots on roots and fruits. What makes them different and more challenging than regular ol' fungus and bacteria? With loads of experience and research on these pathogens, Mary will have you saying "ooooo!-mycetes" and "oh!-mycetes" instead of the profanity you might otherwise use.
Keep up with Mary at veggies.msu.edu.
CMV, INSV, TSWV, SqMV, WTF? Viruses are a confounding complex of pathogens of our vegetable crops that can hide in overhead ornamentals in greenhouses and non-crop weeds in fields. How can you prevent them from infecting plants, identify if plants are infected, or manage plants after infection? Brett Arenz, from the University of Minnesota, and Jan Byrne, from Michigan State University, join us to discuss these mysterious plant problems.
Join us this week for the Garlic Guru of Ontario, Travis Cranmer. Garlic is one of those polarizing crops that people love or hate. But, those who like to eat it, tend to really love it. And those who grow it, really love to grow it. Planting in fall, harvested in summer. How strange!? What should you know about seed quality and sourcing, and what do you with the flower scapes of hardneck garlic? Travis will take us from A to Z. No vampires allowed.
There are many things that look like a disease, or insect damage, but they are not! What are they called? These are "abiotic" disorders, and they get their name from being "non-living" causes of plants stress and yield reduction. Cold snaps, heat stress, wind, hail, low spots, and pH and nutrient levels in soil and water are common causes for abiotic disorders, and Becky Sideman is here from the University of New Hampshire Extension to talk out some of the common and tricky ones with us!
Here is Becky's factsheet on Blossom End Rot.
Here is Becky's video about Yellow Shoulders management.
Here are the American Phytopathological Society Compendia that detail disorders in addition to diseases and insects. They are now available for free as pdfs!
Ugh Bugs! Organic cucumber beetle management is an annual ordeal for both conventional and organic growers, but there are more limited options for sprays on organic vine crops. What is it about this bug that makes it so difficult to deal with? What can I do about it with the sprays available, and other tools beyond the boom? Celeste Welty, at The Ohio State University, has pondered and researched these questions in her career as a fruit and vegetable entomologist in the Buckeye State. Join us and learn!
Ope! Starting a farm or transitioning a farm to certified organic is tough! New crops, new pests, new markets, and new paperwork. Jake Overgaard, certification specialist from Midwest Organic Services Association (MOSA), and Vicki Morrone, organic systems academic specialist from MSU, are here to discuss the pitfalls and easily-missed or commonly screwed up things that require extra time to remedy and could have gone smoother for Organic Certification.
You can get more information on organic certification from mosaorganic.org, including a nice set of factsheets to keep your head from spinning.
$temphylium Onion Blight can cost onion growers $ in so many ways. Hear about ways to get a handle on the SOB as Dennis Van Dyk chats with Christy Hoepting about Stemphylium control in onions.
Christy mentions at some point "What the frick is a FRAC?" Here is a quick run down of the products and their FRAC codes from Christy's most recent trial in 2020. "Always be rotating through them and guard the 7's with your life".
Viathon = tebuconazole + potassium phosphite = FRAC 3 + 33
Luna Experience = fluopyram + tebuconazole = FRAC 7 + 3
Luna Tranquility = fluopyram + pyrimethanil = FRAC 7 + 9
Inspire Super = difenoconazole + cyprodinil = FRAC 3 + 9
Quadris Top = difenoconazole + azoxystrobin = FRAC 3 + 11
Merivon = fluxapyroxad + pyraclostrobin = FRAC 7 + 11
Rovral = iprodione = FRAC 2
Scala = pyrimethanil = FRAC 9
Endura = boscalid = FRAC 7
Cabrio = pyraclostrobin = FRAC 11
Quadris = azoxystrobin = FRAC 11

At 35:00, Black Plastic Mulch is a cover of Fake Plastic Trees by Radiohead, with lyrics reworked for the topic of alternative mulches. Lyrics by Ben Werling and Ben Phillips. Performed by Ben Phillips.
A black plastic mulch raised bed
For a fast-growing summer plant
It’s non recyclable
That she brought from a sales man
In a winter of best laid plans
But it left a big mess
Living or dead, we need a mulch
Living or dead, we need...
A novel non-plastic mulch
Or a short-growing legume mulch
That won’t crumble or compete
But I can’t go another day
There’s a price to pay either way
If I just turn my head
Living or dead, we need a mulch
Living or dead, we need a mulch
And if I could yield the same as ever
With mulch that blocks weeds, then leaves forever
By spring time, by spring time
Ben Werling interviewed Cheryl Trueman, who works with Ontario tomato growers at the University of Guelph. Flex your epidemiology muscles-on a non-Covid subject-as we chat about bacterial diseases of tomatoes-how they spread, and what you can do to slow them down. Do tomato plants need to mask up?
Cheryl has an article that summarizes much of what we talked about today. https://onvegetables.com/2019/06/06/managing-bacterial-spot-in-ontario-tomatoes-updated-best-management-practices-for-field-production/
Ben Phillips interviewed Steve Bogash, of Marrone Bio Innovations, and Dan Egel, vegetable pathologist at Purdue.

Our guest is Matt Kleinhenz, from OSU. One of Matt's recent lines of study has been on plant-health enhancing microbial products. There tends to be a lot of confusion in this arena with new terms, claims, and a rapidly evolving industry. So, we have invited Matt to help us get it all straight. You can catch up with Matt's work on his Bugs in a Jug website.
Our guests are Carl Rosen, from the University of Minnesota, and Dan Egel, from Purdue. Carl's research and outreach program is concerned with plant nutrition and nutrient management with particular emphasis on commercial vegetable and fruit crop production. Dan focuses on disease control in vegetable crops. We spoke to them today about what Boron does for plants, and what uses are advisable. Preventing disease? Killing weeds? Ensuring proper nutrition? Foliar or soil-applied?
Meg McGrath, the Mildew Guru from Cornell, spoke with us today to talk all about powdery mildew in vine crops! Meg has spent a career learning how pathogens survive between crops, investigating factors that favor disease development, evaluating fungicides and resistant varieties, developing scouting protocols and action thresholds for timing the initiation of fungicide applications after disease detection.
Here is the main page of resources that Meg has put together on this topic.
https://www.vegetables.cornell.edu/crops/cucurbits/cucurbit-powdery-mildew/
This page includes downloadable lists of varieties that are marketed as having resistance to powdery mildew (and other diseases and disorders), updated conventional fungicide recommendations, and also a comprehensive collection of microbial and oil-based fungicides that are OMRI-listed.
Hindsight is 20/20 when it comes to pest problems when a missed management opportunity passes. What information can help you get ahead of the curve? And what does it all mean? Our guests today are Dan Egel, vegetable pathologist from Purdue, Keith Mason, entomologist and Enviroweather station network manager from Michigan State University, and Cheryl Trueman, vegetable pathologist from the University of Guelph in Ontario. Together we discuss the weather tools available to growers for predicting both insects and diseases in vegetable crops.

Our guests today were Dan Brainard, Professor of Horticulture at MSU, and Stephen Meyers, Weed Scientist at Purdue University. Dan’s recent work focuses on using seedbed prep, mechanical weeders, and cover crops for weed control. Stephen focuses on helping vegetable growers using herbicides safely and effectively, as well as testing new products.
How can growers prepare a seedbed to start off as weed-free as possible?
How does weather affect the activity of pre-emergence herbicides?
Are there any characteristics of herbicides that can be used to predict how their performance and safety will vary in dry vs wet soil conditions?
What tools are most effective for cleaning up small weed escapes in early-sown veggies?
How do pre-emergence herbicides interact with shallow-weeding tools like basket weeders?
In this epidoside we interviewed Anne Verhallen, Soil Management Specialist Horticulture at the Ontario Ministry of Food and Rural Affairs, and Ajay Nair, Professor of Horticulture at Iowa State University about soil dynamics during freeze events, and their potential effects on germinating seed and emerged vegetable plants, assessing freeze damage, and on maintaining transplants when they must be held due to poor planting conditions.
In the first episode, on May 6, we interviewed Amanda Byler, a Family Nurse Practitioner who works with migrant worker communities at Great Lakes Bay Health Centers, and Annalisa Hultberg, University of Minnesota Extension Educator for on-farm food safety, about farm family, farm worker, and customer safety as we enter our production season during a global pandemic.
Some resources that were discussed can be found here.

If you have a vegetable production issue that you would like discussed, simply email it, along with your phone number, to greatlakesvegwg@gmail.com.
The format we’re running with will be a 30 minute interview and discussion with some experts from the region, on topics that seem relevant for the week or month. Then, we’ll open it up for another 15 or 20 minutes for some live audience participation with the hosts and guests of the week.
This coming week, MAY 6: WEATHERING THE COVID-19 CONTENT STORM
We will interview Amanda Byler, a Family Nurse Practitioner who works with migrant worker communities at Great Lakes Bay Health Centers, and Annalisa Hultberg, University of Minnesota Extension Educator for on-farm food safety, about farm family, farm worker, and customer safety as we enter our production season during a global pandemic.
