Farmers Needed for Second Year of Soil Pest Research in Corn and Soybean in Southern Minnesota

Drs. Fei Yang, Extension corn entomologist, and Bob Koch, Extension soybean entomologist, are continuing a project to evaluate pests that feed on seeds and seedlings in corn and soybean fields in southern Minnesota. In areas with severe infestations, these pests can cause significant stand losses or even require replanting of fields. Despite these potential impacts, much remains unknown about these pests in Minnesota corn and soybean. This article serves as a request for additional cooperating farmers for 2025, and an update on results from 2024.

Request for cooperating farmers for 2025

They are seeking cooperating farmers in southern Minnesota to allow their research team to sample corn and soybean fields from April to June 2025.


They are especially interested in sampling corn and soybean fields with the following characteristics:

  • have recently come out of pasture, CRP, etc.,
  • are no-till,
  • are following cover crops,
  • have high organic matter, and/or
  • have not had insecticide seed treatments used in recent years.

However, the sampling will not be limited to fields with those characteristics.

Farmers with fields selected for sampling will receive a free report on the pests encountered in their fields.

Please fill out this short form by March 31, 2025 if you are interested in allowing their research team to sample your field.

If you have questions, contact:
Hunter Ness (graduate student in Entomology), nessx205@umn.edu or 612-289-3475.

Update on 2024 results

We conducted soil insect surveys in 24 corn and soybean fields across southern Minnesota. These surveys consisted of two parts:

  • Dig out 1 cubic foot of soil from 5 or 7 locations in each field, and sift through for wireworms and white grubs.
  • Deploy 10 “baits” per field. Baits consisted of a ball of germinating corn and wheat buried 6 inches below ground. Baits were collected 2 weeks later and brought back to the laboratory to detect any wireworms or white grubs.

Overall results

Soil pest pressure was low in all of the fields we surveyed. White grubs were found in 7 fields and wireworms were found in 6 fields. All fields sampled showed pest pressure below the economic thresholds of 2 white grubs or 1 wireworm per soil sample or per trap.

The 15-Year Bet Behind Every New Variety

Video: The 15-Year Bet Behind Every New Variety!



Canada is trying to decide how much agricultural research capacity it can afford to lose. Brian Rossnagel believes the better question is whether the country can afford to rebuild it.

The longtime barley and oat breeder makes the case with a simple fact about his profession: the consequences of today’s decisions may not become visible for 10 or 15 years.

“Pick the right parents. That’s the biggest thing,” Rossnagel says. “If you pick the wrong parents, you’re not going to get anywhere—and you don’t know that until 10 years, 15 years later.”

That warning carries particular weight as Agriculture and Agri-Food Canada moves to reduce spending and streamline parts of its science operations. The department’s 2026–27 plan anticipates the loss of approximately 665 positions by 2028–29 and says some research will be reduced where capacity exists in academia or industry. AAFC says the changes will make its science operations more cost-effective over the long term.

For Canada’s seed industry, Rossnagel’s career illustrates what is at stake.

This fall, the retired University of Saskatchewan breeder will be inducted into the Canadian Agricultural Hall of Fame. During his 35-year career at the Crop Development Centre, he helped develop more than 100 barley and oat varieties, including CDC Austenson—one of Western Canada’s most widely grown feed barleys. His induction recognizes not only those varieties, but the collaboration and research system that made them possible.

Rossnagel is quick to emphasize that none of it was the work of one person.

“The first thing I thought about was all the other people who contributed to whatever success I and my program had over the years,” he says. “We know that it’s not an individual who does this. It’s a group—a team.”

That team extends well beyond the breeder whose name appears beside a variety. It includes technicians, pathologists, quality specialists, statisticians, regional testing sites, seed growers and industry partners. It also includes the breeders who came before and those who will carry the germplasm forward.

CDC Fraser barley, for example, moved through three breeding careers. Its parents came from Brian Harvey’s program. Rossnagel advanced the material after Harvey retired, and Aaron Beattie later guided it through registration and release.

That kind of handoff is normal in plant breeding. The person who makes the original cross may never see the resulting variety reach farmers.

It also explains why lost research capacity cannot simply be switched back on when budgets improve.

“If you shut it off, it’s very, very difficult—and particularly costly—to start it up again,” Rossnagel says. “If you have to start from scratch, it’s going to be at least 10 years before anybody notices whether you’re getting anything done or not.”

The concern is not simply how many experimental lines Canada can process. Modern equipment, statistical tools and genetic technologies allow today’s breeding programs to evaluate tens of thousands of lines—far more than Rossnagel could handle when he entered the field in the early 1970s.

But efficiency and automation do not generate every idea.

“If you pare back down, and instead of having six or seven individual scientists concentrating on wheat breeding, you go down and say three people could handle all this, well, that’s half the ideas gone,” he says. “Particularly if you happen to lose the three people who had the really neat and innovative ideas, boy, that’s a problem.”

It is a timely distinction for Canadian agriculture. Consolidating programs may preserve the volume of material moving through a system, at least initially. It may not preserve the diversity of thinking, regional knowledge or willingness to pursue unconventional crosses.

That regional knowledge matters because Canadian agriculture is not one uniform production environment. A variety suited to southern Alberta may face different disease, moisture and maturity pressures than one grown in Manitoba, Ontario or Atlantic Canada.

“Agriculture is applied biology,” Rossnagel says. “Biology, all around the Earth, moves from the poles to the equator. It does not move from Newfoundland to B.C. like politics do.”
