Lambda-cyhalothrin label changes now in effect

With seeding operations starting to get underway across the prairies.

Farmers are being reminded that the PMRA label changes for lambda-cyhalothrin came into effect on April 29th.

Canola Council of Canada Agronomy Specialist Ian Epp notes in Canada crops treated with the product can no longer be used as livestock feed:

"In Western Canada, we don't really have a segregated market. There will be some contracts maybe, but food and feed do blend together. In a crop like canola specifically - canola can be simultaneously both food and feed.  If we are crushing the oil maybe the oil is for food, but the meal that is a byproduct of that processing is often used for feed."

Epp says lambda-cyhalothrin is widely used for insect control in a variety of crops, like flea beetles in Canola.

What insect threats are Minnesota corn growers facing, and what research is helping farmers stay ahead of them?

At the 2026 MN Ag Expo, University of Minnesota entomologist Fei Yang shared updates on three Minnesota Corn-supported research projects focused on insect monitoring, seed treatments, and pest resistance.

Current work includes statewide monitoring programs that use pheromone, light, and sticky traps to track key pests such as black cutworm, true armyworm, corn earworm, European corn borer, and corn rootworm. Researchers are also evaluating whether high-rate seed treatments provide effective corn rootworm control and studying the development of resistance in European corn borer populations to Bt corn traits.

These projects help researchers better understand pest pressures across Minnesota and provide farmers with practical information to support informed management decisions.
