ADAMA Canada to continue selling lambda-cy

The company had said last fall that it would stop selling Silencer in response to a Pest Management Regulatory Agency decision to ban the insecticide on crops intended as livestock feed.

Syngenta had announced at the same time that it would stop selling its pesticide Matador.

ADAMA says the decision to continue selling the insecticide comes after consulting with retailers, farmers and industry organizations on the implications of the PMRA ruling to re-evaluate the permitted uses of the insecticide.

“The bottom line for growers is to read the labeling guidelines carefully. Talk to your full-service input retailer and to your crop buyers so you can make an informed decision about if and when to apply the product,” said Cornie Thiessen, General Manager for ADAMA Canada.

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.
