Upcoming regulatory changes on the use of lambda-cyhalothrin products has now reached the political stage.

The Saskatchewan and Alberta governments are urging the Pest Regulatory Management Agency (PMRA) to implement an emergency reinstatement of lambda-cyhalothrin products for 2023 as soon as possible. The PMRA has ruled lambda-cyhalothrin products cannot be used for any crop that may end up as a livestock feed. This restriction has prompted manufacturers, such as Syngenta, to pull their product from Western Canada.

Lambda-cyhalothrin products are registered to control grasshoppers and flea beetles and is found in brand ingredients such as Matador and Silencer. While it is not the only insecticide—it would limit producer control options in what could potentially be a bad year for both insects. Corey Loessin farms in the Radisson area, northwest of Saskatoon.

The second challenge arises with livestock feed. The United States does not have restrictions on lambda products and that opens the door to cross-border trade issues, according to Gord Kubris, the vice-president of trade policy and crop protection at the Canada Grains Council.

The Saskatchewan and Alberta government say an immediate emergency reinstatement of lambda-cyhalothrin products is required for the 2023 growing season. They add this would give the PMRA additional time to make a more informed decision. The Canada Grains Council says the PMRA did not consider some important information when making its decision.
