ADAMA Canada recalls Silencer, while re-evaluating plan for 2023

The Pest Management Regulatory Agency’s (PMRA) 2021 re-evaluation of the permitted uses of lambda-cyhalothrin, the active ingredient in insecticide products such as Silencer, has at least one company reconsidering offering the affected products for 2023.

ADAMA Canada announced today it will consult with industry before making a final decision on its products with lambda-cyhalothrin as an active ingredient — Silencer and Zivata.

Syngenta also offers Matador, which contains lambda-cyhalothrin.

The PMRA decision on the active ingredient published in April 2021 requires that products containing lambda-cyhalothrin be labeled with new usage guidelines, including restrictions on using sprayed crops for feed use. Companies were given 24 months to implement the changes.

ADAMA Canada says that in recent days, some ag industry participants have questioned whether it is feasible to use the product at all considering how difficult it is to trace where crops will be used after they leave the farm.

“We want to understand what the practical implications are behind the re-evaluation decision,” says Cornie Thiessen, general manager of ADAMA Canada. “We will be pausing our plans on products featuring lambda-cyhalothrin until we understand the downstream implications of this for grain handlers and growers.”

“The product has been recalled for the purpose of relabeling in preparation for the April 2023 rule change,” says Thiessen, in a statement shared with RealAgriculture. “ADAMA Canada is consulting with the industry to see if it’s still worth selling the product with the new label. At this point, we aren’t sure whether this product will be available to farmers next year.”
