Lambda-cyhalothrin insecticide cancelled for apples and peaches

The Pest Management Regulatory Agency (PMRA) has updated its guidance on the pyrethroid insecticide, lambda-cyhalothrin. While the agency has reinstated certain feed uses, it has cancelled use on apples and peaches at the request of registrants Syngenta and Sharda-CropChem Limited.  

Here’s a shortened version of the background provided by PMRA. 

Lambda-cyhalothrin is a synthetic pyrethroid insecticide used to control many types of insect pests in various settings. It is used on greenhouse food crops, terrestrial food and feed crops, shelterbelts, turf lawns, livestock, buildings, and ornamental plants. It has been registered for use in Canada since 1996.

On 29 April 2021, Health Canada's Pest Management Regulatory Agency (PMRA) published the Re-evaluation Decision RVD2021-04, Lambda-cyhalothrin and its associated end-use products. As a result of the re-evaluation decision, several uses were cancelled due to human health concerns.
