Chlorpyrifos banned effective 2022

Health Canada’s Pest Management Regulatory Agency is cancelling the registration for chlorpyrifos, a non-systemic organphosphate critical to the control of wireworm and other pests.

 

Re-evaluation of the chemical, the active agent in formulations of Lorsban and other materials, led to the cancellation of label use in food crops.

 

Product labels must be updated by December 10, 2022. 

 

It will, however, be allowed use on canola and garlic crops until Dec. 10, 2024, because there are no alternatives for controlling the pests currently held in check by chlorpyrifos 

 

Remaining acceptable uses include mosquito control, protection of non-residential structures and greenhouse ornamentals, and control of various beetles including Japanese beetle, elm bark beetle and mountain pine beetle.
