Garlic

 

The Pest Management Regulatory Agency (PMRA) has re-evaluated the use of chlorpyrifos, an organophosphate insecticide, and cancelled its use in fruits, vegetables, cereals, legumes and oilseeds. Food uses will be removed from most labels of chlorpyrifos products by December 10, 2022 with remaining products for food use cancelled by December 2023. Last use dates for garlic and canola have been extended to December 10, 2024.  

 

Currently, there is no alternative control available for darksided and redbacked cutworm in garlic. Interim mitigation measures for garlic include reducing applications to one per season at the lower label rate of 576 g active ingredient/hectare. And buffer zones must be present to protect sensitive aquatic biota. 

 

The PMRA has ruled that the only acceptable uses of chlorpyrifos are for: 

 

-              Outdoor ornamentals for container stock for control of Japanese beetles

-              Mosquito control in standing water

-              Structural use in non-residential areas

-              Tree trunk application for forestry uses
