Canada Adopts Restrictions on Certain Neonicotinoid Pesticides
Health Canada has determined to cancel certain uses and adopt restrictions on the timing of the application of the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam after re-evaluations of their potential impact on bees and other pollinators showed that these pesticides may be harmful to these animals. Health Canada notes that remaining uses, such as treatment on canola seeds and greenhouse vegetables, are not expected to pose unacceptable risks to bees and other pollinators. The cancellations and new restrictions will be implemented over a two- to three-year period, in accordance with Health Canada’s Policy on Cancellations and Amendments Following Re-evaluations and Special Review.
Health Canada is continuing to evaluate the potential risks to aquatic insects from the use of neonicotinoids, with a report expected by the end of the year. Current research shows that these pesticides are detected frequently in waterbodies at levels that could be harmful to certain aquatic organisms.
