Dr Eugenia Banks, potato specialist at the Ontario Potato Board, alerted recipients of her email newsletter today that Health Canada recently released its final pollinator re-evaluation decisions for neonicotinoid pesticides.
In a news release, Health Canada says: “After extensive research and review, Health Canada has completed its re-evaluations of the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam in relation to their potential impact on bees and other pollinators, and has released the final decisions for each. The scientific assessments show varying effects on bees and other pollinators from exposure to each of these pesticides.
“To protect bees and other pollinators, Health Canada has announced that it will be cancelling some uses of these pesticides, and changing other conditions of use such as restricting the timing of application. Remaining uses (e.g., treatment on canola seeds and greenhouse vegetables) are not expected to pose unacceptable risks to bees and other pollinators.”
In a news brief published by the Canadian Horticultural Council, it is said that “the PMRA did a thorough science-based risk assessment and accounted for real exposure risks such as plant pollinator attractiveness. For these reasons, most uses on non-attractive crops such as root and tuber vegetables (including potatoes), brassica leafy vegetables, leafy vegetables, and (indoor) greenhouse vegetables remain unchanged. All seed treatments were also approved for continued use.”
