Re-evaluation of neonicotinoid insecticides : update on pollinator risk assessments.: H113-5/2017-3E-PDF

“The re-evaluations of clothianidin, imidacloprid and thiamethoxam were announced in 2012 (Re-evaluation Note REV2012-02, Re-evaluation of Neonicotinoid Insecticides). These re-evaluations were initiated to assess the potential risk to pollinators in light of international updates to the pollinator risk assessment framework, including information requirements. This Re-evaluation Note provides an update on these re-evaluations. These re-evaluations consider all outdoor and agricultural uses of these neonicotinoid insecticides including soil and foliar applications, seed treatments, and greenhouse and tree injection uses. Both short and long term effects of various exposures are being considered to honey bees and native bees (such as bumblebees). Health Canada's Pest Management Regulatory Agency (PMRA) and the United States Environmental Protection Agency (USEPA) are collaborating on these pollinator assessments, based on the jointly developed harmonized Guidance for Assessing Pesticide Risks to Bees. The Agencies have also been working closely with the California Department of Pesticide Regulation (CDPR)”--Background, p. 1.
