Pesticide News Story: EPA Issues Registration Review Final Work Plan for Imidacloprid

For Release: July 13, 2009

EPA has issued a Final Work Plan (FWP) for the registration review of imidacloprid. A neonicotinoid insecticide, imidacloprid is highly toxic to honeybees on an acute exposure basis; however, potential chronic effects on honeybee colonies are uncertain. As part of the registration review process, EPA is requiring field-based data on imidacloprid to better understand its potential impact on pollinators. The Agency also will be working with Federal and State officials, as well as the international community and other stakeholders, to develop data and help us understand the potential impact of the neonicotinoid insecticides on pollinators. For additional information about the Agency's pollinator protections, please visit the Web site. Information about the registration review of imidacloprid is available on the Web site.

Imidacloprid is used on food crops, ornamentals, turf, seed treatments, domestic pets, and structural pests. During the public comment period on the Agency's Imidacloprid Summary Document and Preliminary Work Plan (PWP), issued in December 2008, EPA received over 12,000 comments voicing concern over imidacloprid's potential effects on pollinators. The comments highlighted points to be considered during registration review, but did not change the timeline or data requirements set forth in the PWP. The Agency has addressed the comments in three separate Responses to Comments memos. The PWP, response to comments documents, and FWP can be found in the imidacloprid registration review docket, EPA-HQ-OPP-2008-0844, at www.regulations.gov. Please see:
