As background information, electronic copies of the Rodenticide Cluster and Zinc Phosphide REDs and RED fact sheets are available on the internet. This administrative record includes the documents that are physically located in the docket, as well as the documents that are referenced in those documents. Since August 1998 the Agency has collected data and conducted further analysis. Based on all available data, risk mitigation measures to protect birds and non- target mammals could be implemented in the amended RED this fall, if warranted. Except for zinc phosphide, these rodenticides are used primarily for control of Norway rats, roof rats, and house mice in and around buildings, transport vehicles, and in sewers.
Zinc phosphide is used mainly to control field rodents.
Chlorophacinone and diphacinone also have some state special local need registrations for field uses. Anyone interested in these active ingredients is encouraged to attend. An opportunity will be provided at the meeting for interested parties to provide oral or written comments or submit additional information for the Agency to consider.
