Proceedings of the Vertebrate Pest Conference

The role of the California Department of Food and Agriculture (CDFA) is described in regard to its responsibilities in registering vertebrate pesticides and how this relates to Federal (EPA) registration. This includes its role in new product registrations, amended labels, 24(c) Special Local Need registrations, Experimental Use Permits, and Section 18 Emergency Exemptions. California registration requirements for vertebrate pesticides differ from the Environmental Protection Agency requirements in the following areas: Efficacy (performance data evaluation data are required); Biochemical Data (for rodenticides, data is required that describes the metabolic pathway and the mode of action in animal models suitable for extrapolation to human exposure); and Rodenticide Bait Safety (anticoagulant rodenticide baits intended for home use shall contain a dye, and baits containing strychnine shall be dyed with a green color additive).
