Pesticide Investigations at WIL

Pesticide Investigations

In 2009, over 156 million pounds of pesticide active ingredients were used in California. While pesticides have contributed to the high quality of life enjoyed in California, their use has not come without cost to the fish and wildlife resources of the State. CDFW formed the Pesticide Investigations Unit in 1964 to address ongoing effects of fish and wildlife from pesticide use. This unit later became part of the Wildlife Investigations Laboratory. WIL continues to protect fish and wildlife from adverse pesticide impacts by investigation of pesticide-related fish and wildlife incidents, involvement in the pesticide registration process, participation in monitoring studies, and education of pesticide users on impacts to fish and wildlife.
