What is the IR-4 Project California?

The IR-4 Project California was established, in part, to manage grant funds provided by the California Department of Food and Agriculture, in support of the National IR-4 Project objectives.  The National IR-4 Project, with funding from the USDA’s National Institute for Food and Agriculture, supports pesticide registrations and non-conventional pest management technologies for specialty crops (food and environmental horticulture) throughout the nation, including California. The funds provided by CDFA are used for additional projects delivering effective pest control tools of particular interest to California specialty crop farmers.
