Program Information The California Department of Food and Agriculture (CDFA) Pest Detection/Emergency Projects Branch (PDEP) is responsible for the early detection and prompt eradication of serious exotic agricultural pests. The Branch accomplishes its mission by conducting a statewide trapping program, staffed by county and state inspectors, for exotic insect pests; by implementing special surveys for significant agricultural pests and plant diseases for which traps are not available; and by providing emergency eradication services using the best available technology. The primary objective of the emergency project component is to quickly and efficiently eradicate incipient infestations of serious agricultural pests, thereby preventing permanent establishment and subsequent spread in California.
