The PD&E Division provides for the first, second, and third line(s) of defense for Fresno County and California Agriculture against exotic pests. The first line of defense is accomplished through our High Risk and K-9 Inspection Activities. The second line of defense is our Pest Detection Trapping and Special Survey Programs. The third line of defense is through Quarantine Enforcement to prevent pest movement.

Below is a more detailed list of the Programs within this Division. Click any of the links below for additional information.

  • High Risk Inspections are conducted to prevent the introduction of exotic pests through the normal channels of trade. Establishment of exotic pests may adversely effect our natural environment as well as negatively impact our State's economy.
  • Our K-9 Dog Team purpose is to enhance inspection and surveillance activities related to plant products entering the State of California via parcel delivery facilities and airfreight terminals.
  • Our Pest Detection Trapping Program responsibilities are the early detection and prompt eradication of serious agriculturual pests from California. This is accomplished through the operation of a state-wide detection trapping program, and special detection surveys. A second benefit is that negative trapping results assure our trading partners that Fresno County exports are free of exotic pests.
  • Quarantine Enforcement is required when agricultural pests and diseases of concern threaten Fresno County and/or California from within or outside of California borders. Immediate quarantine action may be taken to regulate the production and movement of "host" material from within the boundaries of the infested area, to limit the further spread of the pest.
  • Our Nursery Inspection Program has two missions. The first is to prevent the introduction and spread of agricultural pests through nursery stock and protect agriculture and the consumer against economic losses resulting from the sale of inferior, defective, or pest-infested nursery stock. The second is to provide the agricultural industry with registration and certification services for plant materials.
  • Our Seed Certification Program, along with law enforcement, has a goal of protecting seed consumers, including vegetable and field crop growers, as well as urban landscapers. Samples are drawn for germination and purity testing.
  • Our Phytosanitary Certification and Export Program assists our local shippers by providing documentation for their export commodities stating the commodity is free of specific pests of quarantine concern to the importing country or state. Shipments for export must be certified as meeting the pest exclusion requirements of other countries and states.
  • The Staff Entomologist provides identifications, information, training, and demonstrations on insects and related invertebrates for Department staff and the public.
