Pest Exclusion and Quarantine:
Nursery, Seed, Direct Marketing, and
Import/Export Services

Deputy Agricultural Commissioner Nelson Perez

The Pest Exclusion and Quarantine Program seeks to stop the introduction of harmful pests into Imperial County and California. Pest exclusion is the first line of defense against invasion by exotic pests. Incoming commercial and private shipments of plant material and seed are subject to inspection of compliance with plant import restrictions. Infested or prohibited shipments are subject to regulatory action. Plant quarantines and nursery and seed laws, all protect the industry and environment by excluding plant pests through inspections and certification. Direct Marketing Laws are enforced. Commodities are also inspected and certified prior to shipping to other states and foreign countries.


Production nurseries are inspected to ensure that they meet state nursery cleanliness standards. All plant nurseries need to be licensed with CDFA.

All incoming plant shipments are inspected by Pest Detection and Eradication. Please see this letter for guidance on quarantine restrictions that may affect the disposition of plants entering the county:

Incoming seed shipments are inspected to ensure that the seed meets California seed law and meets quarantine requirements. Seed labelers and facilities are inspected.

Direct Marketing: Certified Producer's Certificates (CPC)

Growers looking to certify their produce for sale at Certified Farmer’s Markets are inspected.

Import and Export Services

Export documents are provided for commodities leaving Imperial County to other states and countries to ensure the commodities meet import requirements. Commodities imported into this county are inspected for quarantine pests.

PQ: Field Inspection Services

This program, also known as the Phytosanitary Field Inspection of Seed program, is performed to certify the mother plants of seed producing fields to allow for export. Not every country requires this inspection and you can contact us if you would like more information on individual country requirements.

This program is to certify ground or container grown plants as free from Ozonium Root Rot (ORR). ORR is a naturally occuring soil bourne fungus that affects over 2,000 plant species. Certification is needed for those wishing to export plants to certain counties or states. Please contact us if you have questions about a particular county's or state's requirements.

Pest Identification Services

The chief purpose of our pest identification service is to provide, at no charge, a means for the agricultural industry and members of the public to have plant pests identified. In addition, it gives our office an opportunity to be on the front lines of early detection of agricultural or landscape pests, as well as providing an opportunity to educate the public on exotic and introduced pests, quarantine restrictions, and safe and appropriate pest control options. Our expertise and resources limits our ability to identify pests of a non-agricultural nature, which may exclude pests that have human health effects. If a pest problem is presented that is one that is best confirmed by a medical laboratory and treated by a doctor, such as human parasites, we will refer these calls to public health or advise the caller to consult a doctor.

Additionally, for the safety of our staff, if a pest is found in the home, we would ask that the resident collect the pest and provide it to staff. Pests may be submitted via mail, drop off at our office, or we may send someone to pick up the sample at our earliest convenience.

We would encourage anyone interested in these services, to contact us. Emailed photographs of pests are encouraged, but a physical sample may be required for accurate determination.
