The Nursery Inspection Program works to prevent the spread of plant pests through infested nursery stock. The Agricultural Commissioner’s staff inspects wholesale and production nurseries at least annually, and retail nurseries as needed to assure that injurious pests are controlled or eradicated. Certificates and compliance agreements may be issued to facilitate movement of stock to other states or countries.

Nursery licenses are issued by the California Department of Food and Agriculture with local assistance from the County Agricultural Commissioner. There is also a fee-exempt license available for those selling less than $1000 of nursery stock per year. All sales under the fee-exempt license must be within Mendocino County, and of your own production. Other conditions may apply, please contact our office for more information.

Pesticide Use Enforcement

To file a Pesticide Use complaint, please call our office at (707) 234-6830 and ask to speak to an inspector.

Compliance Assistance

The following information can help you stay in compliance with the multiple regulations around pesticide use. If you feel you need help ensuring compliance, please call our office and schedule a compliance audit. Regulatory actions are not taken based on a compliance audit. The following links and documents provide valuable information for helping you stay in compliance.



Certified Farmer’s Market

A Certified Producer Certificate (CPC) is required for all agricultural products that are to be sold
at the market. CPCs must be filled in completely, including varieties of all commodities. For example, Tomato is a commodity and Sweet 100 is a variety of that commodity. We are no longer able to accept “various” or “unknown” as a variety so please know what you are planting and planning to sell when you supply our office with your information. Look under forms for a sample CPC. These forms are not valid until they are signed and embossed at the Agricultural Commissioners office.

Please note: Due to the time intensive process of creating CPCs, we are unable to process CPCs on a same day basis. Please be prepared to drop off, or send, your information along with a valid phone number so we can call you when the CPC is ready for pick up
