Pest Control Advisers (PCAs) are licensed professional production consultants who serve California agriculture and horticulture producers. PCAs specialize in pest management, but they are also an important resource to producers in a wide range of production concerns related to plant health.

A PCA is licensed by the State of California to engage in the following activities:

• Provide pest management recommendations, which must be in writing.
• Hold self as an authority on any agricultural use.
• Solicit sales of products or services for agricultural use.

PCA specialties are diverse and may help maintain highway vegetation; solve weed congestion in public waterways; assist in pest-free greenhouses, golf courses, turf and landscape; or ensure the growth of healthy, abundant food, fiber and ornamentals from over 9.9 million acres of California farm and public lands.
