The Biological Control Program is an integral component of the CDFA Plant Health and Pest Prevention Service's (PHPPS) Pest Prevention Program. The program helps to minimize the economic and environmental impact of noxious weed and insect species through the implementation of biological control programs throughout the state. Implementation requires the rearing of appropriate natural enemies and their release and evaluation in agricultural, natural and urban environments.
The Tehama County Agricultural Commissioner’s office works with CDFA to develop the use of effective biological controls for use on troublesome pests of agriculture, such as the Hairy Weevil for Yellow Star Thistle. If you would like to learn more about this program or others like it, click here.
