Glassy-Winged Sharpshooter Project

Back to Environmental Monitoring Branch
Back to Environmental Monitoring Exotic Pest Projects

Under the guidance of the California Department of Food and Agriculture (CDFA), the County Agriculture Departments use ground applications of carbaryl, imidacloprid, and cyfluthrin to control glassy-winged sharpshooter in several counties. The Environmental Monitoring Branch of the Department of Pesticide Regulation (DPR) monitors selected treatments to provide information on the concentrations of the insecticide in various matrices that may include surface water, irrigation runoff, storm runoff, ground water, soil, air, foliage, fruits and vegetables. Additionally, we may monitor dissipation of the insecticide in foliage, soil and surface water. Toxicity of surface water samples to aquatic organisms may also be determined.

The following are documents and reports on this project:

• Field and Meeting Notes describe sampling site conditions and highlights of public meetings
• Study Protocols Describe monitoring objectives, plans, and methodology
• Reports Provide detailed monitoring and study results
• Presentation and Newsletters Slide presentation of monitoring methodology and results. The newsletters contain layperson summary of monitoring status and results.
• Insecticide References
