Critical Uses of Chlorpyrifos

Back to Pest Management Projects

Identifying and Managing Critical Uses of Chlorpyrifos in Alfalfa, Almonds, Citrus and Cotton: DPR contracted with the University of California Statewide Integrated Pest Management Program (UC IPM) to convene industry leaders to work together to create commodity-specific guidelines regarding chlorpyrifos use in four important California crops. Participants included industry representatives, UC Cooperative Extension specialists, pest control advisers, growers, and project staff from DPR and UC IPM. Data and other information were gathered on chlorpyrifos's role in pest management systems in alfalfa, almond, citrus, and cotton, and critical uses were identified. A report presents the findings of crop-specific teams and includes pest profiles of important arthropod pests, management options for each pest, the criticality of chlorpyrifos in each crop's IPM system, and recommendations for research, education, and extension.
