Combined, alfalfa, almond, citrus, and cotton represent a value of over $10 billion, and are grown on 2.5 million acres of farmland. Chlorpyrifos is an agricultural insecticide used in these crops as well as other food, fiber, and forage crops in California. Chlorpyrifos is an important tool against invasive pests and endemic pest outbreaks due to its efficacy, value as a resistance management tool, and established international registration status for exporting agricultural commodities. Currently, there are ongoing evaluations at the state and national levels to assess potential human and environmental health risks from chlorpyrifos and to consider what, if any, regulatory actions on chlorpyrifos might provide further safeguards up to and including full cancellation of the registration. The results of the safeguards could change the use of chlorpyrifos, including increased use restrictions and could impact many well-established IPM programs previously developed by UCCE scientists.
