California’s pesticide regulatory agency, the DPR, recently recommended adopting a new temporary regulation to restrict the use of chlorpyrifos. Currently, chlorpyrifos is used across more than 800,000 acres in the state on over 60 different crops, including tree nuts, grapes, citrus fruits, vegetables, cotton, and alfalfa. Following the DPR’s designation of chlorpyrifos as a “toxic air contaminant” and its subsequent permanent restriction on its use, this new proposal will introduce additional protective measures to mitigate potential risks associated with pesticide exposure. The agency has advised county agricultural commissioners (CACs) to implement this interim measure starting January 1. “For years, the DPR has worked closely with growers to identify alternatives to chlorpyrifos,”

　California, USA Pesticide The regulatory agency DPR recently recommended enacting a new temporary law to restrict the use of chlorpyrifos.

　　This provisional measure includes:
　　 The aerial application of chlorpyrifos is prohibited.
　　 The use of chlorpyrifos is prohibited on most crops. (For more details, please refer to the DPR website.)
　　Use this Pesticide Areas should be equipped with a 0.25-mile buffer zone and may not be entered until 24 hours after application of the product.
　　The site is located 150 feet from sensitive areas such as buildings and schools.
　　According to the DPR, the use of organophosphates has declined over the past few decades as growers have opted for safer alternatives. Such… Pesticide The usage has declined from 2 million pounds in 2005 to 900,000 pounds in 2016, a reduction of more than 50 percent.
　　In 2015, the DPR designated chlorpyrifos as a restricted substance in California, meaning that only trained professionals holding licenses issued by local agricultural officials are permitted to use it. Pesticide In 2017, chlorpyrifos was added to California’s Proposition 65, which lists chemicals known to cause reproductive harm.
　　In September 2018, following an extensive scientific review and public comment period, the DPR proposed listing chlorpyrifos as a “toxic air contaminant,” which California law defines as an air pollutant capable of causing serious illness or death. The 45-day public comment period concluded on November 9.
　　After classifying chlorpyrifos as a toxic air pollutant, the DPR is required to consult with other agencies—including environmental health risk assessment authorities and the California Air Resources Board—regarding the measures needed to reduce… Pesticide Measures regarding dosage. This procedure may take up to two years to complete.
