Pesticide Use Reporting of Field Fumigant Applications

Back to Regulations to Reduce VOCs by Controlling Field Fumigant Emissions
Back to Pesticide Use Reporting (PUR)

DPR uses pesticide use reports on field fumigant applications to track emissions of volatile organic compounds (VOCs) in five “nonattainment areas” (NAAs, map ) that do not meet air quality standards for pesticide VOCs: San Joaquin Valley NAA, Sacramento Metro NAA, South Coast NAA, Southeast Desert NAA, and Ventura NAA.

As part of their routine pesticide use reporting, applicators must include a four-digit code corresponding to the specific method used in each field fumigation. This reporting requirement is in effect year-round. It is mandatory in all five NAAs, and voluntary in other parts of the state.
