SprayDays California
SprayDays California, launched in March 2025, is a first-of-its-kind statewide system that provides information before California restricted material pesticides are used in production agriculture across the state. The system was developed over four years with extensive public engagement and builds on existing regulatory requirements for pesticide use in California that protect people and the environment.
SprayDays provides information before restricted material pesticides are applied—48 hours in advance for soil fumigants and 24 hours in advance for other restricted material pesticides—viewable on an interactive online map or delivered via optional email and text message notifications.

Background on the Development of SprayDays California
The Department of Pesticide Regulation (DPR) began the development of a statewide system following 2021-2022 State Budget allocations by the California State Legislature to provide the public with access to information prior to intended applications of California restricted material pesticides on farms across the state.
DPR conducted a two-year period of public outreach to inform the development of the statewide information system, including four focus groups and eight public meetings held between 2021-2022, and a series of pilot projects hosted by four counties to test elements of system design in 2022 with an independent evaluation of the pilot project effectiveness conducted by UC Davis Center for Regional Change, and beta testing in 2023 to inform the ongoing development of the technology needed to support the statewide system.
DPR proposed regulations in 2023 to implement the system statewide. The final regulations to support the statewide implementation of SprayDays California were approved in December 2024. The statewide notification regulations became effective February 24, 2025, and DPR began the implementation of the statewide system on March 24, 2025.
