Signal California Pilot Tests Steam as Alternative to Chemical Soil Fumigation Near Schools

Summary

California's Santa Cruz County Agricultural Commissioner launched a $175,000 pilot project on August 6, 2026, funded by the state Department of Pesticide Regulation, to test high-temperature steam as an alternative to pre-plant chemical soil fumigation in berry fields, according to CDPR's announcement. Several berry producers in the Pajaro Valley began testing steam in place of conventional pre-plant soil fumigation starting summer 2026, with research continuing into 2027. Test fields were selected based on proximity to schools and other sensitive community sites to reduce airborne toxic exposure risks. The pilot, led by Agricultural Commissioner David Sanford, arose from conversations with community groups interested in exploring fumigant alternatives near sensitive locations, and will involve collaboration with a University of California researcher, industry partners, berry growers, landowners, and community members, alongside ongoing community outreach meetings.
