Reducing VOC Emissions from Field Fumigants
Subscribe to receive periodic e-mail updates on activities of DPR’s VOC Program.
Regulations to reduce emissions of volatile organic compounds (VOCs) from fumigant pesticides apply to applications of methyl bromide, 1-3 dichloropropene, chloropicrin, metam sodium, potassium N-methyldithiocarbamate (also called metam-potassium), dazomet, and sodium tetrathiocarbonate.

Fumigation methods – Field fumigant emissions are reduced in the five geographic areas with specific requirements on how fumigations must be done, prohibitions of some high-emission methods, and limits on other methods.
- Fumigation methods allowed
Emission targets and allowances – DPR sets benchmarks for total pounds of pesticide emissions from May 1 to October 31 in five geographic areas. This can require restricting fumigant emissions by individual growers if emission reduction targets cannot be met by other means.
Reporting of fumigation methods used – DPR tracks VOC emissions by requiring reporting of field fumigant application methods in certain areas.
Licensing – Businesses conducting fumigations must have a supervisor who has a field fumigation license. This is a statewide requirement.
