Abstract

A method is provided for enhancing oxidation of methyl bromide during agricultural fumigations of fields using a fumigant containing methyl bromide. The method comprises adding a methylotrophic bacterium to the soil in an amount effective to provide bacterial oxidation of the methyl bromide. The bacterium preferably comprises a bacterium isolated from agricultural soil, and, in a specific embodiment, comprises a 16S ribosomal RNA gene sequence in the Alpha subgroup of Proteobacteria designated strain IMB-1 (ATCC 202197). The fumigant also includes chloropicrin in an amount reduced to a level which permits said bacterial oxidation but while still enables the chloropicrin to serve as a warning agent for excessive release of methyl bromide from the soil. The soil can be pretreated with methyl iodide. The bacterium is applied to the soil as freeze-dried bacterial cells during the fumigation operation.
