title: Degradation of the insecticide fensulfothion by a mixed culture of soil microorganisms.
abstract: Fensulfothion was incubated in nutrient media with a mixed culture of soil microorganisms obtained from sandy loam. The half life of fensulfothion in both inoculated samples and sterile controls was about 16 wk. There was some conversion to fensulfothion sulfone (16% at 6 wk) in inoculated samples, but not in the controls. Traces of fensulfothion sulfide were found in both inoculated samples (less than 3%) and controls (less than 2%). When 1% ethanol was added to the inoculated nutrient mixture the fensulfothion disappeared rapidly (t1/2 congruent to 1 1/2 wk) with 32% conversion at 20 wk to fensulfothion sulfide.
