Abstract
Fensulfothion (Dasanit®, 0,0-diethyl 0-[p-(methylsulfinyl) phenyl] phosphorothioate) degraded rapidly in a sandy loam soil to a moderately persistent metabolite fensulfothion sulfone (0,0-diethyl 0-[p-(methylsuffonyl) phenyl] phosphorothioate). Traces of fensulfothion sulfone were found in rutabagas (Brassica napobrassica Mill.) grown on fensulfothion-treated field plots, but were confined, for the most part, to the peel. The sulfone was detected in carrots at 0.10 ppm on a fresh weight basis. Fensulfothion sulfone persisted in frozen carrots (Daucus carota var. sativa DC.) during a storage period of 4 yr. A simplified gas–liquid chromatographic procedure for the determination of fensulfothion and some of its metabolic products is described.
