Abstract:

Four months after granular fensulfothion was banded at various rates 3 cm below the surface of a fine sandy loam soil, residues of the parent material (f) were ca. 2.5 times higher than those of its oxidation metabolite, fensulfothion sulfone (fs). The same relative concentrations of f and fs were present in mature carrots grown in the treated soil. However, in rutabagas, residues of fs were more than 3 times higher than the parent f. After fall cultivation by rototilling the rows 15 cm deep and mixing the insecticide into the soil, carrots and rutabagas were planted in the same treated soil the following year. Residues remaining in the soil (after 16 months) comprised ca. 3 times more fs than f. Carrots again contained the same relative ratios of residues as the treated soil, but totals of f and fs at all rates of application were higher in the 2nd year's crop than in that grown the previous year. In the 2nd year's rutabaga crop, low levels of fs and only traces of f were detected, even in plots where excessively high rates (up to 34 kg active/hal had been applied the previous year.
