The metabolic fate of diethofencarb (isopropyl 3, 4-diethoxycarbanilate) separately labeled with 14C at the phenyl ring and 2-position of the isopropyl moiety was studied in grape (Vitis vinifera L.). The acetonitrile solution of 14C-diethofencarb at a rate of 500 g ai ha-1 was once applied topically to fruits or leaves at the maturity stage of fruits (PHI 35 days), and the plants were grown in the greenhouse until harvest. In the grape plants, diethofencarb was ...
