  Ethyl-1-14C-prothiofos and some of its degradation products have been prepared for the present investigation. Cotton plants were treated with 14C-prohiofos alone and in presence of deltamethrin and dimilin pesticides under conditions simulating local agricultural practice. 14C-residues in seeds were determined at harvest time about 75% of 14C-activity was associated with oil. The ethanol soluble 14C-residues accounted for 6% of the total seed residues after further seeds extraction, while the cake contained about 18.5% of the total residues in case of prothiofos only. The bound residues increased in presence of deltamethrin and dimilin pesticides and amounted to 30% and 34% of the total residues, respectively. About 89% of the 14C-activity in the crude oil could be eliminated by simulated commercial processes locally used for oil refining. Chromatographic analysis of cotton oil extrac.. Read More»
