The dissipation pattern of phosphamidon residues in Indian mustard (Brassica juncea L. Czern and Coss) has been studied along with its effect on the changes of chlorophyll, sugar, starch, oil and some fatty acids and minerals. The safe waiting period was calculated to be 12.56 days for 0.03% and 15.19 days for 0.05% in green foliage; the corresponding values in green pods were 12.50 and 15.30 days. For both the doses, the T 1/2 were 3.34 days in green foliage and 3.58 and 3.86 days in green pods. The chlorophyll content was lowered after the application of phosphamidon but increased with dissipation of the pesticide. The carbohydrate was lowered whereas the oil contents were greatly increased in the treated seeds. The individual fatty acids did not differ much albeit the erucic acids in treated seeds were found to be higher than the control.
