Abstract : The dissipation of carbaryl and monocrotophos residues was studied on mango fruits. Following treatment with 0.05, 0.1 and 0.2%, initial carbaryl deposits of 15.95-50.77 p.p.m. on unripe mangoes and 15.73-50.73 p.p.m. on ripe mangoes were dissipated by 96.03-100 and 96.23-100%, resp., 15 days after treatment. The half life varied from 2.4 to 6.78 days. Spraying with monocrotophos at 0.05, 0.075 and 0.1% resulted in residues of 0.95-2.6 p.p.m. on fruits which degraded by 72.83-79.68% within 20 days on unripe fruits and by 100% on ripe fruits.
