Abstract : The rate of degradation of monocrotophos in mango fruits and penetration into pulp was studied during storage. Initial deposits ranging from 7.15 to 12.71 p.p.m. were recorded on the skin of unripe fruits, and dissipated by 95.16-96.20% within 20 days of treatment. The half life values were 3.72-4.56 days. Penetration of such residues from the skin to the pulp was below the tolerance level. Deposits of 7.01-13.06 p.p.m. on the skin of ripe mangoes dissipated by 100% within 15-20 days. Half life values varied from 3.34 to 4.8 days. Penetration of residues from the skin to the pulp was below the tolerance level for both unripe and ripe fruit.
