Abstract: Field trial was conducted to study the dissipation pattern of triazophos in/on brinjal by following two foliar applications at recommended (500 g a.i./ha) and double the recommended dose (1000 g a.i./ha) at fruit initiation stage. The brinjal crop was sprayed twice at 10 days interval. Initial residues of triazophos in brinjal fruits were recorded as 0.90 and 1.85 mg kg^-1 on brinjal fruits with the half life of 2.10 and 2.04 days at recommended and double recommended dose, respectively. The residues of triazophos reached below quantification limit (BQL) after 7 and 10 days in both the doses. Considering this, Pre-Harvest Interval (PHI) of seven days can be suggested for triazophos for residue free brinjal.
