Abstract: Field trial was conducted to study the dissipation pattern of profenophos in/on tomato by following two foliar applications at recommended (500 g a.i/ha) and double the recommended dose (1000 g a.i/ha). The tomato crop was sprayed twice at 10 days interval at fruit initiation stage. Initial residues of profenophos in tomato fruits were recorded as 0.45 and 95 mg kg^-1 on tomato fruits with the half-life of 2.56 and 2.56 days at recommended and double recommended dose, respectively. The residues of profenophos 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 profenophos for residue free tomato.
