Abstract:
In the present study quinalphos and triazophos was applied twice @ 500 and 250 g a.i.ha
-1 separately on capsicum field to assess the dissipation behavior of two insecticides. Samples were collected periodically as per set schedule for residue analysis. Residues of these two insecticides were estimated on GC-MS/MS. The limit of quantification (LOQ) of quinalphos and triazophos was found to be 0.01 and 0.05 mg kg-1. Residues of quinalphos and triazophos reached below LOQ on 5
th and 7
th day after last spray. Dissipation behavior follows the first order kinetics with half-life (t1/2) 0.86 days and 1.43 days for quinalphos and triazophos, respectively.
