Dissipation studies of triazophos in/on polyhouse grown capsicum and cropped soil

PN Guru and CS Patil

The dissipation pattern and to recommend the Pre Harvest Interval (PHI) of triazophos in/on capsicum was studied after application of insecticide at fruit initiation stage. Triazophos @ 500 and 1000 g a.i. ha-1 was applied twice at an interval of 10 days. The initial residues deposit was 3.17 and 6.13 mg kg-1 respectively, and it was dissipated according to first order kinetics at both the dosages to Below Quantification Limit (BQL) at 20th and 25th day, respectively @ 500 and 1000 g a.i. ha-1. The half-life recorded was 2.95 and 2.63, respectively at recommended and double the recommended dose, respectively, whereas the cropped soil leaves with no residues. Considering the LOQ of 0.05 mg kg-1, Pre-Harvest Interval (PHI) of twenty days can be suggested for triazophos for safe consumption of capsicum fruits grown under polyhouse.
