Degradation Dynamics of Chlorfenapyr Residue in Chili, Cabbage and Soil

Abstract

Chlorfenapyr is a pyrrole group of insecticide, [4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethyl-1H-pyrrole-3-carbonitrile]used as broad spectrum insecticide/acaricide to control whitefly, thrips, caterpillars, mites, leafminers, aphids, etc., chlorfenapyr 10% SC formulation was applied on chili and cabbage twice @ 75 and 100 g a.i./ha along with untreated control. Chlorfenapyr was dissipated in chili, cabbage and soil following the first-order kinetics (logC/C 0 = −kt). The half lives of chlorfenapyr in chili, cabbage and soil were varying from 2.93 to 2.96 days, 2.98 to 3.62 days and 4.06 to 4.36 days respectively, according to the application rate.
