Abstract

One field experiment was conducted with lufenuron (Match(®) 5% EC) on tomato crop during August 2011. The main objective was to understand the residue and dissipation behavior of insecticide lufenuron in tomato fruit samples. The dissipation behavior of lufenuron insecticide followed first-order rate kinetics at standard recommended dose application. The average initial deposit of lufenuron in tomato was observed to be 1.299 mg kg(-1)at single application rate. This lufenuron residue dissipated to bellow LOQ of 0.03 mg kg(-1) 21 days after the treatment. Lufenuron residues were lost with pre-harvest intervals of 7 days, following application at the recommended dose by manufacture.
