Abstract

The main objective of this study was to understand the residue and persistence behavior of lufenuron insecticide in grape fruit samples. The residues were analyzed by HPLC and it dissipated in grape fruit following first order kinetics. The average initial deposit of in grape fruit was observed to be 1.85mg kg-1 at single application rate. The recoveries of lufenuron on grape fruit were observed from 91.97% to 95.25% at fortification levels of 0.1, 0.5 and 1.0mg kg-1. The reported limit of quantification (LOQ) was found to be 0.01mg kg-1. The dissipation experiments showed the half-lives (T1/2) of lufenuron were around 2.79 days. According to the maximum residue limit (MRL) the pre-harvest interval (PHI) of lufenuron on grape was 3 days after the treatment.
