Dissipation Kinetics of Propargite in Brinjal Fruits Under Subtropical Conditions of Punjab, India

Abstract

Residues of propargite were estimated in brinjal fruits by High Performance Liquid Chromatography (HPLC) following single application of Omite 57 EC @ 570 and 1140 g a.i./ha. The average initial deposits of propargite were observed to be 0.51 and 0.92 mg/kg, respectively, which were below its maximum residue limit (MRL) of 2 mg/kg. The residue levels of propargite dissipated below limit of quantification (LOQ) of 0.02 mg/kg after 10 days at both the dosages. The half-life values (T1/2) of propargite were worked out to be 3.07 and 3.54 days, respectively, at recommended and double the recommended dosages. A waiting period of one day has been suggested for the safe consumption of brinjal fruits to avoid any health hazards.
