title: 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 (T(1/2)) 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.
