title: Dissipation kinetics of metalaxyl in cucumber.
abstract: Residues of metalaxyl were estimated in cucumber fruits using Gas Liquid Chromatography (GLC) with Nitrogen phosphorus detector (NPD). Following three applications of Ridomil-MZ @ 0.3% and 0.6%, the average initial deposits of metalaxyl were observed to be 0.19 and 0.24 mg kg(-1), respectively. The residues dissipated below the limit of quantification (LOQ) of 0.02 mg kg(-1) after 10 days at both the dosages. The half-life values (T(1/2)) of metalaxyl was worked out to be 3.5 and 3.0 days, respectively at 0.3% and 0.6% concentration. Thus, a waiting period of 1 day was suggested for the safe consumption of metalaxyl treated cucumber.
