Field experiment was conducted to study the dissipation kinetics of acephate in citrus fruit. The acephate @ 560 g a.i/ha applied three times at an interval of 10 days initiating at fruit formation stage. The The citrus fruit samples were collected at an interval of zero hours, 1,3,5,7,10, 15 and 20 days after last application and citrus juice, soil at harvest. The collected citrus fruit samples were analysed by QuEChERS method after validations. The initial deposits recorded 0.414 mgkg-1 and same dissipated to Below Detectable level 15 days after last spray. The waiting period was calculated 13.16 days safe consumption of citrus fruit after last application. The citrus juice and soil at harvest were not detected acephate residues and are below detectable levels.
