ABSTRACT
Residues of ethion were estimated in cucumber by gas liquid chromatography following three applications of the insecticide at 375 and 750 g a.i ha(-1). The average initial deposits of ethion on cucumber fruits were found to be 2.40 and 4.97 mg kg(-1) at single and double dosages, respectively. Residues of ethion dissipated below the maximum residue limit (MRL) of 0.5 mg kg(-1) in 7 days. Half-life (T1/2) for degradation of ethion on cucumber was observed to be 2.92 days at recommended dosage. A waiting period of 7 days is suggested for safe consumption of cucumber.
