The residue and dissipation studies of diafenthiuron, its metabolites and cyantraniliprole were carried out on okra under field conditions after two applications of Cyantraniliprole 7.3% w/w + Diafenthiuron 36.4% w/w SC @ 60 + 300 g a.i./ha. Okra fruit samples were collected at 0 (2 hr), 1, 3, 5, 7, 10 and 15 days after second spray. The samples were processed using QuEChERS methodology and analysed on LCMS/MS. The total initial residues of diafenthiuron (diafenthiuron + CGA 177960, CGA 227352, CGA 140408) in okra fruit were 0.28 and 0.55 mg kg−1 at single and double dose, respectively. The total residues of diafenthiuron dissipated below limit of quantification (LOQ) of 0.01 mg kg−1 at 10 days of application at both the doses. The initial residues of cyantraniliprole in okra were 0.23 and 0.42 mg kg−1 at single and double dose, respectively. The residues dissipated below −1 at 7 and 10 days in both the dosages. For safe consumption of okra, waiting period of 10 days is suggested. [ABSTRACT FROM AUTHOR] |
