| dc.description.abstract | Dissipation and decontamination of chlorantraniliprole (Coragen 18.5% SC) in okra and soil (at harvest time) was studied following foliar spray on okra at recommended (30 g a.i. ha-1) and double of recommended (60 g a.i. ha-1) by Central Insecticide Board (CIB). The residue of the insecticide was analyzed using GC – MS/MS with a triple Quadruple analyzer, operated in the positive ion mode using multiple reaction monitoring (MRM) of the transitions m/z 278 > 249 and 278>251. Recovery experiment was performed on okra and soil sample fortified @ 0.01, 0.05 and 0.10 mg kg-1and the observed recoveries were in range 85.23 – 88.79 % and 84.65 – 88.65% respectively. The initial deposit of CAP residue in okra fruit was 0.077 and 0.140 mg kg-1 for single (T1) and double (T2) dose respectively. These residues dissipated following first order degradation kinetics with half -life 1.90 and 1.92 days and reached below quantified level (LOQ i.e 0.01 mg kg-1) on 7th and 10th day for single (T1) and double (T2) dose respectively. In soil (at harvest time) the residue level was < LOQ for both doses. The decontamination processes dislodges the chlorantraniliprole residue to the extent of 84.00 – 38.89% from okra fruits and washing followed by boiling was found more effective i.e. 84.00 % in dislodging residue of chlorantraniliprole than washing alone and unwashed conditions. | en_US |
