Abstract:
The global use of pesticides in agricultural and non-agricultural sectors has out-turned in the presence of mammoth residues in a variety of environmental commodities including plants, soil and water resources. Contamination of water takes place not only with the on-going use of agrochemicals but additionally due to leaching of persistent chemical ingredients from soil. A laboratory experiment was conducted during the year 2019, at CCS Haryana agricultural university, Hisar, Haryana in order to estimate the decline in levels of ready pre-mix formulation of Chlorantraniliprole + Thiomethoxam in canal water. Ready pre-mix formulation of Chlorantraniliprole + Thiomethoxam (Volium Flexi) was mixed in the canal water samples collected in amber bottles at the rate of 0.0375μg mL^-1 (SD) and 0.750μg mL^-1 (DD). Samples were collected on 0 (1 h), 3, 5, 7, 10, 20, 30, 45, 60 and 90 days after spiking. The technique of liquid-liquid partitioning with DCM (dichloromethane) was used for processing the collected water samples. Finally, the residues were estimated using GC MS/MS.
