An analytical method for the quantitative determination of meptyldinocap (2,4-DNOPC) as 2,4-dinitrooctylphenyl (2,4-DNOP) in mango and soil was developed as well as validated using liquid chromatography tandem mass spectrometry (LC-MS/MS). The method comprised an extraction with an acetone:methanol:4 N HCl (100:10:5, v/v/v) mixture followed by hydrolytic(More)
A rapid, specific, and sensitive multiresidue method to determine 67 pesticides in made tea, tea infusion, and spent leaves was developed and validated for routine analysis by GC/MS with an approximately 29 min GC run time. The method was reproducible (HorRat < 0.5 at 50 ng/g) when validated at 50 and 100 ng/g. The samples were extracted with ethyl(More)
A rapid, specific and sensitive multiresidue method to determine 42 pesticides in made tea, tea infusion and spent leaves has been developed and validated for the routine analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The method was reproducible (Horwitz ratio (HorRat) <0.5 at 50 ng/g) and validated by the analysis of sample spiked(More)
The photolysis of a rice herbicide Bispyribac sodium (Sodium 2, 6-bis [(4, 6-dimethoxypyrimidin-2-yl) oxy] benzoate) has been studied in different aqueous medium (distilled water, pond water and Irrigation water) under the influence of UV (lambda max > or = 250 nm) and sunlight in presence or absence of sensitizers (TiO(2) and KNO(3)). The study was(More)
A multi-location field trial was conducted under North-East Indian climatic condition viz. Siliguri and Dooars, West Bengal, India during Monsoon 2005 to evaluate the dissipation pattern of Milbemectin formulation (Milbeknock 1% EC) in/on tea field at two application rates (5 and 10 g a.i. ha(-1)). The quantitative analysis was performed using High(More)
