Fruit samples of ber, grapes and guava analysed for pesticide residues employing multiresidue analysis by gas liquid chromatography equipped with ECD and NPD detectors and capillary columns showed contamination with organochlorine, synthetic pyrethroid and organophosphate insecticides. Among organochlorines, HCH, DDT and endosulfan were detected in almost(More)
Twelve samples each of soil and ground water were collected from paddy-wheat, paddy-cotton, sugarcane fields and tube wells from same or near by fields around Hisar, Haryana, India during 2002-2003 to monitor pesticide residues. Residues were estimated by GC-ECD and GC-NPD systems equipped with capillary columns for organochlorine, synthetic pyrethroid and(More)
Field study was carried out to investigate fate of fipronil (Regent 0.3G) in cotton and soil applied at the time of sowing of cotton crop (Variety: H-1117)@56 (T₁) and 112 g a.i.ha⁻¹ (T₂) during kharif season (summer season, from April to November) 2006-07. The residues of fipronil in both the doses dissipated almost completely with in 90 days. Kinetic(More)
Fipronil is a widely used insecticide with a well-described toxicological pathway. Recently it has been widely used in India to control vegetable pests. The present study has been carried out to observe the persistence pattern of fipronil and its metabolites-fipronil sulfone, fipronil sulfide, fipronil desulfinyl in cauliflower and soil so as to know the(More)
Persistence of chlorpyriphos in tomato was studied following applications of Action 505EC at 800 and 1600 g ha(-1) with active application of chlorpyriphos as 400 and 800 g a.i. ha(-1). The average initial deposits of chlorpyriphos were 0.155 and 0.372 mg kg(-1) on tomato fruits on application of ready-mix formulation, Action 505EC at single and double(More)
Butter (45) and ghee (55) samples were collected from rural and urban areas of cotton growing belt of Haryana and analysed for detecting the residues of organochlorine, synthetic pyrethroid and organophosphate insecticides. The estimation was carried out by using multi residue analytical technique employing GC-ECD and GC-NPD systems equipped with capillary(More)
Market samples (60) of six seasonal vegetables were monitored during 1996-1997 to determine the magnitude of pesticidal contamination. The estimation of insecticide residues representing four major chemical groups i.e. organochlorine, organophosphorous, synthetic pyrethroid and carbamate, was done by adopting a multiresidue analytical technique employing(More)
Monitoring of 80 winter vegetable samples during 1997-1998 for pesticidal contamination was carried out on GC-ECD and GC-NPD systems with capillary columns following multiresidue analytical technique. The tested samples were found 100% contaminated with low but measurable amounts of pesticide residues. Among the four major chemical groups, residue levels of(More)
The mobility of pendimethalin in sandy loam soil was studied in soil columns under laboratory conditions at two application rates, 1.0 and 2.0 kg a.i. ha(-1), with simulated rainfall of 300 mm. The maximum concentration of the herbicide was found in the top 10 cm layer, though it was found distributed in soil at all the depths at both the doses.
