Pesticide residues in soil in Olericulture based land use systems in different Agro-climatic zones of Himachal Pradesh
Author(s): Sukh Pal Singh Brar and ID Sharma
Abstract: The soils were collected from different fields with intensive vegetable crop producing land use systems and uncultivated fields, from four agroclimatic zones of Himachal Pradesh viz., 1) sub tropical sub montane and low hills 2) temperate sub-humid mid-hills 3) wet temperate and high hills 4) dry temperate high hills cold desert, and pesticide residue study was carried out in Toxicology Laboratory, Department of Entomology and Apiculture, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, India. More than 90 per cent soil samples analysed from different zones of the state have shown presence of various pesticide residues viz., DDT, HCH, endosulfan, chlorpyrifos, pyrethroids, dicofol and chlorothalonil. The orchard soils intercropped with cereals also showed the presence of HCH, DDT, endosulfan and dicofol residues. It can be concluded that the most common insecticide residues in Himachal soils are DDT, HCH, endosulfan, chlorpyrifos, dicofol, pyrethroids and chlorothalonil in the order of decreasing contamination. In vegetable soils, especially in cabbage, DDT was the major contaminant followed by endosulfan and dicofol. The tomato soils showed variably much higher concentration of HCH isomers as compared to its corresponding level in cabbage soils.
