DETERMINATION OF ORGANOCHLORINE INSECTICIDE RESIDUES IN DIFFERENT TYPES OF SOIL, WATER AND PLANTS OF ZARAFSHAN VALLEY

In the soil conditions of the Zarafshan Valley in the composition of organochlorine pesticides HCH with isomers prevailed, in which lindane took a substantial amount, this reflected the weak destruction of insecticides. Pesticide contamination of waste, groundwater and drinking water is defined. It was found that on a background of 20 t ha-1manure ecological condition of the soil is improved by more than 2 times, a double dose of prometrin on a background of 20 t ha -1of manure improves soil productivity by 59-31%, after 3-4 months a positive effect falls off sharply. The biggest takeaway of HCH isomers by plant organs was observed in the treatment with the use of HCH and the use of 20 t ha -1of manure. The highest uptake of HCH was observed in the treatment with earthworms, tree leaves and manure 20 t ha -1.
