Abstract

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.
