Gavrylyuk L. Monitoring for pesticides in sugar beet agro-cenosis.

Systemic analysis for pesticides which are used in sugar beet growing was first made. Insecticides, fun-gicides and herbicides were objects of this study. The aim of the study consisted in ecotoxicological grounding and evaluation of a risk at usage of pesti-cides which were applyed widely at sugar beet growing in the forest-steppe zone of Ukraine. There were applyed the contemporary methods of physical and chemical analysis, namely: thin-layer chromatog-raphy, gas chromatography with application of the devices "Tsvet-106" and "Perkin-Elmer-8410". Algo-rithm of determination for different in polar pesti-cides in plants and in the soil was developed. The tree methodical recommendations developed by an algorithm affirmed by the State Commition on Chemical Preparations of Ukraine as official ones. It permits to model the method for determination of pesticides in terms of their dipol moments without complicated experiment. The modified models for forecasting and evaluation of pollution with pesti-cides th e sugar beet agrocenosis were developed. It was determined the level for safe usage of pesticiles in sugar beet fields in the comditions of the Forest - Steppe zone of Ukraine. It was proved that rational use of pesticides in sugar beet protection don't cause the pollution of environment.
