Soil in comparison with other objects in the human habitat, is the place of maximum pesticide accumulation. Soil is a link in the biosphere that is both the start and the end of many migration routes of xenobiotics along the soil-water-air and food chains. Therefore, it is necessary to strictly control the xenobiotic content of soil as an additional criterion for the degree of contamination of adjacent environments at acceptable levels. The purpose of the present experimental study was to investigate the migration-water hazard indicator of a benzoylurea derivative pesticide active ingredient and its formulation and to establish an evidence-supported threshold concentration for the pesticide in soil according to this hazard indicator. The migration-water hazard indicator characterizes the processes of pesticide migration from soil to groundwater. The study was conducted under the standard and comparable soil and microclimatic conditions using a soil model standard and special laboratory filtration units. The method of laboratory modeling is a mandatory step in the study of the migration of pesticides in soil.
