Аннотация:Abstract: Researches indicate that the application rate of the pestiсide does not correspond to the threshold limit value (maximal allowed concentration) for 31% active substance (a.s.) implemented in RF. In our view, it may be related to the methodical errors in experiments with soil. We propose to use the application rate of the pesticide, recalculated in mg of a.s./ kg of soil as a standard to control pesticides in soil in RF.
