The researches were done in the dynamics by using the pesticides of different phytosanitary purpose, such as fungicides and insecticides. As a result of researches the necessity of strict observation the recommended time of application, rates and number of treatments for getting the yield free of applied pesticide active ingredient residues content is determined considering the fact that the given production is raw used without heat treatment
