Potatoes comprise a strategically important food crop in the Russian Federation. Enhanced chemicalization of potato production, while protecting it from pests and diseases, allows you to get high yields, but at the same time significantly affects the biological quality of products. The retail chain often receives lots of tubers with excess nitrates, while containing the so-called "long-playing" pesticides. Getting into the human body with products, toxic substances cause severe diseases. There is an acute problem of providing children with environmentally friendly products. This research developed an important task of neutralizing the accumulation of toxic insecticides and fungicides in tubers by the beginning of harvesting when cultivating medium-early varieties of potatoes. This was achieved when using the insecticide Celest TOP (Thiamethoxam, hazard class 2) in reduced by 25% norms, in combination with the use of biological preparations Siliplant or Albit and reduced by 40% norms of fungicides. The protection system included for tubers: Celestine 0.3 L/ha + Albite TPS 0.1 L/t. For tops: Ridomil gold MC VDG 1.5 kg/ha first, second and third treatments. Shirlan SK 0.24 L/ha 4-5-th treatment + Albit TPS 2 times for vegetation 0.05 L/ ha or Siliplant BP 2 times for vegetation 1.0 L/ha. Laboratory analyses revealed residual amounts of pesticides and nitrates in tubers. The resulting products, with the plant protection system developed by us, meet the requirements for children's and dietary nutrition. The inversion voltammetric method was used to determine the concentration of pesticides in tubers. Nitrates were determined using an ion-selective electrode. It is established that Prestige (Imidacloprid, hazard class 1) is impractical to use in producing ecologically clean potatoes. Using Celest (Thiamethoxam, hazard class 2) in combination with Albit or Siliplant increased the yield and reduced the content of toxic substances in tubers.
