Prospects of development of ecological methods of potato protection from diseases and pests

The article presents data on the prospects of development of the main directions of environmentally safe protection of potatoes from diseases and pests. The results of studies of methods of environmental protection of potatoes, including crop rotations, sustainable varieties, optimal predecessors, pre-seed preparation, the use of growth regulators, agrochemicals and biological products. Application of short-rotation crop rotations with 25% potato saturation in the following crop rotation: 1) barley - (oats+peas) - winter wheat-potatoes; 2) (barley+clover) - clover of the 1st year of use-clover of the 2nd year of use - potatoes. reduces the number of tubers for Rhizoctonia to 2 times, and scab - 3.6 times. Variants of these rotations increase the number of species of beneficial entomofauna in 1.6 times in comparison with the permanent culture of potatoes. The row spacing of 90 cm provided an increase in the gross yield of 6.3 t/ha compared to the standard (70 cm). The positive influence of Atonik Plus drugs, Mival agro, Albite, Carefin at reducing the incidence and severity of black scurf, early blight, late blight, dry and wet rots of potato in the growing period and after the silo. The biological effectiveness of the drug Verticillin in the fight against aphids in the conditions of gauze-film insulators (tunnels). According to the data this figure is an average of 98.0-98.9% of and almost not inferior to the efficiency of a chemical preparation of BI-58 New (of 98.4-99.1% of). According to the results of the evaluation revealed a complex field resistance to major pathogens from the following domestic and foreign varieties of all maturity groups: Arosa, an Athlete, a delicacy in Bryansk, Bryansk reliable, Giant, Vitesse, Blue, Elizabeth, crane, Innovator, Bun, Kuznechanka, Lugovskoy, Lyubava, Lady Rosetta, Hope, nikulinskaya, Victory, Pogarsky, Resource, Rosary, Russian souvenir, Santana, Sokol, Spiridon, Tulevski, Luck, Duck, Fritella, Magician, Anniversary Zhukov, Effect. The studied environmentally safe methods of protection of potatoes from diseases and pests are the preparatory stage for the organic cultivation of this crop in the Russian Federation
