Preplanting dressing tubers of varieties Arkhideya and Vytok by fungicides vitavask 200FF and ditan М-45 in mix with insecticide gaucho reduced prevalence of rhizoctoniosis on sprouts on 64,2-80,7%, degree of development of the given illness on 83,9-87,7% and raised productivity of potato on 3.6-8,8 t/he. Use of desinfectant Gaucho in structure of insecticide promoted destruction of adult individuals and larvae of 1-3 age of Leptinotarsa decemlineata (Colorado beetle) and to reduction of quantity of tubers affected by Elateridae on 55,0-68,3%. Processing of seed tubers by insecticides aktara and krujzer and under production conditions reduced number of larvae of Leptinotarsa decemlineata on 88,5-96,7%. At complex processing of seed tubers of potato variety Neptun, Briz, Talisman, Dubrava, and Zhuravinka by pesticides and microcells it is marked that varieties of potato of different groups of ripeness unequally react to complex processing of seed tubers. The crop increase thus depends on concrete variant. Processing of seed tubers by prestige reduced affection of sprouts of potato by Elateridae on 71,3-74.3%, local bazudin application - on 58,7-70,2% and soil processing at dursban hilling - on 36,9-56,8%
