Abstract
Goal. The study of the effectiveness technology of potato cultivation for the phytosanitary state of tubers in the conditions of the Polesie region of Ukraine.
 Methods. Research of production crops of the Gabenets farm. Monitoring of major fungal diseases on potato tubers. Identification of phytopathogens on potato tubers. Farming technology consisted of 9 stages and included 6 herbicide-fungicidal treatments in the growing season of potato plants. Samples were collected and phytopathological analysis of potato tubers during harvest was conducted according to conventional methods. Identification of pathogens of fungal diseases was carried out at the Institute of Plant Protection of the National Academy of Sciences of Ukraine, according to conventional methods.
 Results. The performance of potato varieties in the application of a set of protection measures in FG “Gabenets” was evaluated. It was analyzed that the yields of varieties on the production crops of the farm were quite high and ranged from 50.25 to 58.10 t / ha, and the yield from one bush — from 1.014 kg to 1.163 kg. The highest yield was on production crops of the Pirol variety and amounted to 58.10 t / ha, compared to the control — 47.30 t / ha. Phytopathological analysis of potato chips varieties was carried out, which resulted in the detection of dry fusarium potato rot in control variants of Opal, Karlenа, Fantasia and Kibitz. No crop disease was detected in production crops where a system of protective measures was applied. Pirol cultivar has proven to be resistant to fungal pathogens.
 Conclusions. Protective measures during the vegetation of potato plants prevented the mass development of fungal diseases on potato tubers, which in turn will have a positive effect on the stickiness of the tubers and preserve their marketability.
