Protection of potatoes from late blight in Sakhalin
Abstract The article presents long-term studies on the study of agrotechnical and chemical measures to combat potato late blight in the Sakhalin region. At the initial stage of work (1951-1966), the local population of the fungus Phytophtora infestans was studied, and a method for short-term prognos...

In 1996-2003 among the studied modern fungicides, the most effective were systemic preparations (Acrobat MC, Ordan), as well as the combined use of Ordan with the biological product Planriz and Sodium Humate, which made it possible to reduce the development of the disease by 24.2-69.1% and increase the yield by 17.3-48.9%. According to the results of research in 2016-2019. Innovative combined action fungicides Infinito and Consento had the maximum protective effect against fungal infection. The use of drugs under production conditions made it possible to reduce the degree of damage to the vegetative mass by the pathogen by 56.5-60.0%, and increase the yield by 31.2-36.5%. Technical efficiency corresponded to 67-71%. The studied biopreparations (Trichocin, Vitaplan) are recommended for prophylactic treatment of potatoes in the initial period of vegetation.
