Abstract

This article highlights the economic importance of potato and one of its most harmful diseases – late blight (Phytophthora infestans d By, Oomycetes, Peronosporales), describing its development conditions and control measures. The disease may reduce potato yield by up to 30–70% due to leaf, stem, and tuber damage. The main objective of the study was to evaluate the efficacy of Pervatin 72.2% s.e., a fungicide produced by “AGRIMATCO GENERAL” LLC in Uzbekistan. Pathogen identification was carried out using the method of M.K. Khokhryakov (1980), and biological efficacy was calculated according to Abbott (1925). The results showed that Pervatin 72.2% s.e. demonstrated 71.4–89.1% biological efficacy, which was comparable to or even higher than the standard fungicide Prevent 72.2 s.e.c.
