Abstract
The article studies phomoid fungal pathogens associated with growing potatoes in Moscow Oblast and Leningrad Oblast identified in the period 2019–2020. Biological characteristics of pycnidial fungi and peculiarities of infestation symptom are presented, diagnostically significant cultural and morphological characters are described. As a result of the research, representatives of the genera Didymella, Neoascochyta, Phoma, Boeremia were identified from pycnidial fungi on diseased potato leaves. During the growing season, the dominant position among non-pycnidial fungi in 80% of the studied samples taken in Moscow Oblast was formed by species of the genus Alternaria. The fungus Boeremia foveata (Foister) Aveskamp, Gruyter & Verkley was isolated in a single case during a survey of potato plantings in the Pushkin district of St. Petersburg. The studied plants also contained species uncharacteristic for potatoes: from the affected leaves, the species Neoascochyta exitialis (Morini) Q. Chen & L. Cai и Didymella pinodella (L.K. Jones) Q. Chen & L. Cai were isolated once. As a result of the research, 10 species of phomoid pathogenic fungi were isolated and identified. The obtained isolates were deposited in the mycological collection of the FGBU “VNIIKR” to study the morphological features of the complex of potato micromycetes, the presence of which is possible together with quarantine pests.
