Micromycetes on winter wheat in the Krasnodar territory and Rostov region
A range of pathogenic and saprophytic fungi developing on winter wheat in 2019 in the Krasnodar territory and the Rostov region has been established. Winter wheat plants with various signs of fungal infection on the leaves and roots were used as research material. In total, about 50 species of micromycetes were isolated and identified from wheat samples. In the autumn-winter period a complex of micromycetes with different trophic specialization was formed in the wheat cenosis. Among them, hemibiotrophes from the genera Bipolaris, Fusarium, Alternaria and obligate parasites from the genera Erysiphe, Puccinia were noted on the leaves. Species of the genera Aspergillus, Penicillium, Mucor, Botrytis, Acremonium, Cladosporium, Verticillium, Trichotecium, and others were assigned to the group of saprotrophic fungi that were mainly found in the rhizosphere of winter wheat.
