The article provides data on alfalfa diseases in the Tashkent region of Uzbekistan. During the study, 23 alfalfa pathogens were identified, and the species composition of the noted mycobiota is given. The most common and harmful diseases have been identified, which include various spotting, downy mildew, powdery mildew, rust, wilting and root rot. The number of the group of obligate parasites is 13%, facultative saprotrophs — 56% and facultative parasites — 30% of the total number of identified mycobiota.
The issue of the presence of micromycetes that cause diseases of caterpillars of one of the most dangerous pests of Gossypium — Helicoverpa armigera (Hübner, 1808), is discussed. In 2020-2021 20 species of micromycetes were identified and isolated in a pure culture. These cultures artificially infected 50 wax moth caterpillars. As a result, only 2-4% of dead caterpillars were noted. These strains of fungi are pathogens and have entomopathogenic properties but are of no practical interest.
