The article presents the results of the control of hawthorn plantations in the nut-fruit zone of the Burchmullinsky forestry enterprise, Bostanlyk district, Tashkent region in order to identify the most common hawthorn diseases. Phenological observations of the development of the identified diseases on different vegetative parts of hawthorn are described; 10 isolates of pathogens were isolated from 3 affected samples (leaves, stems, branches), among which fungi had the most predominant effects. Phytopathogenic fungi were identified using classical and modern methods: the fungus Gymnosporangium confusum Plowr. and the fungus Cylindrosporium oxyacanthae Iaca. Biologically active substances, biopesticides of microbial origin were used to eliminate the identified hawthorn diseases. Rust disease under the influence of biopreparations was suppressed from 83.3% to 92.5%, while brown spot was suppressed from 82.4% to 91.3%.
