| Popis: | The article presents data from a long-term phytopathological survey of a collection of varieties Iris x hybrida Hort. Main Botanical Garden named after N.V. Tsitsin RAS (Moscow). Data on diseases of bearded irises in the urban environment were obtained, changes in the composition of the fungal complex in the rhizo- and phyllosphere were studied. Low soil fertility during the adaptation period of bearded irises worsens the formation and development of the root system of plants, increases the likelihood of increased disease damage and premature leaf fall. The experience of successful establishment of cultivators Iris x hybrida with the use of complex preventive and health-improving measures to improve fertility and reduce stress factors has been obtained. It was found that the introduction of NPK-complex, etching with a biofungicide based on phytobacteriomycin, and spraying vegetative plants with a microbiological preparation based on saprophytic antagonist fungi and bacteria within two years from the moment of transplanting varieties of garden bearded irises have a positive effect on their survival rate and decorative effect. The use of biological fungicides in combination with a complex of fertilizers is mandatory in a pesticide-free protection system for garden iris varieties sensitive to mycoses. |
