DISEASES OF СACTACEAE JUSS. FAMILY REPRESENTATIVES IN THE NIKITSKY BOTANICAL GARDEN COLLECTION

Studies conducted in the Nikitsky Botanical Garden, where the collection of Cactaceae Juss. family is located, showed that the overwhelming majority of the species composition of the pathogenic mycobiota that causes diseases manifestations in plants belong to the fungi of the genus Fusarium Link and Plectosphaerella Kleb. Representatives of five genera – Acanthocalycium Backeberg, Astrophytum Lem, Cereus Mill, Echinopsis Zucc, Ferocactus Britton & Rose showed the highest susceptibility to phytomycosis. The combined use of three biopreparations «Nikfan F», «Nematophagin» and «Respect» in protected soil reduced cacti susceptibility of diseases in the greenhouse by 37,0 % and significantly improved the ornamental appearance of the plants
