Mycobiota of the rhizosphere of raspberry plants (Rubus idaeus L.) under the influence of varieties and new fertilizers in conditions of organic production

Abstract

The results of studies of influence of raspberry plant varieties and new organic fertilizers on the abundance and species composition of the micromycetes in rhizospheric soil in conditions of organic production are presented. The mycobiota of Joan J and Himbo-Top raspberry varieties during plant ontogeny was analyzed and the species composition of phytopathogenic micromycetes, which are presented in the rhizospheric plant soil, was defined. It was revealed that the following fungi species prevail in the population: Botrytis cinerea, Pers, Aspergillus niger, V. Tiegh, Alternaria alternata, (Fr.) Keissl, Fusarium sp. These fungi are producers of mycotoxins that can cause dangerous diseases in animals and humans. There is a stabilizing selection of microorganisms in the phase of separation of buds in inflorescences in the mycobiota of the rhizosphere of plants of raspberry varieties under the influence of the organic fertilizer VITERI with the addition of Basil essential oil
