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

The results of research on the influence of foliar treatment of raspberry plants with organic fertilizer VITERI on the population size and species composition of micromycetes in the mycobiome of the rhizosphere and vegetative organs of raspberry plants of Joan J in the Central Forest-Steppe of Ukraine are presented. Microbiological, phytopathological, mycological methods and methods of sampling of raspberry plants during the growing season were used for the study. To determine the effect of VITERI fertilizer on the mycobiota of the rhizosphere and vegetative organs of raspberry plants during plant ontogeny, additional foliar treatment was performed with 1% aqueous solution of VITERI fertilizer. It was found that the population is dominated by fungi of following species: Septoria rubi, West, Aspergillus niger, V. Tiegh, Alternaria alternata, (Fr.) Keissl, Fusarium spp. These micromycetes are producers of mycotoxins and can cause disease in animals and humans, as well as contribute to biological contamination of agroecosystems. During foliar treatment of raspberry plants with VITERI fertilizer, a significant decrease in phytopathogenic load was observed in the phase of intensive fruiting compared to other phases of ontogenesis of raspberry plants.
