Pathomplex of micromycetes on the outland part of raspberry red in Moscow region

Abstract

Studies conducted in the Moscow region in 20142018 showed that the pathocomplex of micromycetes on raspberry stems includes about 55 species, of which the main stem pathogens are Coniothirium fuskelii (Leptosphaeria coniothyrium), Phoma idaei (Didymella applanata), and Colletotrichum rubicola. There was a decrease in the prevalence of P. idaei and C. rubicola on remontant raspberry varieties, which is associated with the technology of their cultivation. The main part of the micromycetes pathocomplex on raspberry berries in two areas was occupied by the fungi Botrytis cinerea and Cladosporium cladosporioides, they were associated with the rot of the berries. In the pathocomplex of micromycetes, Alternaria tenuissima and C. cladosporioides species prevailed on raspberry leaves. In addition, it includes fungi - pathogens of raspberry leaf spots, such as Phragmidium rub-idaei, Pyrenochaeta rubi-idaei, Phyllosticta fusco-zonata, Septoria rubi.
