New pathogens of fruit plant shoots in Poland

The studies conducted in the years 2010-2012 showed that among the fungi species inhabiting shoots of fruit plants there were cultures of Phomopsis spp. They were isolated mainly from the shoots originated from orchards without chemical protection. Moreover, isolates of Phomopsis obtained both from shoots with disease symptoms and from visually healthy ones. The morphological characteristics of isolated strains and their pathogenic abilities as well as genetic similarity suggest that they represent one species of fungus.
