Shulga O. Green mold pathogens (Trichoderma spp.) of medicinal edible mushrooms shii-take /Lentinula edodes (Berk.) Pegl./ and biological bases of limited measures of their development.

Object of research - Fungi of genus Trichoderma - green mold pathogens of shiitake; strains of edible medicinal mushroom shiitake (Lentinula edodes).Purpose - to investigate distribution and harmfulness of green mold and also to find ways of limitation their development under the conditions of industrial cultivation of edible mushroom shiitake. Methods - mycological, phytopathological, molecular-biological and statistical. Novelty - distribution and development of green mold on the mushroom shii-take is firstly investigated and also biological and ecological features of its pathogens were studied. The main pathogens of green mold are the Trichoderma species, among which T. harzianum is the most distributed and harmfulness. The interaction between green mold pathogens (Trichoderma spp.) and shii-take strains (Lentinula edodes) was firstly examined. The main types of interaction in pure cultures were defined. The pathogenic activity of Trichoderma spp. depends on temperature and strain characteristics. Green mold resistance of different shii-take strains was estimated. High yield and green mold resistance strains of Lentinula edodes such as Reef and Admiral were bred. The impact of major elements of industrial shii-take production upon competitive ability to the pathogens of green mold was studied. It was explored in vitro the influence of fungicides on growth and development of Trichoderma harzianum and L. edodes.Results of researches - can be used in practice, educational process and research work. Field - mushroom industry (agriculture).
