The effect of different Trichoderma species on the yield of Agaricus bisporus strains was investigated in this study. For the first time, the effect of different Trichoderma species on the yield of Agaricus bisporus strains was determined under fully controlled conditions. Four button mushroom strains were used: Somycel 53, Somycel 11, Amycel 2200, and Polmycel 31. The cultivation substrate was inoculated...
Fungi of the genus Trichoderma are a very large group of microorganisms that play a significant role in the environment. They use a variety of mechanisms to colonise various ecological niches. Several Trichoderma spp. positively affect plants by stimulating plant growth, and protecting plants from fungal and bacterial pathogens. They are used in biological plant protection as biofungicides as well...
The influence of substrate infestation with Trichoderma pleurotum and T. pleuroticola isolates on yielding of two commercial strains of Pleurotus ostreatus was investigated. The examined P. ostreatus strains growing on substrates infested with Trichoderma isolates showed a considerable yield decline. T. pleuroticola isolates were found to exert a greater unfavorable impact on P. ostreatus yields than...
Growth of Trichoderma pleurotum and T. pleuroticola isolates on the Potato Dextrose Agar (PDA) medium was investigated. T. pleuroticola isolates showed a significantly greater diameter of their mycelium colonies after 5 days of incubation than the T. pleurotum isolates. In addition, biotic interactions between T. pleurotum and T. pleuroticola isolates and species of Pleurotus sp. were determined....
The impact of different isolates of three species of the Trichoderma genus on the development of wild strains of Coprinus comatus mycelium was investigated. Nine strains of C. comatus obtained from natural sites and one cultivated strain were used in the trail. The following Trichoderma isolates were used: T. aggressivum f. europaeum, T. longibrachiatum and T. atroviride. It was found that isolates...
The research project aimed at determining the effect of incubation temperature and pH of the agar medium on the mycelium growth of Mycogone perniciosa (Magnus) Delacroix and Verticillium fungicola (Preuss) Hassebrauk in in vitro conditions. Ten M. perniciosa and ten V. fungicola isolates were applied. Mycelium growth of the above-mentioned isolates was studied on PDA agar medium (Merck) enriched with...
The impact of infestation with Trichoderma aggressivum f. europeanum and Trichoderma longibrachiatum isolates on the yielding of three wild strains and one cultivated strain of Coprinus comatus was investigated. A significant yield reduction of C. comatus on substrates infested with the examined Trichoderma isolates was determined. The recorded percentage yield reduction was significantly higher in...
The effect of infections with Trichoderma aggressivum f. europaeum on the yielding of seven wild and one commercial strain of Agaricus bisporus (Lange) Imbach. was investigated. Wild strains of the mushroom were derived from natural habitats of Poland. The cultivation substrate was inoculated with two different isolates of T. aggressivum f. europaeum Th2. It was found that infections of the substrate...
