THE INFLUENCE OF BIOPREPARATIONS AND SYNTHETIC FUNGICIDES ON GROWTH ON MICORRHIZAL FUNGUS Oidiodendron sp. IN VITRO

500 SC was examined on the growth of micorrhizal fungus Oidiodendron sp. Fungicides were added to PDA medium at the following concentrations: recommended dose, 5-times lower than the recommended and 5-times higher than the recommended. The synthetic fungicides were more toxic to Oidiodendron sp. than biopreparations. On the medium containing Horizon 250 EW fungus did not growth. The greather part of biopreparations inhibited growth of Oidiodendron sp. but only Bioczos SL and Propolis in dose 5-times higher than the recommended, toataly inhibited growth of fungus colonies
