METHOD OF PRODUCTION OF BIOLOGICAL PREPARATION FOR PROTECTION OF WINTER GRAIN CROPS FROM PINK SNOW MOULD Microdochium nivale

摘要

FIELD: agriculture.;SUBSTANCE: in the method the potato-dextrose agar (PDA) is prepared, the fungus is isolated in pure culture, the inoculum is prepared for infectious background, the nematodes (A. saprophillus) are isolated from the infected plants. The mycohelminths (A. saprophillus) are massively propagated on the fungus M. nivale at a temperature of +5°C. The suspension of mycohelminths A. saprophillus is prepared and applied in autumn on the fields affected by pink snow mould of winter grain crops, the suspension with the mycohelminths (A. saprophillus) at a dose of 160 thousand pcs/m².;EFFECT: method enables to reduce the number of fungicides used, destroys fungal mycelium of M. nivale of the pathogen PSM, promotes the plants to resist affected by PSM in the autumn-winter-spring period, provides obtaining the environmentally clean grain, and improves its quality.;3 tbl
