A test of endophytic Bacillus subtilis 11РН strain against spring wheat head blight

The effect of the preparation on bases of Bacillus subtilis 11РН strain with high antagonistic activity against Fusarium fungi has been researched in field conditions. It has been shown that endophytic antagonist B. subtilis 11РН is more effective in decreasing grain head blight prevalence than well-known systemic fungicides. It has been established that efficacy of Fusarium infection protection of spring wheat ear increases when seeds and ears are treated in an aggregate. It has been revealed while treating grain with fungicides and biopreparations that there is a tendency to predominance of the species the most representative in the searching natural agricultural zone.
