Control of malting barley Fusarium head blight by bioagents

The routine and prophylactic use of fungicides in cereals leads to increased aggressiveness Fusarium infections. Cross-resistance triazole compounds represents a significant health risk both plants humans. application some widely used causes production DON. Residual concentrations hydrophobic triazoles change chemical profile malt cause delayed fermentation with an impact on alcohol content. Increasing legislative restrictions pesticide applications encourage the search for alternatives, starting overview current state knowledge biological protection against spp. Despite fact that bioagents have been researched intensively, including field several registrations, preparations disease control head blight (FHB) malting barley are not mass scale. Generally, appear be quite sensitive environmental changes soil variability, which problems evaluation their effectiveness under conditions. For efficient barley, based biopreparations registered FHB combined weather prediction system can recommended. With emphasis occurrence graminearum as key producer deoxynivalenol (DON), should employed from plant emerging milk stage. When predicting high incidence pathogen, intervention must considered. However, repeated conditions together implementation directly into process proved promising way decrease interventions cultivation barley.
