Effect of pre-crop on severity of Fusarium head blight (FHB) and content of mycotoxins in grain of spring wheat was studied. Pre-crops were grain maize and winter rapeseed. In years, when conditions were favorable for FHB development, an increased severity of wheat head infections was observed on stands sown after grain maize. Wheat grain samples from these stands contained more Fusarium DNA and Fusarium mycotoxins comparing with grain from stands sown after rapeseed. Dominant species causing FHB was F. graminearum. Disease development on wheat heads and mycotoxin concentration in grain strongly depended on weather conditions. Rainfall and relative humidity during heading and anthesis had the strongest effect on results obtained during three years of study.
