Fusarium Head Blight Risk Maps - Archives

The Fusarium Head Blight Risk maps are posted daily, from the beginning of winter wheat flowering until the end of the flowering period for spring wheat. The maps from 2022 show the risk for the development of Fusarium head blight for the date indicated based on the previous seven days of temperature and precipitation. The maps from 2023 show the risk for the development of Fusarium head blight for the date indicated based on the previous 14 days of temperature and relative humidity. Warm, humid conditions occurring when the crop is susceptible to infection (during flowering) favour the development of this disease.
