Remember the disease triangle when using FHB risk maps

June 29, 2015 - Manitoba Agriculture, Food and Rural Development is providing daily maps on the risk of Fusarium Head Blight (FHB) infection. The maps are available daily on MAFRD's website.

Changes over the past week are a clear signal to producers to continually scout their fields for local conditions as their crop progresses. Pam de Rocquigny, MAFRD cereal crops specialist, says to remember the disease triangle – the existence of a disease requires three factors: the interaction of a susceptible host, a virulent pathogen, and an environment favourable for disease development.

Therefore, although the most current risk map shows high risk levels due to environment in some areas of the province, disease is prevented if the winter/spring wheat is not at the proper stage for infection.
