This website will be updated daily Monday to Friday with the current risk maps.
Please refer to the risk maps to help decide risk to your crop, based on heading and flowering stage of your crops.  Remember the disease triangle – the existence of a disease requires three factors: the interaction of a susceptible host, a virulent pathogen, and an environment favorable for disease development. Therefore, although a risk map may show High to Extreme risk levels due to environment, disease risk may be low if the wheat crop is not at the proper stage for infection.
Depending on the weather, wheat can move through the following stages of development below in as little as five days to more than a week.  So if a fungicide for FHB suppression is planned, scout your fields daily to ensure proper timing.
