The Sclerotinia Risk Map is now Interactive

The Sclerotinia risk map is now interactive! The maps are available through the NDSU Canola Pathology website. The maps, which are refreshed on a daily basis, can be observed by clicking on the “Risk Map” button. While the map still represents areas with low, intermediate and high risk in green, yellow and red, respectively; clicking on any NDAWN station in the map will now show the estimated percentage of risk of disease development for that station. This information will help growers make a more informed spraying decision. The figure below illustrates the risk for June 22, 2016 with the traditional color codes and showing the estimated risk for Langdon (Figure 1).

Growers should remember two important things when they look at the risk map.  First, the risk only applies to canola once when it is flowering.  Second, the risk map is only as accurate as the weather information we have. Rainfall can be sporadic; if your fields have had more/less rain than the general area, then you may have a relative higher/lower risk.
