Diseases Last week, the scouts continued to find a few fields with tanspot at low incidence and severity. Weather fronts continue to bring scattered showers across much of Minnesota. Only the northern halves of Kittson and Roseau counties continue to miss these showers and thunderstorms, and wheat fields in that area are showing signs of moisture stress. Consequently, the conditions for developing small grain diseases, including FHB, are much more favorable for most. However, as a consequence of the hit-and-miss nature of these rain events, both the NDAWN disease forecasting and the national risk model might be overestimating the risk for some of your fields if last week's rains kept missing your fields and fields are much drier (and therefor less likely to accumalate the needed leaf wetness duration periods) than estimated by the tools when the tools extrapolate the data from the data collection points to your fields in the coming days. For oats and barley that...
