Small Grain Disease Forecasting Model



July 15, 2014

According to the IPM survey scouts, tan spot, septoria, and bacterial leaf streak are the most common foliar diseases detected on the upper portion of the wheat plant. Scab is starting to be reported in winter wheat and early seeded spring wheat. The fields where scab was detected were flowering during the later part of June when most of the state was under a high risk of scab development. More IPM survey information can be found at IPM Survey

For the past four days, the cool, windy and dry weather has reduced the risk of scab for most of the state. Central and northeast ND are the areas with greatest risk of scab development if very susceptible and susceptible varieties were used. For late planted spring wheat, continue to monitor environmental conditions as the crop approaches flowering and use the NDSU Small Grain Disease Model and FHB Alert Center in respective areas.

If you have any questions, contact the Department of Plant Pathology, NDSU, Fargo, ND 58105 (701-231-7627).
