Leaf rust, stem rust, and scab are all being reported this season. NDSU Extension Cereals Plant Pathologist Andrew Friskop says the different planting dates are impacting the risk of Fusarium head blight. “Our greatest scab risk window started around the 4th of July and extended on for two or three weeks there.” The scab risk is starting to come down. “The only downside is we are having some high-humidity mornings; fog is starting to roll in, too so we could see some scab on the late-planted wheat,” said Friskop. “We might not see a yield loss, but we might see some more vomitoxin. It’s all hypothetical at this point but be aware.”
