Although there have not been widespread reports of stripe rust on wheat immediately to our south, the weather pattern last week raised my level of suspicion a little. The low pressure system sitting still and churning southerly winds all the way from Texas and Oklahoma up to us, then dropping rain, could very well have picked up stripe rust and moved it north, skipping most of Nebraska. Unlike other rusts, the cool weather is ideal for stripe rust development. I expect to see visible rust around 10-14 days after a weather event, so today through next week are prime times to begin seeing the rust. Fungicide applications along with the herbicide on wheat are a good management strategy a vast majority of the time. Winter wheat can be affected at all leaf stages, so look at the upcoming flag leaf minus one and flag leaves to keep them clean, as we know these leaves produce a majority of what gets into the head.
