Southern rust has now been confirmed in corn in 26 Nebraska counties. As we confirm more Nebraska counties with southern rust, it's important to know that the vast majority of rust reports have been sparse and no fungicide application was required. Continued scouting is urged, as injury can be critical to the grain-fill through dough stages.
Considering the day to day and week to week variability in weather we’ve experienced and the wide range of regional conditions across Nebraska this year, scouting fields for kernel set and overall condition may be more important than ever. Check out these corn reports from across the state.
Will the high temperatures and humidity experienced in the last few weeks impact corn pollination and kernel set? This summary from an earlier CropWatch article, How Extended High Heat Disrupts Corn Pollination, sheds some light on the question.
