If you missed the March 14 Nebraska Extension webinar on "Insects in Cover Crop Systems," it's now available here or on YouTube at https://www.youtube.com/watch?v=XGjuzMlrjhQ. It includes an update on beneficial insects, pest challenges, and what researchers learned about wheat stem maggots moving from wheat and cereal rye into corn in 2017.
A related CropWatch article, Wheat Stem Maggot in Corn: Plan on Scouting Your Cover Crop Fields this Spring, has additional information.
The webinar features Justin McMechan, extension crop protection and cropping systems specialist, presenting on findings from 2017. Co-authors were Robert Wright, extension entomologist, and Gabi Carmona, entomology masters student.
