Corn rootworm larvae begins hatching in late May to June. “Generally, corn rootworm hatch occurs close to the time that we begin seeing lightning bugs outside in the evenings,” said AgVenture Agronomy Lead Louis Sutton. “This is not 100% true, but it gives us a good indication of the hatch timing. When this happens, set a reminder to begin scouting in the next couple of weeks.”
Managing corn rootworm beetles can be done several different ways. Crop rotation is one way to interfere with the corn rootworm life cycle by using a corn/soybean rotation.
Looking at and evaluating your current nitrogen and sulfur programs is IMPERATIVE to pushing yields and making improvements in the future. Every year is key to be evaluating nitrogen/sulfur programs with the losses that can happen throughout the year.
The start of corn harvest looks very different for many operations. At Cutting Edge Consulting, we believe that there are significantly higher yields to be had if we start harvesting corn around 25-26% or higher moisture and then dry it down.
