Central Illinois Corn and Soybean Updates

Published on Friday, September 23, 2016

The 2016 crop continues to mature, though it may not be quite as fast or large as many predicted just a few weeks earlier.

Corn: Recent inspections have indicated a likelihood of large variations. While high yields are expected in the majority of fields, incomplete pollination and aborted kernels (“tipping back”) have been discovered. Corn plants in the V7 to V8 growth stages that encounter large temperature variations can suffer later with pollination. Corn planted the last week of April into the first week of May appears to have a higher frequency of pollination symptoms. Kernel tip-back could be related to the numerous cloudy days during the first three weeks of August. Test weight may also be lower due to reduced photosynthesis during grain fill. Neither issue will reduce yield significantly. While rootworm beetle numbers remained low, Japanese beetles have made a return in many parts of central and western Illinois.

Soybeans: Resistance of pigweed species to glyphosate and PPO herbicides has farmers looking for alternative herbicide programs to gain control in their fields. Once again, Beck’s will be the leader among seed suppliers to provide farmers with new herbicide traits as they receive full approvals.
