The rapid pace of planting in late April followed by rain has resulted in many fields having emerged corn before pre-emergence herbicide and nitrogen applications have been completed. Of particular concern are no-till fields where planting was completed prior to killing emerged weeds....More

"The smaller the weed, the better," says University of Illinois Associate Professor of Weed Science Aaron Hager. Proper timing of the application of postemergence herbicides provides the corn crop with the best opportunity to express its full genetic yield potential. Allowing weeds to compete with the crop for too long reduces its seed yield. Yield losses can accumulate very rapidly, and the associated costs can far exceed the cost of an integrated weed management program that includes a properly timed application of a postemergence herbicide....More

Interest in using multiple modes of herbicide action in weed management programs is increasing, according to Aaron Hager, University of Illinois associate professor of weed science. However, each component of a herbicide premix or tankmix with multiple modes of action is not necessarily effective for every weed or under all application conditions....More

Although the calendar shows it's March, many Midwest farmers are preparing their fields for spring planting like it's the middle of April. That's not necessarily a good thing, says Purdue Extension Weed Specialist Bill Johnson....More
