Pre-emergence herbicides with residual activity are an important component of high-yielding cropping systems. Residual herbicides applied prior to wheat emergence can be part of a good weed management system in wheat production.
Cover crop response to herbicides will be influenced by a number of factors, including biological and biochemical characteristics of the plant, chemical characteristics of the herbicide, and weather conditions since herbicide application.
With row crop harvest well underway, it is time to start planning fall herbicide applications. Herbicide applications in late October through November can improve control of difficult winter annual weeds.
