Abstract
Postemergence herbicides are the most widely used weed management tool in Iowa's corn and soybean acres. Application of the herbicide directly to the target bypasses the myriad of soil interactions that influence preemergence herbicides. However, killing weeds with postemergence products is not as simple as merely getting the herbicide onto the leaf of the weed. This paper will discuss the factors that influence the activity of postemergence weeds.
