Surveys show horseweed is a persistent and unpredictable foe in soybean crops

Horseweed is one of the most common and most troublesome weeds in soybean production—shown to cause yield losses of up to 39 percent in the Midwest growing region. A single horseweed plant can produce up to 200,000 seeds that can be easily spread across vast distances. In addition, herbicide resistance has made horseweed increasingly difficult to control.
