Abstract
Several herbicides commonly used in Iowa com and soybean production have sufficient persistence for soil residues to remain into the following spring. The shortage of rainfall across much of Iowa during the 2000 growing season may result in higher concentrations of these herbicides in 2001 than normally encountered, thus increasing the possibility of herbicide injury to rotational crops.
