Soybeans with resistance to synthetic auxin herbicides, such as 2,4-D and dicamba, are currently in development and may be considered for commercial release in some areas in the near future. While these traits may improve the weed control spectrum and options in soybean, concern has been expressed by specialty crop producers that expanded use of synthetic auxin herbicides may increase risk of off-target herbicide movement. The intent of this paper is to review specialty crop production, with a focus on Wisconsin, and to pose potential components of an “ideal” herbicide stewardship program for discussion.
