Synthetic Auxin Resistance
Globally, the most important synthetic auxin resistant weeds are Kochia, Wild Radish, Corn Poppy, and Wild Mustard. Synthetic auxin resistance in two other species, Tall Waterhemp and Common Lambsquarters, are not widespread yet, but have the potential to become serious problems in the United States if they are not managed properly.
The Synthetic Auxin Working Group has created a series of fact sheets on these important synthetic auxin resistant weeds. Visit our Fact Sheets page for more information.
