Palmer amaranth update



On September 24th Dr. Aaron Hager penned a Palmer amaranth distribution update in the Illinois Bulletin. Dr. Hager shared that recent research conducted in Illinois by Dr. Adam Davis, USDA-ARS plant ecologist at the University of Illinois, demonstrated that there are few landscape-level barriers to the establishment of Palmer amaranth populations in Illinois, and that these populations, once established, are competitive with crop species.  In other words, these results indicate that it's not a question of if Palmer amaranth will become established in Illinois, but rather when and where it will become established. The NIARC was one of the host locations for Dr. Davis's research.
