For decades, the fight against weeds in Arkansas agriculture —barnyardgrass and Palmer amaranth, in particular — has been an ongoing war of attrition as weed populations gradually acquire resistance to one herbicidal chemistry after another.
During this time, weed scientists...
The Weed Science Society of America recently released a report based on a recent research workshop on the off-target movement of dicamba herbicides.
