Waterhemp is already one of the most problematic weeds in the Midwest and South. But researchers writing in the latest edition of the journal Weed Science say its control challenges are getting even tougher. more »

Scientists have discovered an important new reason to focus on removal of invasive plant species. A recent study featured in the journal Invasive Plant Science and Management shows that removing invaders alongside a stream or river can greatly improve the biodiversity of aquatic organisms. more »

With herbicide resistance on the rise, more farmers are making tillage the foundation of their integrated weed management program. But new research shows that when tillage occurs can make a big difference more »

Palmer amaranth is widely considered to be one of the most damaging and difficult to control agricultural weeds in North America. A lot of time and attention has been devoted to herbicide-resistant Palmer amaranth more »

It is easy to assume that getting rid of invasive plants will allow a local ecosystem to return to its natural state, with native vegetation flourishing once again. But a new study featured more »

Cropping systems based on the auxin-containing herbicides dicamba and 2,4-D offer new control options in the battle against glyphosate-resistant broadleaf weeds. According to research published more »

Land managers are gaining an upper hand against exotic tamarisk in the western U.S. thanks to beetles introduced to control the invasive plant. Unfortunately, though, a secondary challenge remains. more »
