Junglerice has become a significant problem in dicamba-resistant cotton and soybean crops. In Tennessee, for example, it is found in 76 percent of dicamba-resistant cotton fields and 64 percent of dicamba-resistant soybean fields.…
Previous research has shown that tillage-based, organically grown crops benefit from better soil quality than those grown under conventional tillage. They compete more effectively against weeds and produce better yields.…
In this age of globalization, invasive plants can quickly become established in new countries and new continents. To arm stakeholders with the information they need to take action, the journal Invasive Plant Science and Management (IPSM) has launched a new series on the biology and ecology of invasive plants.…
Horseweed is undoubtedly one of the most troublesome weeds in the world. Herbicide-resistant populations are now found in 18 countries, and many are resistant to multiple herbicide sites of action.…
Complaints about off-target movement of dicamba, 2,4-D and other synthetic auxin herbicides persist, despite the introduction of reduced-volatility formulations. One indicator: a survey shows that 30 percent of Nebraska growers believe injury to susceptible soybean crops is caused by off-target movement of dicamba applied to corn.…
Greenskeepers and landscape managers may be losing their battle with annual bluegrass – an unsightly weed that competes with desirable turf and produces an uneven surface for golf and other sports.…
South Texas is a hyperdiverse region with wide variations in landscapes and native species. But that diversity is being threatened by invasive, exotic grasses.…
Cover crops are a proven tool for suppressing many troublesome weeds. But what about the residues they leave behind? Research featured in the journal Weed Science shows the composition of those residues matters – influencing both the control of summer annual weeds and the yields produced by crops.…
Many millions of homeowners use backyard feeders to attract birds, but researchers say there may be one downside to this popular hobby. …
