The evolution of multiple herbicide resistance in annual weeds has forced the development of innovative and alternative, non-chemical weed control strategies.
A greenhouse experiment found glyphosate resistance will probably persist, making it unlikely that susceptible Palmer amaranth would once again become dominant if glyphosate use was discontinued.
Plant Science Consulting director and weed science team researcher, Dr. Peter Boutsalis, Adelaide University, discusses some of the finer points of herbicide-resistance testing.
Palmer amaranth (Amaranthus palmeri) has garnered much attention recently in both academic discussions and popular press releases, and with good reason. Among the weedy species of Amaranthus, Palmer amaranth has the fastest growth rate and is the most competitive with the crops common to Midwest agronomic cropping systems. Soybean yield losses approaching 80% and corn
Mississippi State University scientists are fighting glyphosate-resistant Italian ryegrass with a research-based plan of attack.
FMC Agricultural Solutions has announced a new EPA crop registration of its Anthem SE herbicide now for use on soybeans.
The highly anticipated Enlist 2,4-D herbicide-tolerant corn has been issued a U.S. patent; Dow AgroSciences expects to launch the product in 2015.
Callisto GT post-emergence herbicide has received registration from EPA and all major corn-producing states.
Dow AgroSciences recently won two Agrow Awards recognizing industry-leading technology and innovation within the agriculture research industry.
Although there are currently dozens of weeds that show some kind of resistance to herbicides, these five are the most troublesome.
