Alyssa Essman, assistant professor in the Department of Horticulture and Crop Science at Ohio State University, has been researching integrated weed management strategies and how cover crops can be used to supplement conventional herbicide programs.
BASF is releasing two new InVigor hybrid canola varieties for the 2025 growing season to follow on from its launch last spring of its initial triple-trait variety.
Although glyphosate provided superior weed control in the early years, most of the weeds in the dataset showed signs of adaptation to the chemical in just two to three years.
The study says the data show a rapid falling-off of glyphosate effectiveness against seven major weeds after the first couple of years. The authors conclude that intensive use of any one weedkiller like glyphosate year-after-year serves to speed up evolution in weeds to resist it.
In a world-first breakthrough for research into herbicide resistance, a team of Australian and international scientists has discovered a new glyphosate resistance mechanism in plants that has similarities to cancer drug resistance in humans, say researchers from the University of Western Australia.
A study from the University of Florida indicates that Palmer amaranth can evolve life-history traits to increase its potential to grow and reproduce in various cropping systems.
Ohio State University Extension stresses that growers should have a zero tolerance policy on Palmer amaranth and what they can do to prevent the weed from establishing.
