Search results for “weed resistance”:
In a collaborative research project, a team of scientists have conducted a nationwide assessment of factors contributing to an epidemic of herbicide-resistant weeds in the United Kingdom (UK). Their paper was published in Nature: Evolution and Ecology this week. It paints a crystal-clear picture of rapidly rising weed resistance – and a clear correlation with […]

It was developed for […]
DTN Progressive Farmer reports that dicamba-resistant weeds appear to have started to crop up in the Midwest and Midsouth regions. These soy and cotton growing regions have seen a huge increase in dicamba use over the last couple of years since dicamba-resistant varieties of these crops were introduced. An estimated 60 million acres of dicamba […]

“Weeds are winning the war against herbicide resistance.” This stark analysis is part of the title of a new Scientific American deep-dive into efforts to battle weed resistance. The author, Brooke Borel, summarizes the latest science, including research done at North Carolina State University. Scientists at NC State reached the sobering conclusion that “[there is a] […]

A new study published in the prestigious journal Proceedings of the National Academy of Sciences takes some of the mystery out of how aggressive weeds like Palmer amaranth and common waterhemp developed resistance to glyphosate herbicides so quickly. Researchers from Kansas State University have discovered that these pigweeds develop extra-chromosomal circular DNA (eccDNA), genetic material that […]

Liebman and Gallandt, 1997 Matt Liebman and Eric Gallandt, “Many Little Hammers: Ecological Management of Crop-Weed Interactions,” In Ecology and Agriculture,” Ed: L.E. Jackson, 1997, Academic Press. SUMMARY: This is the first introduction of the phrase “many little hammers” to describe what is now known as integrated weed management, or IWM. IWM relies on using a […]
Herbicide-resistant weeds are a common topic around here, so we were interested in this new science out of Argentina identifying a new “superweed” resistant to glyphosate, dicamba, and 2,4-D. Plus, the researchers learned more about the mechanism of herbicide resistance in one of the most common weed families – the Amaranths (Amaranthus species). Farmers throughout the croplands of the […]

Dr. Larry Steckel, a weed scientist from Tennessee with 30+ years experience working with farmers on pesticide issues, has written a thoughtful piece in the Delta Farm Press about the ongoing dicamba-drift crisis. Steckel is quoted in our Dicamba Watch dynamic presentation and has been an important voice throughout this crisis, now in its third year. […]

Farmers are bracing for a rough season contending with the spread of glyphosate-resistant weeds throughout the Heartland. The collapsing efficacy of genetically engineered (GE), herbicide-resistant (HR) technology coincides with a serious downturn in corn, soybean, and cotton prices. Rising costs for GE-HR seed, the need to markedly intensify herbicide use (driving production costs higher), and […]

Within hours on this Monday, May 13, 2019, the jury in the Pilliod Roundup-non-Hodgkin lymphoma (NHL) trial in Oakland, California is suspected to reach a verdict. It is highly likely the verdict will be the third in a row in favor of plaintiffs, following on the heels of one earlier this spring in the Hardeman […]
