Understanding how weeds are resistant to herbicides
In a little over seven hours, University of Illinois weed scientist Patrick Tranel got more genetic information about waterhemp than in two years time in a lab. The genetic information was obtained...
View ArticleWorst weed the culprit of herbicide resistance
Scientists at the University of Adelaide's Waite Research Institute have discovered new cases of herbicide resistance in annual ryegrass, the most serious and costly weed of Australian cropping.
View ArticleWaterhemp rears its ugly head ... again
Waterhemp has done it again. University of Illinois researchers just published an article in Pest Management Science confirming that waterhemp is the first weed to evolve resistance to HPPD-inhibiting...

View ArticleLeading crop scientist warns against herbicide overuse
Overuse of the herbicide glyphosate (Roundup) has caused US crops to become infested with glyphosate-resistant weeds - and a world-leading researcher at The University of Western Australia is fighting...
View ArticleResistance evolution in weeds puts 2,4-D under the microscope
(Phys.org)—Researchers are investigating why a broadleaf herbicide used successfully to control weeds in agriculture for the past 60 years is now no longer effective against the crop weed, wild radish,...
View ArticleCarson's Silent Spring turns 50
(Phys.org)—Silent Spring, by marine biologist Rachel Carson, was first published 50 years ago this month, and two Perspective articles in the Ecology section of the journal Science examine the legacy...
View ArticleInvasive weeds could shed light on climate-coping
(Phys.org) —In the race to adapt to climate change, weeds may be the winners. Understanding their well-honed coping mechanisms could inform strategies for ecological management, says a Cornell crop and...
View ArticleOvercoming multiple herbicide resistance
(Phys.org) —British scientists from several research facilities across the country have found that an enzyme called glutathione transferase which is known to neutralize toxins meant to stem the growth...
View ArticleModifying rice crops to resist herbicide prompts weedy neighbors' growth spurt
Rice containing an overactive gene that makes it resistant to a common herbicide can pass that genetic trait to weedy rice, prompting powerful growth even without a weed-killer to trigger the...
View ArticleIntegrated weed management best response to herbicide resistance
Over-reliance on glyphosate-type herbicides for weed control on U.S. farms has created a dramatic increase in the number of genetically-resistant weeds, according to a team of agricultural researchers,...
View ArticleBioluminescent technology for easy tracking of GMO
It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research published in BioMed Central's open access journal...
View ArticleGlyphosate-resistant 'superweeds' may be less susceptible to diseases
(Phys.org) -- Scientists searching for clues to understand how superweeds obtain resistance to the popular herbicide glyphosate may have been missing a critical piece of information, a Purdue...
View Article'Superweeds' linked to rising herbicide use in GM crops
A study published this week by Washington State University research professor Charles Benbrook finds that the use of herbicides in the production of three genetically modified herbicide-tolerant...
View ArticleGreenpeace warns EU off herbicide-tolerant GM crops
Global environmental watchdog Greenpeace launched a new report Monday warning the European Union against authorising herbicide-tolerant genetically engineered (HTGE) crops, saying they would lead to...
View ArticleScientists fight 'super weeds' with sustainability
(Phys.org)—Across the United States, fields of genetically engineered crops have become laboratories for the evolution of glyphosate-resistant (GR) weeds. These fast-growing "super weeds"—resistant to...

Rubber, cotton, rice, palm oil, bananas, other fruits and vegetables - these are just some of the crops under threat from a weed that has recently developed resistance to some of the most powerful...
View ArticleUS 'superweeds' epidemic shines spotlight on GMOs
The United States is facing an epidemic of herbicide-resistant "superweeds" that some activists and researchers are blaming on GMOs, an accusation rejected by industry giants.
View ArticleStudy uses farm data to aid in slowing evolution of herbicide-resistant weeds
The widespread evolution of herbicide-resistant weeds is costing farmers, especially through decreases in productivity and profitability. Although researchers and industry personnel have made...
