Biologists at the University of York have taken an important step in making it possible to clean millions of hectares of land contaminated by explosives.
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.
(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 University study shows.
Twenty-five years ago, waterhemp was virtually unknown to Illinois farmers. Today, the broadleaf weed blankets corn and soybean fields across the state and the Midwest, causing yield losses from 40 to 70 percent.
Herbicide-resistant weeds are becoming increasingly common in agricultural landscapes. Existing methods for confirming herbicide resistance require knowledge of the genes responsible for target-site resistance, but this information ...
Tossing topsoil around in Australia's often arid farming environment is not best practice, but modelling suggests an occasional turning of the soil can delay the rise of herbicide-resistant weeds.
With herbicide resistance in common weeds already impacting significantly on the WA grain industry's profitability, evidence has now been found of resistance issues in lesser-known and emerging 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 recommendations to slow this ...
