URBANA, Ill. -- Responding to the first known report of waterhemp showing resistance to 4-hydroxyphenylpyruvate dioxygenase-inhibiting herbicides (HPPD) such as Callisto, Impact, and Laudis, weed ...

Herbicide-resistant weeds are a significant threat to soybean, cotton and corn yield potential — and the future of crop production. “Because weed resistance is naturally occurring, it’s a myth that we ...

Herbicide resistance threatens global crop productivity by enabling weed populations to survive once-effective chemical controls. Resistance arises through target-site mutations that reduce herbicide ...

URBANA, Ill. – When agricultural weeds evolve resistance to herbicides, they do it in one of two ways. In target-site resistance, a tiny mutation in the plant’s genetic code means the chemical no ...

If a weed-free field seems like your ultimate harvesting dream, then herbicide-resistant weeds have to be your worst nightmare. For years, new cases of resistance have emerged across the Midwest, with ...

In a paper published Sept. 8 in the journal Communications Biology, scientists from Washington University in St. Louis and the University of Arkansas report that a crop pest called weedy rice has ...

Two Weed Science Society of America (WSSA) member scientists have helped create a digital tool to enable farmers to quickly ...

(Beyond Pesticides, September 28, 2022) ‘Weedy rice,’ a close relative of cultivated rice that invades rice fields and reduces yields, is rapidly developing herbicide resistance in critical rice ...

New research pinpoints genomic regions associated with metabolic or non-target-site herbicide resistance in waterhemp, a problematic agricultural weed. Non-target-site resistance has long been ...

Weedy rice is a closely related cousin of crop rice. It aggressively competes with cultivated rice in the field, leading to loss of yield and reductions in harvest quality that compromise market value ...
