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 ...

When weeds begin showing resistance, it’s not a case of the herbicide changing the weed, it’s a simple “survival of the fittest” case, according to a Texas A&M AgriLife Extension Service specialist.

FARGO, N.D. -- A growing problem is creeping up among crops throughout North Dakota and Minnesota. Some weeds have become resistant to the herbicides used to control them. In some parts of the country ...

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 ...

New evidence suggests that herbicide resistance in weeds is more likely to occur from pre-existing genetic variation than from new mutations. After exposing more than 70 million grain amaranth seeds ...

A new map shows which herbicide-resistant weeds have been identified in each county in Eastern Washington and some counties in northeastern Oregon. “We have a resistance problem, and it’s getting ...

Regional wheat, barley and pulse farmers and land-grant universities have teamed up to form a coordinated group of more than 20 scientists devoted to researching herbicide resistance in weeds. The ...

Recently published research in the journal Weed Science shows that waterhemp resistance to protoporphyrinogen oxidase inhibitor (PPO) herbicides can develop from soil-applied preemergence applications ...

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 ...
