Latest 2,4-Dichlorophenoxyacetic acid Stories

WSSA has published a new article. As the cost and scale of farming operations have increased, so has the usage of herbicide-resistant crops. Lawrence, Kansas (PRWEB) March 22, 2013 As the cost and scale of farming operations have increased, so has the usage of herbicide-resistant crops. These crops provide a weed management tool to meet the needs of modern agriculture. A corresponding decrease has been noted in the use of soil-applied herbicides that farmers have relied on heavily in...

WASHINGTON, Nov. 28, 2012 /PRNewswire/ -- Citing the human and environmental health risks of 2,4-D, an ingredient in the notorious Vietnam era defoliant "Agent Orange," the national Just Label It (JLI) coalition called on Agriculture Secretary Thomas Vilsack to deny approval of genetically engineered (GE) 2,4-D resistant corn. "Corn may be as American as apple pie, but if it's genetically engineered it may jeopardize both human and environmental health. It needs to be labeled," said...

The emergence of weeds resistant to the most widely used herbicide is fostering a new arms race in the war against these menaces, which cost society billions of dollars annually in control measures and lost agricultural production. That's the topic of a story in the current edition of Chemical & Engineering News (C&EN), the weekly magazine of the American Chemical Society (ACS), the world's largest scientific society. In the story, Melody M. Bomgardner, C&EN senior business...

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, who say the solution lies in an integrated weed management program. "I'm deeply concerned when I see figures that herbicide use could double in the next decade," said David Mortensen, professor of weed ecology, Penn State. Since the mid-1990s, agricultural seed companies developed and...

2,4-D is coming back. What many might consider a "dinosaur" may be the best solution for growers fighting weed resistance today, said Dean Riechers, University of Illinois associate professor of weed physiology. "Farmers can't imagine going back to 2,4-D or other auxin herbicides," Riechers said. "But herbicide resistance is bad enough that companies are willing to bring it back. That illustrates how severe this problem is." In a recently published article in Weed Science, Riechers and...

FAIRMONT, W.Va., Aug. 22, 2011 /PRNewswire/ -- Mon Power, a FirstEnergy Corp. (NYSE: FE) subsidiary, will use the aerial application of herbicides to help maintain the rights-of-way under some of its West Virginia power lines. The maintenance program is designed to enhance the safety and reliability of its electric service by controlling vegetation that has the potential to interfere with power lines. The company will be applying the herbicides in Clay, Braxton, Nicholas and Webster...

A Purdue University scientist and researchers in Japan have produced a new class of improved plant growth regulators that are expected to be less toxic to humans.Angus Murphy, a professor of horticulture, said the growth inhibitors block the transport of auxin, a plant hormone that, when transported throughout the plant, controls growth processes. Current growth regulators that inhibit auxin transport are inefficient because they also have hormonelike activity or affect other important plant...

They pop up in farm fields across 22 states, and they've been called the single largest threat to production agriculture that farmers have ever seen. They are "superweeds" "“ undesirable plants that can tolerate multiple herbicides, including the popular gylphosate, also known as RoundUp "“ and they cost time and money because the only real solution is for farmers to plow them out of the field before they suffocate corn, soybeans or cotton. Now, thanks to the work of researchers at Dow...

Discovery may provide solution to spread of herbicide-resistant weedsIn an article in the Nov. 23 issue of the journal The Proceedings of the National Academy of Science, researchers with Dow AgroSciences and the University of Missouri report on two bacterial enzymes that, when transformed into corn and soybeans, provide robust resistance to the herbicide 2,4-D. The discovery may soon provide Missouri corn and soybean growers a solution to the growing problem of herbicide-resistant weeds.The...

Using herbicides to sterilize rather than to kill weedy grasses might be a more economical and environmentally sound weed control strategy, according to a study by Agricultural Research Service (ARS) scientists and a cooperator.Rangeland ecologist Matt Rinella at the ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont., conducted the study with colleagues at Miles City and Robert Masters with Dow AgroSciences LLC, in Indianapolis, Ind.Exotic annual grasses such as...
