Research confirms first glyphosate resistant wild radish
The world’s first populations of glyphosate resistant wild radish will be announced at Perth’s Agribusiness Crop Updates, but researchers stress further cases can be minimised if farmers adopt diverse control strategies. Australian Herbicide Resistance Initiative (AHRI) research has confirmed glyphosate resistance in three populations of wild radish, all from different locations in ...

NRDC: Urgent Herbicide Review Needed to Stem Monarch Butterfly Decline
Conservation experts in Mexico today announced that a record low number of monarch butterflies returned this year to their wintering grounds in the mountains of Mexico and their annual migration is at “serious risk of disappearing.” Monarchs, which migrate from Mexico across North America and back every year, have been in serious decline since the 1990s. Experts believe that the ...

EPA Seeks Comment on Proposed Decision to Register Enlist Duo Herbicide Containing the Choline Salt of 2,4-D and Glyphosate
The EPA is making available for a 30-day public comment period a proposed regulatory decision to register Enlist Duo containing glyphosate and the choline salt of 2,4-D for use in controlling weeds in corn and soybeans genetically engineered (GE) to tolerate 2,4-D. Weeds are becoming increasingly resistant to glyphosate-based herbicides and are posing a problem for farmers. If finalized, ...

Respect the Rotation: Glyphosate-Resistant Weeds One Year Later
Growers, consultants, weed scientists, researchers and government agency officials who participated in the July 2010 launch of the Respect the Rotation™ initiative have taken measureable steps toward progress in the fight against the proliferation of glyphosate-resistant weeds. But university experts still believe the system will fail if current practices continue. There is enough of an ...

Ohio State Weed Specialist: Preventing the Spread of Costly Herbicide-Resistant Weed Calls for Zero Tolerance
If you see even one of this notoriously damaging weed in your field, pull it up – fast! Otherwise it could be the worst mistake you’ve ever made in your farming career, according to a researcher from Ohio State University’s College of Food, Agricultural, and Environmental Sciences. Palmer amaranth, a glyphosate-resistant weed also known to many cotton and soybean farmers in ...

GM crops could reduce need for herbicides
Analysis of large-scale European field trial data reveals that lower quantities of herbicides are applied to crops genetically modified for herbicide-resistance compared with conventionally grown crops. However, the data also suggest that biodiversity may be reduced if genetically modified (GM) crops are grown widely. Transgenic crops are currently grown in 22 countries across the world, ...

Valor brings flexibility to summer weed control
New pre-emergent residual registrations for Valor herbicide in fallows and prior to planting summer crops greatly broadens crop rotation flexibility and boosts efforts in combating herbicide resistance. New registrations for Valor herbicide now enable it to be used for highly effective pre - emergent (residual) control of a broad range of problem weeds in fallow and prior to planting summer ...

NRDC Petitions EPA to Save the Monarch Butterfly
Skyrocketing use of the weed-killer glyphosate, first marketed as “Roundup,” is devastating monarch butterfly populations, and new safeguards should be put in place immediately to save the iconic species from further decline, the Natural Resources Defense Council said today. In a petition filed with the Environmental Protection Agency, NRDC said current uses of glyphosate are causing ...

USDA approves new modified corn seeds, soybean seeds
The Agriculture Department has approved the use of genetically modified corn seeds and soybean seeds that are resistant to a popular weed killer. However, farmers won't be able to take full advantage of the seeds until the Environmental Protection Agency issues a second ruling allowing the use of Enlist, a new version of the 2,4-D weed killer that's been around since the 1940s. The EPA has said ...

Beast of a weed creeping across Midwest from south
It's a beast of a weed, creeping north into the Midwest from cotton country. Palmer amaranth can shoot up as high as 7 feet, and just one plant can produce up to a million seeds. Herbicide is increasingly futile against it, and the weed's thick stems and deep roots make it hard work to clear by hand. It can slash yields and profits when it gets out of control. Midwestern weed scientists are ...

How to Keep Specialty Crops Safe from Herbicide Drift
Ohio’s corn and soybean growers could soon be spraying a lot more of two powerful herbicides on their fields. That’s why agricultural experts from The Ohio State University are offering tips on how to keep those herbicides from getting onto other crops, especially valuable specialty crops such as grapes. Doug Doohan and Roger Downer, both of Ohio State’s College of Food, ...
