U.S. EPA reaffirms glyphosate does not cause cancer

Chicago | Reuters — The U.S. Environmental Protection Agency said on Thursday it finished a regulatory review that found glyphosate, the most widely used herbicide in the United States, is not a carcinogen. The conclusion reaffirms the agency’s stance on glyphosate, the key ingredient in Bayer’s Roundup, despite judgments by U.S. juries that have found

Roundup cancer trial postponed to continue settlement talks

Reuters — Bayer AG said on Friday it has reached an agreement with plaintiffs’ lawyers to postpone a Missouri jury trial over allegations its herbicide Roundup causes cancer, to provide room for negotiations to settle the litigation. “While Bayer is constructively engaged in the mediation process, there is no comprehensive agreement at this time.

Fall is the time when you can see what’s survived your crop season’s control efforts.

Fall management key to weed resistance

It’s in the fall you see what worked and what you can change up for next year

When it comes to weed control, fall is often one of your best windows to find out how it’s going and what issues are on the horizon. Tammy Jones, Manitoba Agriculture weed specialist, says the fall season offers a planning window for next year and lets farmers evaluate what went right or wrong this season.

Manitoba Agriculture has recently confirmed more cases of Tall waterhemp in the province. It’s a tier-one noxious weed that must be destroyed no matter where it’s found.

New cases of Tall waterhemp found in Manitoba

This is a Tier 1 noxious weed that Manitoba Agriculture wants to prevent from spreading

Tall Waterhemp has been confirmed in four new Manitoba fields and there are rumours of more, Manitoba Agriculture weed specialist Tammy Jones said in an interview Aug. 2. Tall Waterhemp is a Tier one noxious weed that must be destroyed no matter where it’s found, but that can include hand weeding within crops where practical,

Farmers who maybe weren't too initially concerned about weed pressure will need to keep a close eye on fields.

The researchers started with a single seed of Amaranthus hypochondriacus, their test plant, and grew generations of the plant to produce the seeds they needed for their experiments.

New mutations for herbicide resistance rare

Most resistance seems to come from pre-existing genetic conditions

After exposing more than 70 million seeds to a soil-based herbicide, researchers at the University of Illinois were not able to find a single herbicide-resistant mutant. Though preliminary, the findings suggest that the mutation rate in amaranth is very low, and that low-level herbicide application contributes little — if anything — to the onset of

Second U.S. jury finds Bayer’s Roundup caused cancer

Reuters — A U.S. jury on Tuesday found Bayer’s glyphosate-based Roundup herbicide caused cancer, a blow to the company eight months after another jury issued a US$289 million verdict over similar claims in a different case. Tuesday’s unanimous jury decision in San Francisco federal court, which came after five days of deliberation, was not a

Colombian president defends use of glyphosate on coca crops

Bogota | Reuters — A judicial ban on aerial spraying of glyphosate herbicide to eliminate coca crops should be modified, Colombia’s President Ivan Duque said on Thursday, because expansion of the crop since the ban threatens peace efforts. The Andean country suspended aerial fumigation of coca, the raw ingredient in cocaine, with the Monsanto herbicide


Assure herbicide’s active ingredient under new ownership

Now being put to work in Enlist corn, the active ingredient in Assure II herbicide has a new owner. California-based American Vanguard Corp., the owner of ag chemical producer Amvac Chemical, announced Thursday it has bought the quizalofop-p-ethyl (QPE) product line of herbicides from DowDuPont’s ag division, Corteva Agriscience, for an undisclosed sum. A Group

Even less competitive crops can benefit from an integrated weed management strategy.

Crop establishment important for weed management

Combining many tools into an overall integrated weed management strategy is a winner

There are many components to integrated weed management (IWM) including crop rotation, seeding rates, chemical, cultural and mechanical controls, but one of the most vital aspects of any successful IWM is crop establishment, says Dr. Rob Gulden of the University of Manitoba. At this year’s Crops-A-Palooza event in Portage la Prairie, researchers including Gulden manned
