Management interference flagged in Environmental Protection Agency’s dicamba decision

Office of inspector general says decision ran counter to EPA’s Scientific Integrity Policy

Three senior United States Environmental Protection Agency (EPA) managers altered scientific documents to support the EPA’s decision to extend the registration of the herbicide dicamba in 2018, contrary to EPA’s Scientific Integrity Policy. That’s the conclusion of the EPA’s office of inspector general (OIG) in its report released May 24. The EPA’s decision to extend

The Keep It Clean campaign uses a ‘traffic’ system to quantify trade risk from crop protection products.

Industry program helps avoid residue problems on exported crops

Canadian farmers are being encouraged to use an industry alert program to keep unacceptable pesticide residues on crops from spiralling into potential trade problems. The voluntary program called Keep It Clean informs producers about which products to use on cereal, oilseed and pulse crops and which ones to avoid so as not to exceed maximum


Herbicide resistance is a growing concern due to glyphosate-resistant kochia (seen here) and the yet small but aggressively spreading waterhemp.

Former weed specialist back on the job

Battling weed resistance will be hard work, says Kim Brown-Livingston

Kim Brown-Livingston says she’s optimistic as she takes the role of provincial weed specialist. “We have a great future,” she said. “We’re going to continue on, and our farmers are doing a really good job of it now.” Brown-Livingston previously held the role of weed specialist from 1998 to 2013 before moving on to work

German cabinet approves legislation to ban glyphosate from 2024

Law would still need parliamentary approval

Berlin | Reuters — Farmers in Germany will have to gradually reduce their use of glyphosate and stop using it completely from 2024 in order to preserve clean habitats for insects, under draft legislation passed by the country’s cabinet on Wednesday. “The exit from glyphosate is coming. Conservationists have been working toward this for a

Comment: Glyphosate and livestock. It’s all in the dose

Studies have found no effect on digestive bacteria or nutrient uptake

As an animal nutritionist, I’m concerned about the health and welfare of farm animals. Animals that are stressed due to inadequate housing conditions or nutrition are less sustainable. That’s why I read the article “Herbicides and Horses” with great interest. In the article, the author speculates that glyphosate’s chelation and antimicrobial properties can have negative

Variables like weed species and recent and expected frosts will weigh into management decisions

Add the weather forecast into your calculations when planning fall weed control. It’s prime weed control season for perennial weeds like Canada thistle and winter annuals and acting now can help you, come spring. “A lot of the winter annuals are starting to become problems because if we don’t do any kind of control in

Horse Health: A ubiquitous herbicide is beginning to come under increased scrutiny by scientists

The implications for the widespread use of glyphosate-based herbicides in our environment has been increasingly mired in controversy despite regulatory assurances of safety. After close to three decades of use there is a growing body of scientific evidence emerging which presents unintended biological consequences of this chemical and its formulation. Research is postulating adverse mechanisms



Herbicide-resistant wild oats are still controlled by glyphosate — for now.

Now’s the time to find resistant weeds

Herbicide-resistant weeds are on the rise and pre-harvest is a good time to find them

Delaying the onset of herbicide-resistant weeds isn’t a lost cause. In fact the more vigilant a farmer is the more success they’ll have, says Ingrid Kristjanson, a farm production extension specialist with Manitoba Agriculture and Resource Development (MARD). With farmers checking crop maturity as harvest grows near, it is also a good time to scout

Dicamba-resistant Palmer amaranth is showing up in Tennessee. Farmers there are already in a battle with glyphosate-resistant Palmer amaranth.

Dicamba-resistant Palmer amaranth found in U.S.

Farmers there started growing dicamba-tolerant soybeans in 2016

The list of herbicide-resistant weeds continues to grow. Dicamba-resistant Palmer amaranth weeds have been found in parts of Tennessee, University of Tennessee Extension weed specialist Larry Steckel wrote in a July blog. “Results from some of the greenhouse experiments this winter and spring, as well as in-field research this growing season, would suggest that our
