Superweeds: A Mutating Problem

Cry_of_Silence (The Outer Limits)

Superweeds have been in been in the news a lot over the last few months. Most of the recent coverage has been related to new 2,4-D resistant crops that were recently approved by the USDA and the new herbicide formulation (2,4-D plus glyphosate) that the EPA is reviewing. Marc Brazeau recently wrote a compelling piece arguing […]

Dear Dr. Oz: We Don’t Spray Feathers

Dr. Oz blowing feathers all over the stage.

Not long ago, in front of a Senate panel, Dr. Oz (the most trusted doctor in America) was told by Senator Claire McCaskill “I don’t get why you need to say this stuff because you know its not true.” Senator McCaskill was referring to the many “miracle” weight loss supplements that Dr. Oz promotes on […]

Is Your Child in a Toxic Spray Zone?

Sprayer

The Environmental Working Group (EWG) recently released a blog post titled “Thousands Of Schools Would be Close To Toxic Spray Zones.” The report basically states that if Enlist Duo herbicide is approved by the EPA, many school-aged children will be put at great risk. Enlist Duo is a new formulation of two well-characterized herbicides (2,4-D […]

Seralini Rat Study Revisited

220px-Rat_siamese

Anyone interested in the GMO debate has probably heard about the Seralini paper that I criticized a while back. That paper was eventually retracted by the original journal, and it has now been re-published in a different journal. There are quite a few articles describing the background, so I won’t get into those details. I suggest reading recent […]

Regulating Herbicide Resistance

2,4-D

A few months ago, I wrote about 2,4-D resistant corn and soybean. At that time, the USDA had just completed it’s draft environmental impact statement for the two crops. While the USDA regulates crops developed through biotechnology, it is the EPA that regulates pesticide use. So before the new formulation of 2,4-D can be applied […]

Salt, Vinegar, and Glyphosate

I’ve been asked quite a few times over the last several years about a “homemade” herbicide recipe that is floating around the web. Many of you have probably seen it posted to Facebook or Twitter or Pinterest, or on your favorite home gardening site. One of my favorite descriptions calls it a “magical, natural, weed killing […]

Defining Agroecology

SmallCroppedWheatLandscape

Agroecology (ag´ rō i kol´ ə jē), n. An ecosystems approach to agriculture. Agroecology. It’s an unfamiliar term to many people. And even people who are actively engaged in some aspect of agroecology sometimes disagree about what it means. I have to admit, even though the term is pretty important to me, I was fairly […]

Fitness of herbicide resistance genes revisited

Figure 2 from Giacomini et al. (2014)

Last August, an article was published in New Phytologist that claimed a transgene added to rice could increase the fitness of a weedy relative. The paper was covered in the media pretty widely. When I read the paper, I didn’t think the authors presented nearly enough data to support their conclusions. You can find my […]
