Glyphosate use in wheat

ControlFreaksLandscapeWheat.jpg

A blog post titled “The Real Reason Wheat is Toxic” has been making the rounds on social media. The post by the “healthy home economist” is riddled with errors and misinformation.The post contends that glyphosate is commonly sprayed on wheat at harvest time, and that glyphosate then causes health problems when the wheat is consumed.

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 […]

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 […]

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 […]

The “failure” of biotechnology to increase crop yield

SugarbeetInjury

For some reason, over the last few days I’ve heard a lot of people criticizing GMOs for not increasing crop yields. This criticism certainly isn’t new. I don’t really understand the reason for the sudden resurgence of this claim, but it does provide an excuse to address the topic with some actual data. GMOs can claim […]

Does the debate about genetically modified food matter?

Sugarbeet field

Over at Grist, Nathanael Johnson has been writing an excellent series of pieces on genetically engineered crops, called “Panic-free GMOs.” The series as a whole has been excellent, and that is not just my opinion. Keith Kloor, another journalist who has often waded in to the GMO debate, said of Johnson’s Grist series: The overwhelming consensus […]

Draft Environmental Impact Statement for 2,4-D Resistant Corn and Soybean Released

Corn

USDA-APHIS has just released the Draft Environmental Impact Statement (EIS) for 2,4-D resistant corn and soybean. The 2,4-D resistant crops were developed by Dow AgroSciences using genetic engineering. The corn and soybeans will be marketed to growers as the “Enlist” weed control system. Crops with the Enlist trait will not only be 2,4-D resistant, but […]
