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 […]
The monarch butterfly is in bad shape. The number of monarchs returning to their overwintering sites in Mexico has been declining steadily for at least a decade. The consensus suggests there are several reasons for this decline, including loss of their overwintering habitat and unfavorable weather patterns. But the purported cause of monarch decline that […]
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 […]
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 […]
As I was updating information on herbicide resistant weeds for class this week, I wanted to find some hard numbers on the large-scale impact herbicide-resistance can have. Obviously, my first thought was to find information on cotton production in the South. Glyphosate-resistant Palmer amaranth has been something of a poster child for the potentially devastating […]
I made this word cloud in preparation for the class I’m teaching tomorrow. I thought it was pretty interesting, so I decided to post it here and share. In class, we’re going to discuss the effectiveness of various practices to manage herbicide resistant weeds. In preparation for tomorrow’s discussion, I asked my students to review […]
A really interesting study was reported by Nature News, and has been picking up steam around the interwebs (including Wired and Scientific American). The headlines read “Genetically modified crops pass benefits to weeds” and “weeds get unintended ‘fitness’ boost from genetic modification.” The stories are reporting on a study in New Phytologist titled “A novel EPSP […]
I’ve been meaning to write a post on monoculture for quite some time. In fact, I began writing this post over 8 months ago, but for various reasons this topic never made the top of my priority list. This tweet by Michael Pollan finally prompted me to revisit this topic: Grist take on the Harmon […]
Quite sad. Reminds me of the 3 steps for becoming an anti-GMO activist I wrote about last summer: 3 simple steps for anti-GMO activists: Oppose GMO crops on the basis that there is insufficient research. Destroy the research. Go to 1. Read more about destruction of the Golden Rice study at Biofortified.org
Weeds have been in the media quite a lot lately. Usually related to some sensational story about “superweeds” and how they’re “winning.” So it was extremely refreshing to read the measured take by Carl Zimmer in the New York Times Environment section, titled “Looking for Ways to Beat the Weeds.” Zimmer doesn’t resort to over-the-top […]
