As consumers shift to non-GMO sugar, farmers may be forced to abandon environmental and social gains

Dan Charles at NPR has recently done two interesting pieces about sugar production. In the first, he uses sugar as a proxy to look at the environmental costs and trade-offs of growing food in different places. It makes for an interesting comparison because there are two completely different crops (sugarcane and sugarbeet) that can be grown […]

Dead plants are probably bad for earthworms

I’ve gotten a number of questions recently about a new study titled “Glyphosate-based herbicides reduce the activity and reproduction of earthworms and lead to increased soil nutrient concentrations” that was recently published in the online journal Scientific Reports. Although the title seems pretty straightforward, there are some flaws in the study design that preclude any broad conclusions from this research. […]

Trends in corn herbicide use (1990 to 2014)

USDA-NASS recently published the most recent corn herbicide use data (from 2014). I’ve been looking through the data, because, well, free data! Perhaps the figure below isn’t the ideal way to present it, but there are some interesting trends that can be observed this way. Total herbicide use in corn (in weight of herbicide applied) has remained […]

Glyphosate and Cancer: What does the data say?

A little over a week ago, the International Agency for Research on Cancer (IARC) announced that glyphosate would be added to their list of agents that are “probably carcinogenic to humans.” Glyphosate wasn’t the only pesticide added to the list, but as Nathanael Johnson noted at Grist, glyphosate tends to be something of a lightning […]

Glyphosate use in wheat

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. […]

Seralini Rat Study Revisited

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 […]

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 […]
