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

GH Student Projects 052-1

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 […]

The role of reflected light quality in crop-weed interactions

WeedReflectedSpectra

Much of my time on social media and on this blog is devoted to pesticide and GMO issues. These topics tend to be relatively controversial, and often misunderstood. So I suppose addressing these issues is a reasonable use of my outreach time. But these issues are actually only one component of our weed science research […]

Enlist Duo registration being withdrawn by EPA due to “synergistic effects”

Sunflower sprayed with 2,4-D

Chris Clayton at DTN is reporting this morning that EPA is withdrawing registration of Enlist Duo herbicide. The decision was posted yesterday in court documents. From the DTN report: “The filing was posted in a Ninth Circuit Court of Appeals case filed by the Natural Resources Defense Council and the Center for Food Safety against […]

The cost of preventing herbicide resistance

Kochia-ak2015

In my last post, I reviewed some recent research that suggests one of the best ways to delay the evolution of herbicide resistant weeds is to use mixtures of effective herbicides. Resistance is initially a very rare trait within a weed species, so the probability that any particular individual plant will be resistant to two […]

Want to reduce herbicide resistance? Spray more herbicides!

GRkochia

A while ago, I wrote a post summarizing the pros and cons of using a regulatory framework to slow the evolution of herbicide resistant weeds. As a part of that post, I suggested there exists a “resistance management paradox.” In a nutshell, to reduce the problem of herbicide resistant weeds, one important strategy may be to actually use more herbicide. […]

GMOs, Herbicides, and the New England Journal of Medicine

Sprayer

An opinion piece was recently published in the New England Journal of Medicine, written by Dr. Philip Landrigan (an M.D.) and Dr. Charles Benbrook (PhD) titled “GMOs, Herbicides, and Public Health”. I was asked to review the piece this week, and I can only assume it will eventually make the rounds on social media. So I thought […]
