The cost of preventing herbicide resistance


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!


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


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 […]

What does Chipotle’s switch to non-GMO ingredients mean for pesticide use?


A couple weeks ago, Chipotle announced they were removing genetically engineered crops (called GMOs) from their menu. Kind of. As you might expect, the announcement was covered widely in the media. Interestingly, though, most of the coverage wasn’t very positive. There’s a fairly long list of responses to the Chipotle decision if you’d like to read […]

Stop saying organic food is less safe, unless you can provide evidence


A recent article from Western Producer titled “Canada has a world-class food system” was recently re-posted by the Genetic Literacy Project (GLP). GLP, whose stated mission is to “explore the intersection of DNA research, media and policy to disentangle science from ideology”, commonly aggregates news stories. But when they re-posted this particular article, the headline was changed pretty […]

A 40 year veteran of weed research reflects on his career


Bob Wilson, the weed specialist at the University of Nebraska’s Panhandle Research & Extension Center is retiring this month. Dr. Wilson has been a long-time mentor to me, serving as advisor for my M.S. and co-advisor for my PhD. Since then, we’ve collaborated on many projects aimed at helping sugarbeet producers better manage difficult weeds. […]

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. […]
