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.

Who funds my weed science program?

This is the second post in a series about transparency and funding sources for my weed science research program. An introduction can be found here: On transparency, intimidation, and being called a shill. Since 2012, around two-thirds of my research funding has come from competitive grants. By competitive grants, I mean projects that I’ve developed […]

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 […]

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

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 […]

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.
