An Evaluation of the Environmental Impact Quotient (EIQ)

journal.pone.0131200.g001

I’ve always been interested in how changes in agricultural production practices impact the environment. In particular, I’ve followed the adoption of genetically modified (GM) crops since I was an undergraduate, and try to stay up to date on research relating to the environmental impact associated with these crops. Several publications over the last decade have […]

Trends in corn herbicide use (1990 to 2014)

CornPoundsStackedLines

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?

CornHerbicides

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

IMG_20140713_165628406

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 and Cancer: What does the data say?

AllCancer_Allcites

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 […]

Toadflax Field Day in Cheyenne

IMG_2327

Do you have a toadflax problem? Have you tried multiple management techniques? Does a yellow-flowered hillside make you shudder? Dalmatian and yellow toadflax (Linaria dalmatica L. and L. vulgaris Mill.) are species on Wyoming’s noxious weed list which can displace desirable forage, reduce species diversity, and spread quickly. These are just a few of the […]

Think you can restore cheatgrass-infested rangeland? Come show us!

Picture 148

Wyoming Restoration Challenge 2015: Cheatgrass Millions of acres of western rangelands are negatively impacted by invasive species, and cheatgrass (Bromus tectorum) is one of the most widespread. Its ability to alter species composition and ecological functions negatively impacts habitat quality for livestock and wildlife alike. Hundreds of research papers have been published on its ecology […]

Top 5 Most Viewed Posts from the Control Freaks – 2014

To celebrate the new year (and because I’d rather spend time with my family than create new content over the break), I’ll be posting the top 5 most viewed blog posts here at the Control Freaks over the next 5 days. But first, I want to thank everyone for reading our little blog. It is […]

A 40 year veteran of weed research reflects on his career

KnissWilson

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. […]

PhD Assistantship in Invasive Weed Ecology and Management Available

TBG Cheatgrass

We are actively seeking an outstanding student for a PhD project investigating the incorporation of threshold concepts and ecological site descriptions for invasive weed management on western rangelands. A successful candidate will be experienced with field study design and subsequent collection and analysis of ecological data in remote sagebrush landscapes. Travel to multiple field sites […]
