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.

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 […]

Could a herbicide-resistance gene provide fitness benefits in the absence of the herbicide?

A really interesting study was reported by Nature News, and has been picking up steam around the interwebs (including Wired and Scientific American). The headlines read “Genetically modified crops pass benefits to weeds” and “weeds get unintended ‘fitness’ boost from genetic modification.” The stories are reporting on a study in New Phytologist titled “A novel EPSP […]

Where are the super weeds?

In a recent issue of Nature, Natasha Gilbert took “A hard look at GM crops.” Ms. Gilbert states: “it can be hard to see where scientific evidence ends and dogma and speculation begin.”   “Researchers, farmers, activists and GM seed companies all stridently promote their views, but the scientific data are often inconclusive or contradictory. Complicated […]
