Ok, I'll admit that I fully intended to do something useful today but got distracted thinking about weed control research, weed science extension, and herbicide-resistant weeds (what do YOU think about on Saturday afternoon?).
Anyway, while procrastinating today, I ran across the blog of one of my weed science colleages at the University of Wyoming, Dr. Andrew Kniss. In an October post, Dr. Kniss discussed the question "Do genetically engineered crops really increase herbicide use?" that largely discussed the data in a report on the impact of GMO crops on pesticide use. Andrew is both a weed scientist and statistician (and, clearly, a data hound) and I really found his take on the data and statisical presentation of forecasted pesticide use in the Benbrook report to be thought provoking.
That blog post and others can be found at ControlFreaks (Wyoming Weed Science) if you are interested.
