GMO crops mean MORE herbicides

"One of the main arguments behind creating these engineered crops is that farmers then need to use less herbicide and pesticide. This makes farms more eco-friendly, say proponents of genetically modified (GM) crops, and GM seeds also allow farmers to spend less on “inputs” (chemicals), thereby making a greater profit.

"But a new study released by Food & Water Watch ... finds the goal of reduced chemical use has not panned out as planned. In fact, according to the USDA and EPA data used in the report, the quick adoption of genetically engineered crops by farmers has increased herbicide use over the past 9 years in the U.S. The report follows on the heels of another such study by Washington State University research professor Charles Benbrook just last year.

"Both reports focus on 'superweeds.' It turns out that spraying a pesticide repeatedly selects for weeds which also resist the chemical. Ever more resistant weeds are then bred, able to withstand increasing amounts – and often different forms – of herbicide." -- Forbes
