> Contrary to often-repeated claims that today’s genetically-engineered crops have, and are reducing pesticide use, the spread of glyphosate-resistant weeds in herbicide-resistant weed management systems has brought about substantial increases in the number and volume of herbicides applied.
The linked paper does say insecticide use went down, but herbicide use went up.
> Overall, pesticide use increased by an estimated 183 million kgs (404 million pounds), or about 7%.
That said, I’d be surprised if GMO really has managed to reduce pesticide usage. I’m pretty skeptical of big-tobacco-like scientific studies. Do you know of a good study that shows this, and which isn’t funded by Bayer or some similarly motivated company?
