The GM crops -- let's look at GM Bt maize and GM Bt cotton here -- are genetically modified to be pesticide (which includes all herbicides) resistant; to be correct, and I'll use one industry brand name here, they are GM Roundup Ready crops.
The crops themselves are not any more resistant to insect or competitive weed infestations, and were in fact designed primarily to be insecticide saturation resistant.
These GM crops were designed to be used in conjunction WITH pesticide use, and that use is increasing dramatically -- not decreasing.
In fact, American farms have applied 318 million more pounds of pesticide over the last 13 years of GM commercially sourced seeds.
In 2008 alone, GM crops required 26% more pounds of pesticide per acre, than fields planted with non-GM seed varieties.
And it's going to get nothing but worse from here on in -- most GM seed varieties are never allowed to naturally mutate and build a resistance to insects.
The weeds the pesticide/herbicides are applied to however, do mutate and have built up an alarming resistance to RoundUp.
This has led to Dow's development of a pesticide which now contains among other chemicals, 2,4-D34 which is a principle ingredient of the defoliant called 'Agent Orange'.
And last year Dow applied to the USDA to commercialize a 2,4-D tolerant GM Corn.
