Interesting piece suggesting that poor farming techniques may be restricting the effectiveness of (GM) BT-CORN.
As I have said before GM is not the answer, it is one small part of the answer, depending what the question is of course.
We still must use the good husbandry techniques developed over time – rotations, soil management, varieties (inc GM at times) and yes pesticides.
Using new technologies is not the be all and end all, we should still be farming in fairly traditional ways but utilizing new methods and innovations.
