I told you I had objections to herbicide resistant GM, you said it seriously reduced the use of pesticides. You then provided a link that shows that no, it doesn't. If you look at Table 2 in the paper, in the column for GM crops with 'herbicide tolerance', you'll notice that pesticide use actually increases for those crops as opposed to traditional crops. The GM crops in which pesticide use actually decreases are those that have insect resistance, ie, the Bt crops, not the RoundUp Ready ones. I do agree that that table does point out that using GM, even 'herbicide resistant' GM makes farmers a lot more money, but then I also pointed out that people often choose how and what to plant based on monetary choices.

Now if I did make a mistake, it was in underestimating the ratio of Bt crops to RoundUp ones. Given the way in which the 'All GM' column is massively skewed towards the 'insect resistant' values rather than the 'herbicide tolerance' values, there's obviously a heck of a lot more Bt GM out there than I thought.
