Who Could Have Pre-, No, Actually Worm Resistence To Bt Corn Predicted 20 Yrs Ago Is Here

6. "Bt was used....more than 40 years without observable resistance"

Why was this, you ask?

The answer is simple: organic farms comprise such a small amount of actual farmland that any resistance developed by the local population would quickly be diluted and nullified by continuous breeding with the non-Bt treated conventional fields (this was before Bt crops were introduced). With only a fraction of the insect population being exposed to Bt, continous interbreeding with non-Bt resistant populations from neighboring farms, and Bt resistance conveying no survival benefits outside the few organic farms in existence, the answer is very clear why we never saw Bt resistance before GMO's incorporated it.

It's also pretty much EXACTLY what has been proposed for the past 20 years to prevent this very sort of thing from happening: the planting of crop refuges to stop resistance from arising.

The problem is that, given the scale of GMO cultivation, the paltry area of refuge crops planted have had little effect.
