Can herbicide tolerant genes move from crops derived through biotechnology into weeds and create “superweeds?”
Herbicide tolerant genes can move from some crops to certain weedy relatives in some locations, but this will not necessarily lead to the creation of superweeds. Weedy relatives might acquire tolerance to a specific herbicide, but if the weedy relative is not treated with that herbicide, then having the new gene offers no competitive advantage. Even though the weed may no longer be susceptible to that herbicide, it can be controlled with a number of other herbicides.
