> Folks: "killer weeds" - is this not Striga? I seem to recall hearing
> reference to how GE was somehow going to do away with Striga, which is
> indeed a real curse in Africa. It is one of several parasitic plants,
> which live off of other plants, and have a special
> liking for certain key crop plants. The seed of Striga has evolved a
> really clever scheme for germinating in response to certain chemicals
> given off by only the germinating seed of target host plants (not others).
> Then, it has I think 4 days in which to grow out and contact the host
> roots for invasion, or else it dies. So, the seed can stay dormant for a
> long time, waiting for the crop to return, and when it does - whammo.
> I think I have the story right, but what I'm unclear on is how GE is going
> to kill the killer weed, particularly on the land of subsistence farmers
> who don't purchase seed or other inputs anyway.
