Nearly all GMO plants out there are engineered to resist some kind of poison (herbicide or pesticide) so people can spray more of it.

The one rare GMO plant engineered to require less poison spraying nearly always does that by producing the poison itself, and having it in large amounts on every tissue. I wouldn't want to eat that stuff pretending that it's an improvement, thank you.

There exist some odd research GMO that resist bugs or require less herbicides due to some effect that does not involve producing poison. I haven't heard of any that left the lab, but I imagine it's possible there is some commercial crop of something like that somewhere.
