I really shouldn't answer this, but Ill take a swag from long lost memories.

Supposedly there was is a plant somewhere that glyphosate won't touch.   Isolate the gene from that plant and throw it in another.   Now in another ten years, maybe less, many more weeds (plants) will grow tolerant to it to glyphosate through natural selection.

If only us farmers were able to adapt as quick as bugs and plants, we'd have it made!

Again, this is just a swag, feelin chatty tonight.
