jointed goatgrass is a close relative of wheat.
In between crop rotations you can kill goatgrass with round up.
What do you propose the farmers should use to kill
RoundupReady Jointed Goat Grass?
Should we use paraquat instead?
Show us some health or economical analysis please.

Yes, along with the introduction of wheat resistant to other
chemistries. The key to resistance management is the ability to rotate
the chemistries used. And if there is any evidence of resistance
buildup, the herbicides that were used before the age of transgenics can
always be used as needed.
