I've got some torpedograss in my lawn and gardens. The greenery diea away easily with glyphosate but is difficult to totally eradicate in one dose as it has large rhizomes. The addition of the imazapyr would help get a better kill.
will imazapyr kill the aquatic plants..
I planted a few red ell grass springs IM trying to nurse along...
Also do you mix the two or do at dirrerant times...
