I am trying to kill quackgrass and barnyard grass in a bluegrass lawn with a little fall fescue. Do I use the 6oz per acre? That seemed to be what they recommend on the label for use on a tall fescue lawn.
Fusilade II Herbicide should not be used on desirable turf as a broadcast spray. You can do a spot treatment in your lawn only. The mixing ratio is 0.75 fl. oz. per gallon of water. It is also recommended that you use a surfactact, such as the Non-Ionic Surfactant. The mixing ratio for that is 1/2 fl oz.
