Well its time to fight dallisgrass down south. Pulled out the old hose rig and treated the most severe accounts as usual (1.75 gallons/K), but spent the whole time wondering if my zspray could have done the job as well(or safe)---definitely easier. So I have begun to experiment. I treated a couple of tif 419 ballfields @20GPA water +3 lbs. msma/ac.---with some burn but not prohibitive. I am now moving to the #6 tips to treat at 30 GPA. So far so good. Dallisgrass control appears good and burn minimal. Second application should definitely be okay with the z at a lighter rate of msma. Common bermuda tolerance has been better than the 419. Any other comparable results out there would be appreciated.
