I read on the Texas Department of Agriculture's website that the Herbicide "Maverick" is available for use in established Bermuda Pastures & Hayfields under Section 18 (Expires June 30, 2008)

I had good success last year killing the Johnson Grass in my coastal hayfield by spraying Maverick at a rate of 1.3 oz per acre. Also, each year I've been spraying Grazon P+D for the broad leave weeds just after greenup. My question is "Can I mix these two chemicals in the same tank and spray them together in one application?" The Johnson Grass seems to be growing at a faster rate this year than last year at this same time. I'd like to be sure and knock-it-out soon, since it is already around 12" high. I just want to be sure there isn't any problems using both Maverick and Grazon together. Please advise.
