I have used alot of armezon/impact the last 5 years and it is poor(at best) on panicum and fair/poor on other grasses. I see alot of posts lately about armezon/impact, if you guys plan to use it with any product that includes dual and gly, good luck on keeping your sprayers from plugging. Plenty of guys in this locale had trouble the last two years with their premixed halex, let alone mixing their own.
