Ukitake's Bankai hasn't been revealed yet, only his shikai has.
he does he says "shoot to kill, shinso" and it literally shoots to kill. i don't know if that is his bankai or if his bankai is when his sword turns to dust. The sword pieces have poison in them, so they kill the opponent...i dunno which one is the actual bankai, but i hope it helped :)
