Has anyone used this? It is 4lb material of Dicamba. My local BWI is having a closeout on it for $59 for 2 1/2 gallons. A person could make a whole lot of 2-way or 3-way with 2 1/2 gallons of dicamba and cheap. Has anyone heard anything bad about this product? I paid $215 for a jug of Clarity this year and the price on this Diablo seemed to good to be true.
