Acclam Extra Selective Herbicide already controls crabgrass so mixing in the 3 Way Max would not help you get any control over crabgrass. 3 Way Max is a broadleaf weed control product and if you needed to use this it would need to be done in a separate application. Please Note: Broadleaf herbicides such as 2,4-D or MCPP may reduce the effectiveness of Acclaim Extra Herbicide. Do not apply Acclaim Extra within 21 days following a 2,4-D or MCPP application, or 5 days before a 2,4-D or MCPP application.
