Since they have different compositions, can I used the max rate for both, or do you recommend to reduce the rate? Any other recommendation for split treatment ?
Barricade and Dimension are actually in the same class of herbicides which means they work with the same mode of action for most of the same weeds and there would be no benefit to using each so close together. It is more recommended to rotate each season between different actives to prevent resistance buildup. Typically Dimension is more recommended in the spring as it is best for crabgrass and has early post emergent control of it as well (in a separate application). Using the max rate in one season would prevent you from using either in the fall which is also a recommended time for pre-emergent applications for winter/spring weeds.
