If you want to kill everything, just add roundup. The mixture of those three products is what no-till farmers use when they have a lot of henbit (purple flowers) coming out of winter. Since the henbit has already flowered and seeded out (think dandelions), roundup does not work that well, as the plant has done its biological function of reproduction, it is not translocation the roundup as well as it would when it is more actively growing. Adding the 2,4-D and dicamba provides the broadleaf weed control without needed to translocation within the plant the way roundup has to.
