Not sure which without looking it up, but some of the grass chems for beans can be used in clover to remove the Johnsongrass. Mutliple spraying will be needed and even then, remember that seed can lay in the ground for years. Don't be surprised if you break it up later and it looks like it is a Johnsongrass patch again.
