But if you are resolute about eradicating the clover mixed in with your turf grass, there are both chemical and organic means to do so. For the former, seek a broadleaf herbicide intended for use on the type of grass that you’re growing (study the label on the bottle carefully). Along with other broadleaf weeds, clover will also be killed by such herbicides.
