Description
Difficult to control perennial broadleaf weed common in thin turf. Seems more common in tall fescue turf than bermudagrass turf. Only found in areas mowed above one inch mowing height. Common weed of greenhouses and in container nurseries due to the explosively dehiscent seed. Chemical control can be difficult often requiring multiple applications of multiple herbicide mixtures.
