Take-all patch is a serious disease of St. Augustinegrass and can also cause problems in bermudagrass. The first symptom is often a yellowing of the leaves and a darkening of roots. Unlike brownpatch, the leaves of take-all infected plants do not easily separate from the plant when pulled and the stolons will often have discolored areas with brown to black roots. The roots are sometimes so rotted that damaged stolons are easily pulled from the ground.
