Many landscapers and growers with herbaceous perennials (HP) still rely upon hand-weeding. The previous lack of herbicide registrations in HP crops (including ornamental grasses) has perpetuated fears that herbicides cause injury. These previous labor-intensive control programs have constrained growth in this industry sector. However, recent research efforts have expanded herbicide labels to include HP species. Dramatic improvements in HP weed control will be discussed.
