Three experiments were conducted to evaluate the effects of preemergence-applied herbicides on growth of liriope [Liriope muscari (Decne.) L.H.

Surflan (oryzalin) and a Surflan + Gallery (isoxaben) combination inhibited root and shoot growth. Predict (norflurazon) caused foliar injury characterized by bleached bands or spots on both old and new foliage.
