Abstract

Three experiments were conducted to evaluate the effects of preemergence-applied herbicides on growth of liriope [Liriope muscari (Decne.) L.H. Bailey ‘Big Blue’ and ‘Variegata’] when applied immediately after division. Overall, most herbicides caused no injury or suppression of root or shoot development. 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.
