Abstract

Stipa clandestina Hackel, a native of northern Mexico, has been found in Texas and may become a serious weed problem for range managers in the southwest. Its sharply pointed leaves and tussock-forming habit make it unpalatable to cattle, but in Mexico it tends to increase with heavy grazing or disturbance. Actively growing plants can be killed by applying a foliar spray of either glyphosate or hexazinone.
