• Comparative Susceptibility of Honey Mesquite to Dicamba and 2,4,5-T

      Scifres, C. J.; Hoffman, G. O. (Society for Range Management, 1972-03-01)
      Applications of dicamba controlled about the same percentage of honey mesquite (Prosopis glandulosa Torr., var. glandulosa) as equivalent rates of 2,4,5-T in the Rolling Plains, Coastal Prairie, and South Texas Plains. Combinations of 2,4,5-T and dicamba controlled no more honey mesquite than either herbicide alone. Honey mesquite control was governed by total herbicide applied rather than relative proportions of 2,4,5-T and dicamba in combination. Dicamba was effectively substituted for 2,4,5-T in combinations with picloram. Three-way combinations were no more effective than mixtures of dicamba and picloram or 2,4,5-T and picloram.
    • Sand Shinnery Oak Response to Dicamba Granules and Picloram Pellets

      Scifres, C. J. (Society for Range Management, 1972-03-01)
      Two lb./acre of picloram pellets were required to reduce sand shinnery oak (Quercus havardii Rydb.) stem density one season after application in the Rolling Plains of northwest Texas. Neither picloram pellets nor dicamba granules reduced the density of live sand shinnery oak stems two years after application.
