• Grass Mixtures for Seeding Sagebrush Lands

      Hull, A. C. (Society for Range Management, 1971-03-01)
      Four wheatgrasses were seeded alone and in mixtures in 1945 near Dubois, Idaho. By 1955, fairway wheatgrass had spread by seed to all plots and has remained the most abundant species. Intermediate and pubescent wheatgrasses spread slower, mainly by rhizomes, and by 1967, they were present on all treatments. At the end of 25 years these three species are growing well together. Bluebunch wheatgrass has practically disappeared from the study area.
    • Spraying Tarweed Infestations on Ranges Newly Seeded to Grass

      Hull, A. C. (Society for Range Management, 1971-03-01)
      A high elevation, tarweed-infested range which had been newly seeded to grass was sprayed with 3 rates of 2,4-D at 2 growth stages of the seeded grass. 2,4-D at 0.5 lb./acre killed over 97% of the tarweed and 1 and 2 pounds killed 99 and almost 100, respectively. Rate of spraying when grasses had 1 to 2 leaves did not affect numbers of grass plants but killed more tarweed than did spraying when grasses had 2 to 4 leaves.
