• Grass Seedling Emergence and Survival after Treatment with Fungicides

      Hull, A. C.; Kreitlow, K. W. (Society for Range Management, 1971-09-01)
      Thiram, Captan and Semesan were used to treat seeds of intermediate wheatgrass, tall oatgrass and smooth brome, seeded in spring and fall for 5 years, and to treat seeds of crested and intermediate wheatgrasses seeded for 3 years at a second location. The same fungicides were used to treat grass seeds at 3 rates in two studies in the greenhouse. Kind or rate of fungicide treatment did not significantly influence seedling emergence in the greenhouse. Averaging the two field areas, Thiram treatments gave significant increases over the check of 14% in emergence and 20% in survival. Captan treatments gave significant increases of 12% in emergence and survival. Semesan increases were not significantly better than the check.
