| Abstract/Contents: | "Melting-out of Kentucky bluegrass and Helminthosporium blight of Illahee fescue, caused by Helminthosporium vagans Drechsl. and H. dictyoides Drechsl. respectively, were epiphytotic in Pennsylvania during the 1956 growing season. Complete loss of strands was common, and in many areas, plantings were rendered so undesirable it was necessary that they be re-established. In replicated field tests, Acti-dione, Kromad, Omadine, Captan 50-W, and Terramycin gave highly significant reductions in intesnsity of the leaf spot phase of the disease of Kentucky bluegrass. Yield tests showed Acti-dione, at 1200 mg per 1000 square feet, to cause a temporary reduction in growth of Kentucky bluegrass, while Omadine, Kromad, and Captan 50-W brought about significant increases in yield per plot. None of the materials tested gave satisfactory control of Helminthosporium blight of Illahee fescue. Terraclor, at 4 ounces per 1000 square feet, was extremely phytotoxic on this species, killing approximately 50 percent of the plants in the test areas." |
