| Abstract/Contents: | Dr. R. W. Smiley of Cornell University has reported the identification of two fungi (Leptosphaeria korrae and Phialophera gramincola), that he suggests produce the same symptoms as Fusarium blight syndrome (which Smiley differentiates from Fusarium blight--a crown and root disease caused by Fusarium fungi). This apparent identification is advantageous in developing disease control. Yellow ring, a disease of Poa pratensis, caused by the fungus Trechispora alnicola, is the second species of Trechispora reported to attack turfgrass. The other, T. confinis, attacks only Agrostis stolonifera subsp. palustris. T. alnicola is primarily a saprophyte, capable of breaking down thatch. Therefore having both a useful ecological niche and a deletreious esthetic effect. Research is being conducted to determine why a saprophytic fungus will, under certain circumstances, parasitize P. pratensis roots; also, preliminary research has demonstrated a reduction in both pathogen activity and the development of yellow ring symptoms when treated with pentochloronitrobenzene. A zoysia disease (temporarily called Zoysia patch) has been observed and research efforts are attempting to identify the cause and develop a treatment. The disease is characterized by 4-5 diameter patches of dead grass, appearing at the spring breaking of dormancy and the fall slowing of growth. Two potentially major problems for spring are winter desiccation and snow mold causing fungus. |
