| Abstract/Contents: | "A major constraint for bluegrass (Poa pratensis) seed production, and foreign marketing, is ergot caused by the fungus Claviceps purpurea. Currently, the only method of ergot control is open-field burning following harvest. This practice may be eliminated in the future. In 1990, following bluegrass harvest, machine, open-field, and no burn treatments were applied in the fall to determine their efficacy for controlling ergot. Ergot sclerotia harvested in July 1990 were put in stainless steel wire mesh packets and were placed at the soil surface, and at 1-cm and 3-cm soil depths. Temperature data were collected and sclerotia were tested in the laboratory for viability. Peak temperatures for machine burn were 200 C greater than those for open-field burning. Germination of sclerotia placed at the soil surface was 1,10, and 52% for machine, open-field and no burn treatments, respectively. There were no treatment effects on sclerotia placed at 1-cm or 3-cm soil depths." |
