Abstract/Contents: | "Application of six nitrogenous fertilizers reduced the intensity of yellow tuft disease symptoms in a heavily infected 'Jamestown' chewings fescue 'Kingstown' velvet bent sward. Reduction of disease symptoms by the fertilizers was ascribed to improved colour and density afforded by nitrogen. Nutrients applied to a sand medium supporting plants infected with S. macrospora enhanced the spore producing capacity of the mycelium contained within these plants. Fertilizers, therefore, masked disease symptoms, but did not cure the disease. Greenhouse tests showed that the experimental fungicide CGA 48988 (trade name Subdue or Ridomil) arrested any further mycelial colonization of developing leaves and rhizomes from crowns of infected Kentucky bluegrass plants. SN-66752 (trade name Previcure) had no curative fungicidal activity against S. macrospora. Field testing revealed that CGA 48988 + Daconil 2787F combination provided exceptional curative control of yellow tuft disease. 'Jamestown' chewings fescue plants, infected by S. macrospora, persisted for a minimum of two years. Developing axillary buds can escape systemic invasion of mycelium from infected crowns and eventually those downy mildew free tillers may replace the original, diseased plant. This may account for the ephemeral nature of this disease." |
