| Abstract/Contents: | "When grown under watering practices that allowed the soil mass to be extracted to the permanent wilting percentage before being wetted back to field capacity, the susceptibility of Kentucky bluegrass to Sclerotinia dollar spot and of Highland bentgrass to Pythium blight was increased two fold. The Rainier variety of creeping red fescue, grown under a similar cyclic watering pattern, was more resistant to Corticium red thread than plants grown at constant field capacity. The susceptibility of Seaside bentgrass to Rhizoctonia brown patch, of the Merion variety of Kentucky bluegrass to Fusarium blight, and of the Pennlawn variety of creeping red fescue to Corticium red thread was not altered by soil moisture levels in the field capacity to permanent wilting percentage range. Interpretation of the influences of nutrition on turfgrass disease development and the utilization of knowledge of known relationships in disease prognosis is complicated by the high degree of interactions among nutrition, pH, nutritional imbalances, soil moisture, soil temperature, air temperature, plant genotyoe and season of plant growth. Where individual nutrient elements are concerned, nitrogen and calcium appear to exert the most profound influence on disease susceptibility of turfgrass. In this relationship nitrogen appears to be the least stable of the two. With few exceptions, plants grown under calcium deficient nutritional programs were more susceptible to disease than those under normal calcium nutrition and this plant reaction was not altered by the introduction of nutritional imbalances, varying soil and air temperatures and different plant genotypes." |
