| Abstract/Contents: | "Creeping bentgrass is a popular fairway turf in the North Central Region of the USA. Creeping bentgrass is very susceptible to dollar spot (Sclerotinia homoeocarpa F.T. Bennett). In the USA golf course industry, more money is spent to control dollar spot than any other disease. To develop needed information on integrated systems approaches for dollar spot management in creeping bentgrass, a field study was initiated to determine the effects of irrigation regime, creeping bentgrass cultivar, fungicide treatment interval and N-rate on turfgrass dollar spot severity and quality. Fungicide treatment interval and N-rate significantly influenced dollar spot severity and fungicide treatment of 7 and 28 days when compared to the untreated control, and the 7-day interval was significantly better than 28 days. However, the 28-day treatment did improve turfgrass quality compared to the untreated control. Turf fertilized with 30 g N m-2 season-1 in the absence of fungicide treatment, also had less disease and higher quality than turf fertilized with 15 g N m-2 season-1 on certain evaluation dates. Fungicide treatment interval had the greatest impact on turfgrass quality and dollar spot incidence of the factors studied. Irrigation regime and cultivar had no significant impact on turfgrass quality or dollar spot incidence under the conditions of this study. This approach provides a foundation for dollar spot management on a creeping bentgrass fairway by showing that fungicide treatment intervals can be extended with higher N-rates. An integrated dollar spot management program can then be developed using N-rate and fungicide treatment interval as a starting base." |
