| Abstract/Contents: | "Dollar spot, caused by Sclerotinia homoeocarpa, is the most important turfgrass disease in the United States with respect to fungicide expenditures. Single early-season fungicide applications delay dollar spot symptom development, but do not provide season long control of the disease. This field study compares the efficacy of a conventional dollar spot fungicide program to early-season programs. This study was conducted at the O.J. Noer Turfgrass Facility and at Milwaukee C.C. in Wisconsin. Conventional applications started June 1 and were applied on 14-day intervals using full label rates of propiconazole and chlorothalonil. Early-season treatments were applied May 1, followed up with applications of a tank mixture of propiconazole and chlorothalonil at either ¾ rates every 21 days or full label rates applied on 28-day intervals. Treatments were arranged in a randomized complete block design with four replications with individual plots measuring 2.8 m2. Disease severity was rated visually by counting individual dollar spot foci every two weeks. The 21-day early-season program suppressed dollar spot development, but not to acceptable levels (<5% disease severity). The 28-day early-season program provided an excellent suppression that was comparable to the conventional program. One fungicide application could be eliminated by using a 28-day early season program rather than a 14-day conventional program, reducing fungicide expenditures and environmental inputs." |
