| Abstract/Contents: | "Dollar spot caused by Sclerotinia homoeocarpa is one of the most important diseases of turfgrass. Although variable, previous research has shown that fungicide application to asymptomatic turfgrass in the fall and/or spring may reduce dollar spot severity the following season. Replicated field studies were established at two locations in 2006 and 2007 to determine the relationship between climatic conditions at or surrounding the time of fungicide application with the ability of imposed treatments to suppress the development of dollar spot later in the season. Weather monitoring stations were used to record on-site climate conditions. Sequential applications of propiconazole and chlorothalonil as a combination treatment were applied in the fall and spring of each year to asymptomatic turf. Disease severity was assessed by counting dollar spot infection centers and using digital imagery analysis. Areas under disease progress curves were calculated and the differences among treatments determined. Fall fungicide applications had no impact on disease severity the following season. The lack of consistent disease suppression observed with the fall fungicide applications in this study is consistent with previous reports. Applications made in late March to early April in both years of the study resulted in significantly less dollar spot. The relationship between climatic conditions at or surrounding these early spring fungicide applications will be discussed." |
