Abstract/Contents:"Dollar spot (Sclerotinia homoeocarpa F.T. Bennett) is a major disease of turfgrass in the United States. The pathogen is believed to overwinter as mycelium or stromata in previously infected tissues or in dead or decaying plant material in the thatch. The ability to reduce S. homoeocarpa inoculum with fungicides applied early in the season was assessed on a Connecticut golf course fairway in 2006 and 2007. Various fungicides were applied on 13 April 2006 and 24 April 2007. Treatments were initiated after the second spring mowing and approximately 4 to 6 weeks prior to the appearance of dollar spot symptoms. In 2007, the influence of post-application irrigation was also assessed. Disease suppression was determined by visually assessing the percent dollar spot per plot (1.6 or 2.3 m2). Disease pressure was considered high in both years and untreated plots had an average of 33% and 21% dollar spot on the final rating dates in 2006 and 2007, respectively. When compared to the untreated control, dollar spot was reduced 48% to 67% for up to 5 weeks after the appearance of initial symptoms in 2006. In 2007, percent dollar spot was reduced between 68% and 87% for approximately 6 weeks after initial symptoms appeared. Post-application irrigation did not positively or negatively influence the fungicides' ability to suppress disease. Results of these field experiments suggest that S. homoeocarpa may be active in the thatch, soil or living plant tissues for up to 1 month prior to the appearance of dollar spot symptoms."
