Improved Strategies for Dollar Spot Suppression Using Ferrous Sulfate
Dollar spot is one of the most common diseases of warm- and cool-season turfgrass stands and is especially devastating on creeping bentgrass (Agrostis stolonifera L.). The fungus Sclerotinia homoeocarpa degrades the foliage by creating silver, dollar-sized depressions of dead and bleached turf. …

Evaluation of bacterial strains for control of dollar spot on creeping bentgrass and brown patch on tall fescue
… homoeocarpa F.T. Bennett, causal agent of dollar spot on creeping bentgrass (Agrostis palustris Huds.); and Rhizoctonia solani Kihn, causal agent of brown patch on tall fescue (Festuca arundinacea Schreb.), are important pathogens of turfgrass. This research evaluated the ability of twenty …

Evaluation of fine fescues as alternative golf course fairway turfgrasses
… creeping red fescue was more susceptible to dollar spot disease (caused by Sclerotinia homoeocarpa F.T. Bennett) than the other species. The third experiment evaluated fine fescue species and mixtures for snow mold resistance on three golf courses in Minnesota. In the spring of 2013, 2014, …
