Abstract/Contents:Presents research conducted "to answer two questions: (1) is it possible to make fungicide applications on healthy turfgrass during the previous fall and/or early spring and control diesase outbreaks the following season, and (2) if it's possible to deploy fungicides in this manner, when is the best time to make such applications." Explains that "dollar spot, caused by the fungus Sclerotinia homeocarpa, is one of the most economically important diseases of cool-season grasses. It's routinely cited as the most sprayed for turfgrass disease and typically tops the list of golf course diseases most difficult to manage." Details methods and materials used in the study, stating that "treatments in this study included single fall...and single spring...applications of propiconazole (two rates used - 1.0 ounce of Banner Maxx from Syngenta per 1,000 square feet and 2.0 ounces of Banner Maxx per 1,000 square feet), chlorothalonil (3.2 ounces of Daconil Ultrex from Syngenta per 1,000 square feet), thiophanatemethyl (2.0 ounces of 3336 F from Clearly per 1,000 square feet), iprodione (4.0 ounces of 26GT from Bayer per 1,000 square feet) and an experimental compound (0.2 of an ounce of BASF 505 from BASF per 1,000 square feet)." Reports that "fall and spring applications of fungicides significantly reduced disease the following season."
