The turf was maintained at a 0.25 in. mowing height, received minimum nitrogen fertilization, and otherwise received conventional maintenance. Each treatment was replicated four times in a randomized complete block design with 6 ft X 10 ft plots. Treatments were applied using a hand-pumped Solo backpack sprayer with a 6 ft four nozzle boom delivering 2 gal/1000 ft2 and operating at 25 psi. Application dates for all treatments were 24 May, 7 Jun, 21 Jun, and 9 July 1985, except FMC 4921 which was only applied on 24 May. Plots were evaluated 12 Jul by counting the number of infection centers/plot. No disease symptoms were observed at the start of the test, however, disease pressure was heavy by the time the plots were evaluated. All treatments except CGA 449 had significantly less dollar spot infections than the untreated plots. Four treatments, Banner 1.1E, Bayleton 25 DF, and two rates of (3.0 and 4.5 ounces per 1000 feet squared) Prochloraz 40 EC plus Actidione TGF completely prevented dollar spot disease symptoms.
