| Abstract/Contents: | "A field study was conducted in AugĀSep 2007 to determine the influence of nozzle type and water volume on the control of dollar spot, caused by Sclerotinia homoeocarpa. Plots were 1.5 x 1.5 m and were arranged in a randomized complete block design with four replications. Chlorothalonil (4.5 kg ai/ha) was applied on a 14Ād interval with the following treatment variations. The nozzle types included were: XR TeeJet, TurfJet, Air Induction TeeJet, Turbo TwinJet, and Turbo Drop Twin Fan. Pressure was kept constant at 276 kPa, and for each nozzle type, three flow rates (ex: XR11002, XR11004, and XR11008) were used to produce water volumes equivalent to 206, 412, or 824 liter per/ha. Disease was assessed every 10Ā20 days by counting the number of dollar spot infection centers in a 0.4 x 0.4 m square in the center of each plot where coverage was complete. On two rating dates there were no significant differences among any treatments. On the third rating date, all nozzleĀvolume combinations reduced disease significantly compared to the untreated controls except for the TurfJet nozzles at the lower water volumes (TJ02 and TJ04). There were no significant differences among water rates for any other nozzles. These results show that nozzle selection can affect dollar spot development, and some nozzles can be paired with low water rates without compromising disease control." |
