| Abstract/Contents: | "A mature stand of perennial ryegrass located on the Spindletop Research Farm near Lexington was used to evaluate eighteen fungicide treatments for rust control. Treatments were replicated four times in a randomized complete block design wit 6 ft x 10 ft plots. The plots were maintained at a 1.5 in mowing height and otherwise given conventional care. A hand-pumped Solo backpack sprayer with a four-nozzle boom delivering 2 gal/1000 sq ft at 25 psi was used to apply the treatments. Application dates were 20 Jun, 5 Jul, 19 Jul, 5 Aug, 20 Aug, and 7 Sep. Wet weather in late summer and again in mid-fall were conducive to rust infection. Plots were rated for rust control by estimating the percent of infected turfgrass foliage. One evaluation was made 11 Sep and the second was done 1 Nov, almost 2 months after the last fungicide application. Rust disease pressure was moderate on 11 Sep and very high by 1 Nov. On 11 Sep, plots treated with Banner, Bayleton, Daconil 2787, and both rates of SN 84363 plus x-77 had significantly lowere rust infections than untreated plots. By 1 Nov only bayleton 25DF, showed a pronounced residual effect resulting in reduction of leaf rust disease." |
