Abstract/Contents: | "Fungicides were evaluated as curative agents against dollar spot on a nonirrigated bentgrass + annual bluegrass fairway at the Country Club of Ithaca, NY. The soil is "made land"; soils were mixed and moved to construct the golf course. Treatments consisted of 5 replications of 3 ft x 10 ft plots arranged in a randomized complete block design. Fungicides were applied with a self-powered boom sprayer which delivered 5 gal suspension per 1000 sq ft at 60 psi. The first application was made on 5 AUG when the disease was uniformily affecting about 50% of the turf area. A second application was made on 28 Aug, just before the severely drought-stressed turf began to recover. Treatment areas were rated twice by visually assessing the percentages of area affected by the disease. An analysis of variance on the data from 18 Sep resulted in a significant (P=0.05) F-test. The data was further evaluated with Fisher's least significant difference test. All chemicals tested except CGA 449, Banner, Actidione TGF, and Rubigan AS provided significant curative control of dollar spot. However, only Chipco 26019 50W, DPX H6573, BTS 40542, PP 450, Vorlan, and MF-745 provided aesthetically acceptable control." |
