| Abstract/Contents: | "One protectant and three systemic fungicides were evaluated for control of Puccinia coronata on 'Manhattan' perennial ryegrass. The systemic fungicides more effectively controlled crown rust than the protectant chlorothalonil. This was accomplished at lower rates of active ingredient and with fewer applications. A single late July application of triadimefon at a 2 oz/1000 sq ft rate was more effective than either two ro three 1 oz applications beginning early July. The experimental fungicide diniconazole (XE-779) significantly reduced crown rust prevalence at either the 1 oz or 2 oz rate; however, the 1 oz rate applied only twice was not as effective as three applications of 1 oz or two applications of 2 oz. another experimental systemic fungicide, PP 523, was less effective at 3 oz than at 4 or 6 oz." |
