Abstract/Contents:"An evaluation of fungicide treatments for control of red thread (Laetisaria fuciformis) and pink patch (Limonomyces roseipellis) was conducted at the Landscape Management Research Center, University Park, PA, on 'Koket' chewings fescue (Festuca rubra ssp. commutata 'Koket') maintained under home lawn management conditions. Individual plots, 3 ft x 23 ft, were arranged in a randomized complete block design with three replications. Treatments were applied with a CO2-powered boom sprayer, using T-jet 8004 nozzles, at 30 psi, in water equivalent to 2 gal per 1000 sq ft. Applications were made on 8 and 22 May and 4 and 18 Jun, except as noted in the table. Red thread/pink patch were visually evaluated on 3 and 26 Jun. Data obtained were subjected to analysis of variance and Duncan's Multiple Range test. Although statistical separation of these data was poor, most of the chemicals tested provided red thread/pink patch control that was significantly different from the check. On 26 Jun, plots that had been treated with Daconil 2787 were so badly damaged by necrotic ring spot that rating for red thread/pink patch severity was not possible. There were no symptoms of necrotic ring spot present at this time in any other treatment or the check. Examination of the roots of the fine fescue plants from the Daconil-treated plots revealed extensive proliferation of dark ectotrophic hyphae."
