Abstract/Contents:"Sixty-five cultivars and experimental selections were established in Sep 1986 at the Joseph Valentine Turfgrass Research Center, University Park, PA. The treatments consisted of entries in the 1986 National Perennial Ryegrass Test. The plots were 1.2 x 1.8 m and seeded at a rate of 2.5 kg per 100 m2. All entries were replicated three times in a randomized complete block design. The turf was mowed at 1.3 cm and treated with a combination of 2,4-D/MCPP/dicamba to control broadleaf weeds. The test was fertilized with 0.5 kg N per 100 m2 in Apr 1990, and received no fungicide or insecticide applications. The test site was irrigated when necessary to prevent drought stress. A uniform infestation of dollar spot disease occurred in Aug 1990 and the plots were visually rated for disease injury on 20 Aug 1990. Significant differences were found in the resistance of perennial ryegrasses to dollar spot disease. ` Repell', `Belle', `Caliente', and `PSU-222' showed the least amount of dollar spot injury."
