| Abstract/Contents: | "Seventy-two cultivars and selections from the 1985 National Kentucky Bluegrass Test were established in Sep 1985 at the Landscape Management Research Center, University Park, PA. The plots were 1.2 x 1.8 m and were seeded at a rate of 1 kg per 100 m2. All entries were replicated three times and arranged in a randomized complete block design. The turf was mowed at approximately 4.5 cm, fertilized with 0.7 kg N per 100 m2 in late spring, and treated with a combination of 2,4-D/MCPP/dicamba to control broadleaf weeds. No fungicides or insecticides were used during the course of this test. The test site was not irrigated prior to the leaf spot rating. A uniform infestation of leaf spot disease occurred at the site in May 1990. The plots were visually rated on 8 May 1990 for percent disease injury using a modified Horsefall-Barrett scale. Significant differences were found in the resistance of Kentucky bluegrasses to leaf spot disease. However, most cultivars and selections showed good resistance (less than or equal to 5% of the plot area injured by leaf spot). Cultivars that showed the most leaf spot injury included `Kenblue',`South Dakota Certified', and `Wabash'." |
