| Abstract/Contents: | "The experiment was conducted at the Valentine Turfgrass Research Center, University Park, PA, on Kentucky bluegrass mowed three times per week at a cutting height of 2-in. The soil was Hagerstown silt loam with a soil pH of 6.8. The test area was fertilized with 0.5 lb nitrogen (Urea 46-0-0) per 1,000 sq ft on 24 April. Treatment plots, 3 ft x 6 ft, were arranged in a randomized complete block design with three replications. Fungicides were applied with a CO2-powered sprayer, using a TeeJet 11008E nozzle at 40 psi, in water equivalent to 2 gal per 1,000 sq ft. Applications were made curatively on 3, 17, and 31 May. Assessment of the spring leaf spot incidence (% leaf blades symptomatic) was made on 9 May, and subsequently spring leaf spot severity (index 0 to 10; 0=turf asymptomatic; 10==90% turf area symptomatic) assessment was made on 14, 22, and 28 May, and 4 Jun. Data were subjected to analysis of variance, and the mean values were separated using the Waller-Duncan k-ratio Test. Spring leaf spot development in the Kentucky bluegrass in the experimental area was slow in early stage of disease development under cool and wet conditions. Severity of the disease was relatively low (less than 1 in untreated control plots) in early May, and disease incidence data was collected during the early period of the experiment. Disease pressure increased over time in mid-May and the first assessment of disease severity was made on 14 May. In the first assessment of disease severity, several fungicides provided satisfactory control of the disease. Several fungicides provided good to excellent control during the course of the experiment. No phytotoxicity was observed in any of the treatment plots." |
