Effect of Snow Removal on Typhula Blight Development at High Elevation Golf Courses in Colorado

Fig. 3. Seasonal development of Typhula blight in non-fungicide treated plots on an annual bluegrass and Kentucky bluegrass fairway at Vail and Breckenridge, CO, respectively, in 2006-2007. Shaded area of graph represents the period of snow cover beginning on 14 November 2006 and ending on 20 March 2007. Typhula blight damage on all sampling dates with snow cover was determined by removing turf cores and estimating plot damage based on injury to the cores. Bars represent standard errors for each mean.
