| Abstract/Contents: | "Researchers at Colorado State University continue to investigate the distribution and management of snow mold pathogens. Their findings include: Snow mold symptoms become apparent approximately 60 days after permanent snow cover and intensified significantly over the next 30-40 days. Compaction associated with the ski trails lowered temperatures at the soil/snow interface, often to temperatures below freezing, and inhibited snow mold development. Preliminary surveys indicate that Typhula ishikariensis var. ishikariensis is the predominant pathogen on the mountain golf courses above 7,000 feet. Typhula incarnata was most frequently isolated species from sampling locations below 6,000 feet in 2006-2007. All turfgrasses can be damaged to some extent by gray snow mold, but injury is often more severe on perennial ryegrass, bentgrasses, and annual bluegrass. Typhula spp. can vary in sensitivity to chlorothalonil. Although several biological control agents have shown promise as management tools for snow mold, a Trichoderma product did not provide any snow mold control on an annual bluegrass fairway in trials at Vail, CO (elevation 8,600 ft.) and only marginal control on a Kentucky bluegrass fairway at Breckenridge, CO (elevation 9,200 ft.)." |
