| Abstract/Contents: | "Snow mold management field trials for the fall/winter of 1998 were conducted on naturally infested nursery turf stands at Northland C.C., Duluth, MN and Giants Ridge G.C., Biwabik, MN. Field studies were set up as randomized complete block design with three replicates per location. The plots at the Duluth locatoin were 3' x 8.5' whereas those at Biwabik were 6' x 7'. Spray treatments were applied with a CO2 back-pack sprayer at a pressure of 30psi to deliver a total volume of 2 gallons water per 1000ft². Granular treatments were applied to plots by hand. Initial applications at both locations were applied 27 October 98. Six additional treatmens were applied on 3 November 98. Treatments requiring a second application were applied 24 November 98, however, second treatments were only applied at Duluth because the plots in Biwabik were inaccessible due to snow cover. The plots were rated on 5 April 99 shortly after snow cover had melted from the turf plots. Disease ratings were recorded as the percent of plot infected with snow mold. Snow cover in the early winter was delayed due to unseasonably warm weather at both locations (17 November at Biwabik, MN, and December 12 at Duluth, MN), however, snow cover was sufficient for disease development. The primary pathogen responsible for snow mold disease at both locations was Typhula ishikariensis with some T. incarnata being identified at the site in Biwabik, MN. Untreated control plots in Biwabik, MN averaged 55% infection, however, this infection varied between replicates as 85%, 70% and 10% infection. The third replicate of the study, with the lowest disease level, was mowed to a lower height (from 0.5 in. to 0.25 in) in the fall prior to snow cover, which may account for lower disease levels. Untreated control plots at the Duluth, MN location averaged 75% grey snow mold infection. Disease pressure was uniform over the three replicates of this study." |
