This study evaluates the effectiveness of four different rates of Wormcast (23 kg, 46 kg, 116 kg and 231 kg/100m2) against two control groups in the suppression and control of snow mold disease in Kentucky bluegrass. Microdochium nivale was inoculated in plots for the initial growth of pink snow mold. Treatments were applied in November before the first snowfall of the season. Phytotoxicity and biotic plus abiotic injury were measured on a weekly basis to measure the total winter injuries that occurred after the snow melted before greenup. No phytotoxic levels were seen in the trial. Due to a lack of snow mold development, this trial was unable to form a conclusion on the effectiveness of the treatments.
