| Abstract/Contents: | "Fungicide treatments were evaluated for the control of pink snow mold and Typhula blight in separate trials at the University of Massachusetts Turfgrass Research Facility in in S. Deerfield MA. The creeping bentgrass cultivar Penncross was established in 1979 on silt loam soil and maintained at a mowing height of 0.25 in. No fertilizers or pesticides were applied after Sep, 1991. Two identical experimental areas were established. Plots were 3 ft x 3 ft, and treatments were arranged in a randomized complete block design with four replications. Fungicides were applied to each area with a CO2 backpack sprayer at approximately 30 psi and at a rate equivalent to 3 gal of water per 1000 sq ft. Fungicides were applied on 19 Nov. After fungicides had dried on the turf foliage, approximately 1.6 oz of autoclaved wheat grain infested with Microdochium nivale were evenly distributed on each plot of the pink snow mold experimental area. Autoclaved wheat grain (1.6 oz) infested with Typhula incarnata were evenly distributed on each plot of the Typhula blight experimental area. Each area was covered with straw to a depth of 6 in. To prevent wind removal of the straw, each area was covered with a shade tobacco cloth which was staked at the perimeter. The winter months were relatively mild with little snow. The experimental areas were raked free of straw on 3 Mar after the final snow had melted. Counts of disease foci were made 56 10 Mar. Disease foci were approximately 1.5 in. in diameter. Typhula blight was observed only in the nontreated plots of the experimental area inoculated with T. incarnata. Disease foci in the nontreated plots numbered 55, 38, 46, and 38. All fungicides tested provided complete control of Typhula blight. Pink snow mold was observed only in the experimental area inoculated with M. nivale. Excellent control was provided by CGA17306 at all rates tested and by Banner, Sentinel, SAN 832F, and some rates of ASC66825. Several standard fungicides failed to provide adequate control at the rates evaluated and under the disease-conducive conditions of the experiment." |
