| Abstract/Contents: | "Experiments for control of Fusarium patch (pink snow mold) and Typhula blight (gray snow mold) were performed on predominantly Kentucky bluegrass fairways at the Breckenridge Golf Course, Breckenridge, CO (elev. 9,300 ft) and Vail Golf Club, Vail, CO (elev. 8,000 ft) where snow molds are a recurrent problem. Treatments were arranged in a randomized complete block design with four replications. Individual plots measured 5 ft x 5 ft. Fungicides were applied on 9 Oct 97 (Breckenridge) and 10 Oct 97 (Vail). A CO₂ -powered sprayer equipped with 8003 Tee-jet nozzles delivered the fungicides at 30 psi. All fungicides were applied in the equivalent of 5 gal water/ 1000 sq ft. Light snow fell several days after application; permanent snow cover lasted from late Oct until just prior to evaluations. Fungicide effectiveness was evaluated following snowmelt on 28 Apr 98 at Vail and 13 May 98 at Breckenridge. It was not possible to evaluate the effect of the different pathogens separately. Fusarium patch, snow scald and Typhula blight occurred at both sites. None of the treatments gave satisfactory control of these diseases at Vail. This may have been due to very high disease pressure. At Breckenridge, most combination treatments that included PCNB (Turfcide 400 and Terraguard) or chlorothalonil (Daconil Weather Stik and Daconil Ultrex) gave satisfactory control. When applied alone, PCNB did not control disease nor did other products. The effectiveness of these treatments at Breckenridge may be due to reduced disease pressure. Combinations of Banner, Fore, Eagle and Chipco 26GT combined with PCNB and chlorothalonil continue to perform well under moderate disease pressure at high altitude golf courses in Colorado." |
