| Abstract/Contents: | "This evaluation was conducted at Wawonowin Country Club in Champion, MI on a creeping bentgrass and annual bluegrass fairway maintained at a height of 0.5 in. Individual plots measured 3 ft x 10 ft, and were arranged in a randomized complete block design with four replications. Individual treatments were applied at a nozzle pressure of 40 p.s.i using a CO2 pressurized boom sprayer equipped with two XR Teejet 8004 VS nozzles. All fungicides were agitated by hand and applied in the equivalent of 2 gallons of water per 1,000 ft2. Two applications were made in the fall of 2009; the early treatments were applied on 1 Oct 09, and the late treatments were applied on 29 Oct 09. Natural infection was allowed to occur, and there was continuous snow cover on the plots from mid November 2009 to mid March 2010, a total of approximately 120 days. Disease severity and turfgrass quality were visually assessed on 31 Mar 10. Data were subjected to an analysis of variance, and means were separated using Student-Newman-Keuls test (P = 0.05). Although all three major snow mold pathogens were observed, the dominant pathogen causing damage was Typhula ishikariensis. Disease pressure was high at this site with untreated controls averaging 93.3% disease. Disease pressure was so extreme that 17 of 35 treatments failed to provide significant reductions in disease severity compared to the non-treated control. Treatments containing the fungicides Interface, Triton FLO, Instrata, Concert, Tourney, QP Ipro, and QP TM/C provided significant reductions when compared to the non treated control. Of these, only the following treatments had mean disease severity ratings less than 25%; Instrata 5.5 fl oz Early/Late, Instrata 5.5 fl oz + Fore 8.0 oz, QP TM/C 6.0 oz + QP Ipro 4.0 fl oz + QP Propiconazole 2.0 fl oz, QP TM/C 6.0 oz + QP Ipro 4.0 fl oz + QP Myclobutanil 2.4 fl oz. Only QP TM/C 6.0 oz + QP Ipro 4.0 fl oz + QP Propiconazole 2.0 fl oz had an acceptable mean quality rating of 6, though several other treatments had a quality rating greater than 5. No differences in turfgrass color were observed." |
