Abstract/Contents: | "This evaluation was conducted at The Legend at Craguns Golf Club in Brainerd, MN on a creeping bentgrass 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 22 Oct 09, and the late treatments were applied on 23 Nov 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 1 Apr 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 moderate at this site with the non treated control averaging 77.5% disease. All treatments provided a significant reduction in disease severity when compared to the non treated control. Aside from Insignia 0.9 oz, all treatments provided a statistically similar level of disease control. Only 10 of the 28 treatments provided acceptable levels of disease control (<5%). Differences in turfgrass quality or color among treatments were not observed at Craguns." |
