Abstract/Contents:Presents a study conducted to examine potential benefits of "the preventative approach to dollar spot." Explains that preventative application is "designed to suppress the barely active turf pathogen before it can infect host tissue." Suggests that "by reducing the initial population of pathogen in the thatch and soil the symptoms of dollar spot infection will be delayed until after in the summer or the disease severity that is observed is lower than normal. The delay increases the time between fungicide applications, saves superintendents money, and reduces the use of chemicals." Details methods and materials used in the study, stating that "the individual plots of the study measured 3 x 5 ft [feet] and were arranged in a randomized complete block design with four replications. All study locations received all 26 treatments on May 2nd, 2005...Fungicide treatments were applied at a rate of 2 gallons per 1000 ft2 [square feet] using a CO2 pressurized boom sprayer equipped with XR Teejet 8005 VS." Reports that "due to the abnormally cool spring and then a hot, dry summer, disease pressure did not appear until much later than anticipated...Through June and July Madison and Milwaukee [Wisconsin] rarely fell below 80°F [Fahrenheit], and into the favorable range of temperatures for dollar spot activity...The synergistic combination of Banner Maxx and Bayleton (treatment #26) did not work for this particular study. Interestingly, three fungicides, Curalan (1 oz [ounce]/1000 ft2), Turfcide 400 (3 fl [fluid] oz/1000 ft2), and Eagle (2.4 fl oz/1000 ft2) showed exceptional control (less than 10% damage) against dollar spot." Concludes that "the abnormal weather conditions reduced the overall disease pressure. Despite the lack of cooperation from the weather, the data from the preventative study still adds to the growing rationale behind early preventative applications...Further studies will be needed to further investigate the practicality and efficacy of preventative fungicide applications."
