| Abstract/Contents: | "Trials were conducted at Veenker Golf Course on the campus of Iowa State University, Ames, IA. Fungicides were applied to creeping bentgrass maintained at 5/32-inch cutting height, using a modified bicycle sprayer at 30 psi and a dilution rate of 5 gal/1000 ft². The experimental design was a randomized complete block with four replications. All plots measured 4 ft x 5 ft. All plots were surrounded by 1-ft-wide strips of untreated turf in order to help create uniform disease pressure. Fungicide applications began on 9 Jun and were repeated at recommended intervals on 16, 23, and 30 Jun and 7, 14, and 21 Jul. Jun and Jul had approximately normal rainfall and temperature, but mid-Jul was somewhat cooler and drier than average. Disease development on the untreated check plots was moderate to severe on all rating dates. Most formulations suppressed disease significantly on each rating date. Several treatments provided excellent control on all rating dates; two treatments, Thalonil 4 L at 6.0 oz and 7-day interval, and EXP 10452A at 2.0 oz and 14 days, showed no disease on any rating date. Treatments that exhibited an enhanced green color on one or more rating dates included Sentinel 40 WG at a 28-day interval, Eagle 40 W, EXP 10452A at both rates, and Banner plus ProStar at 1- and 2-oz rates, respectively, and a 28-day interval." |
