Abstract/Contents:"Evaluations of fungicides for control of brown patch in creeping bentgrass, 1997. Trials were conducted at Veenker Golf Course on the campus of Iowa State University, Ames, IA. Fungicides were applied to creeping bentgrass (cv unknown) maintained at 5/32-in cutting height, using a modified bicycle sprayer with flat fan nozzles at 30 psi and a dilution rate of 5 gal/1000 ft^D2. The experimental design was a randomized complete block with three replications. All plots measured 4 ft x 5 ft. All plots had 1-ft-wide strips of untreated grass on opposite sides to help create uniform disease pressure. Fungicide applications began on 11 Jun; subsequent applications were made at recommended intervals on 18 and 25 Jun and 2, 9, 16, 23, and 30 Jul. Brown patch symptoms were first observed on 1 Jul. Disease development was moderately severe on 4, 10, and 24 Jul and severe on 18 Jul. Many, but not all, fungicide treatments exhibited [significantly] (LSD, Pā‰¤ 0.05) less disease than the untreated check. No phytotoxicity symptoms were observed."
