Abstract/Contents:"Bentgrass turf was maintained at a height of 11/64 in. and irrigated with 0.3 in. water three times a week. Plots were not fertilized during the growing season. Fungicides were applied at a rate of 5 gal solution per 1000 sq ft using a carbon dioxide backpack sprayer at 25 psi equipped with a Tee-jet 8003 flat fan nozzle. Treatment dates were 11 Jun and 2 Sep with disease and phytotoxicity ratings taken on 8 Jul and 28 Sep. Plots were 5 ft x 5 ft with five replicated treatments arranged in a randomized complete block design. Rainfall from May through Sep was near normal, and temperatures were above normal for May, Jun, and Jul and slightly below normal for Aug and Sep. Due to hot weather disease severity was lot from May through July, But with cooler temperatures in Aug and Sep disease severity reached a moderate level. Aliette and Spotless effectively controlled yellow tuft; however, Spotless caused moderately severe phytotoxic injury to the turf. RH-3486 was not effective against yellow tuft and at the 6 oz rate was moderately phytotoxic."
