Abstract/Contents: | "One experimental and several registered fungicides were applied to a Kentucky bluegrass turf area naturally infected woth red thread at the ChemLawn Research Center in Delaware, OH. The turf received minimal fertility (1.5 lbs. N per year), was maintained at 1.5 in moving height, and received 0.75 in irrigation per week. Treatments were replicated four times in 4 ft x 8 ft plots in a randomized complete block design. Fungicides were applied in 4.0 gal of water per 1000 sq ft using a CO2 powered back pack test plot sprayer with an 8020 Tee Jet nozzle. Fungicide treatments were applied as follows: a) single treatments 5 Mar; b) double treatments 5, 24 Mar; c) triple treatments 5, 24 Mar and 18 Apr; and d) double, delayed treatments 24 Mar and 18 Apr. Ratings were made on 27 May, 14 Jun and 15 Jul. Bayleton provided excellent control when two or three applications were used. Delaying the first application of Bayleton did provide slightly better control. Daconil 2787, Chipco 26019 and Rizolex provided control through the first rating period, indicating a need for additional treatments." |
