| Abstract/Contents: | "The experiment was conducted at the White Manor Country Club, Malvern, PA, on an 'L-93' creeping bentgrass fairway maintained at 0.425-in. situated on a Wehadkee silt loam soil. Treatment plots, 3 ft x 6 ft, were arranged in a randomized complete block design with three replications. Treatments were applied with a CO 2-powered sprayer, using a TeeJet 11008E nozzle at 40 psi, in water equivalent to 2 gal per 1000 sq ft. Applications were made on a 14-day interval on 29 Jun, 13 and 29 Jul. Disease severity (index 0 to 10; 0=turf asymptomatic; 10=>90% turf area symptomatic) was assessed on 29 Jul and 5 Aug. Data were subjected to analysis of variance and multiple comparisons of the mean values were made using the Waller-Duncan k-ratio test (P<=0.05). Environmental conditions were highly conducive for brown patch development early in July in southeastern Pennsylvania. Brown patch pressure was moderately high throughout the study. Several registered fungicides including, Insignia, Torque, Disarm M, Honor, Prostar, Daconil Ultrex, and Endorse provided good control. Two non-fungicide products, DewCure and BioGold, were included in the trial. DewCure is a product that was designed to decrease excess leaf moisture, and it showed significant suppression of the disease when compared to the untreated control. BioGold is a soil inoculant that contains a variety of aerobic and anaerobic microorganisms which aid in the uptake of nitrogen for increased plant health. However, BioGold did not exhibit disease suppression. No phytotoxicity was observed in any of the treatment plots during the course of the experiment." |
