Abstract/Contents:Plots were located on a Manhattan ryegrass turf established September 1985 at the University of Nebraska John Seaton Anderson Turfgrass Research Facility, Mead, NE. Brown patch developed rapidly during the growing season and had reached moderately severe levels by mid-July. When evaluated at the time of the last fungicide treatment on August 4, brown patch severity was significantly less for all treatments compared to the untreated check. Daconil 2787 Flowable, Bayleton, Broadway and ASC-66518 were continuing to hold the disease at low levels 3 weeks following the final applications. There were no differences in disease severity between Daconil 2787 Flowable applied weekly at 3 fl oz or biweekly at 6 fl oz. The same trend was noted in the application interval of ASC-66825. The included chart provides the brown patch severity and application schedule from 10 July- 10 August.
