Abstract/Contents:"'Penncross' creeping bentgrass (Agrostis palustris Huds.) field plots were used to determine efficacy of chemical and biological treatments for controlling Rhizoctonia blight. Treatments were initiated on 25 September 1990, and the study continued with varying frequencies of treatment application during a 6-week period on intensely watered and fertilized field plots. Rhizoctonia inoculations were made on turfgrass plugs removed from treated field plots 4 and 5 weeks after initiating the study. Rhizoctonia foliar blighting on recovered field plugs was less on Daconil 2787 4F and Daconil/ASC treated field samples than on Terraguard 50W or experimental biological treatments tested. Of experimental biological treatments used in the study, ASC66889-1 and -2, ASC66912-1 and Soil Inoculant I (2.6 kg) gave some disease protection on the 4 week old field plugs. None of the biological treatments gave disease suppression on the 5-week samples. Chemical disease control products generally were superior to biological treatments."
