Abstract/Contents:"This experiment was conducted on an established bentgrass plot at the Turfgrass Research Center, NCSU, Raleigh, NC where bentgrass had been previously infected with S. homoeocarpa. Disease pressure of dollar spot was severe in 1986. The soil type was a Cecil Gravely Sandy Loam. all treatments were arranged in a randomized comprete block design with four replications and applied twice with carbon dioxide backpack sprayer using the equivalent of 2.5 gal of water per 1000 ft. The first application was made on 2 Jul and the second on 12 Aug. Plots were 5 x 5 ft. The summer was hot and dry. Plots were watreed as needed. Percent disease was rated approximately every 2 weeks. A table showing the rate of infection of brown patch and dollar spot to the treatments and rates of fungicides is included. Disease pressure from dollar spot at the time of the first application was light. Brown patch developed approximately 3 weeks after the first application. All fungicides gave acceptable control of dollar spot except Daconil 2787. Only Daconil 2787 and HWG 1608 applied on 26 Aug provided brown patch control significantly better than the nonsprayed control. No phytotoxicity was observed."
