"Experimental plots of Agrostis stolonifera subsp. palustris were established, received conventional care with minimum nitrogen fertilization, and were maintained at a 0.25" cutting height. Most treatments were applied at 25 psi with a backpack sprayer equipped with a 6 ft boom having 4 nozzles and delivering 2 gal/1000 ft2. Bayleton 0.5G was distributed by hand. Treatments were applied to 6X5' plots replicated 5 times. Except as noted (in table), plots were treated biweekly from 16 May to 15 Aug. GX-077-A 40% ws not applied until 13 June. Plots were evaluated 22 June and 23 Aug by # infection centers/plot." An included table shows that no disease was observed at the start of the test, but symptoms of Lanzia, Moellerodiscus became very evident as the season progressed. All treatments except GX-077-A gave significant disease control, with Bayleton 25 DF and all Banner treatments providing the best control. No phytotoxicity was observed.
