Abstract/Contents:"Rapid seed germination and seedling development of rough bluegrass (Poa trivialis L.), also called roughstalk or roughstalk bluegrass, are critical to establishing a quality putting surface on overseeded bermudagrass (Cynodon spp.). Fungicides are applied at seeding to protect seedlings from pathogens, however, some fungicides may hinder germination and seedling development. We conducted growth chamber and field studies to identify fungicides that adversely affect germination and seedling development of rough bluegrass. Fosetyl-Al and mancozeb eliminated germination in vitro. Triadimefon and fenarimol reduced germination and stunted seedlings. Cyproconazole stunted seedlings, but did not affect germination. Damaging fungicide concentrations were between 10.0 and 76.0% of initial tank concentrations. The effects of these fungicides were eliminated in vitro by rinsing seeds with water, even after 24 h of contact with the fungicides. In field studies, only fenarimol and cyproconazole reduced seedling establishment. Fungicide effects on recently established rough bluegrass differed by study and cultivar. In one field study, mancozeb, chlorothalonil WS, chlorothalonil Zn, and azoxystrobin increased turf quality of `Cypress', but decreased that of `Winterplay'. In another study, these fungicides had little effect on either cultivar, but mefanoxam enhanced turf quality of both cultivars. We conclude that fenarimol and cyproconazole should not be used when seeding rough bluegrass. Fosetyl-Al, triadimefon, and mancozeb may also inhibit establishment. Iprodione, chlorothalonil WS, chlorothalonil Zn, mefanoxam, and azoxystrobin can be used at establishment with no negative effects on rough bluegrass germination and seedling development."
