Abstract/Contents:"Bentgrass dead spot (BDS), incited by the fungus Ophiosphaerella agrostis, is a new disease of creeping bentgrass greens and tees. Fungicides were evaluated for their ability to control BDS on a naturally infested golf course green. Fungicides representing ten different chemical classes were applied at various rates and intervals. Data were collected for disease severity, turf quality, and algal cover. Fungicides within the benzimidazole, dithiocarbamete, nitrile, phenylpyrrole, and phosphonate classes provided the most effective control of BDS (78-97% control, compared to untreated turf). Of the sterol-inhibiting fungicides, only propiconazole adequately controlled BDS (95% control), whereas myclobutanil and triadimefon proved ineffective at the rates tested. Similarly, two experimental strobilurin fungicides (BAS 500 and 505) consistently suppressed BDS (96-97% control), while strobilurins triflozystrobin and azoxystrobin provided poor to fair control (3 and 72% control, respectively) of BDS. Carboximide and phenylamide fungicides, and a strain of Bacillus subtilis, did not significantly control BDS."
