Abstract
Foliar applications of sterol demethylation inhibiting fungicides were evaluated for control of ergot (Claviceps purpurea) in a Kentucky bluegrass (Poa pratensis) seed production field near Post Falls, Idaho, during 1990 and 1991. Flusilazole, propiconazole, tebuconazole, and triadimefon were applied at several rates and plant growth stages. Single applications of all fungicides except triadimefon significantly reduced ergot compared with nontreated controls. Sclerotia and panicle exudate (honeydew) were reduced to zero, or near zero, with single applications of flusilazole alone or with flusilazole, propiconazole, and tebuconazole combined with a wetting agent
