Topdressings prepared from cornmeal-sand mixtures infested with strains of Enterobacter cloacae were used to introduce bacterial antagonists into bentgrass putting greens naturally infested with Sclerotinia homoeocarpa. Topdressings fortified with E. cloacae strains EcCT-501 and E1 significantly reduced dollar spot disease development when compared with untreated plots. In some experiments, monthly applications of strain EcCT-501 provided up to 63% disease control and was as effective as iprodione or propiconazole in reducing dollar spot severity. Disease suppression induced by strains EcCT-501 and E1 was evident up to 2 mo after application (.)
