Eleven bacterial isolates were isolated from wet rice field in Wates, Kulon Progo. The result of antagonism test on nutrient agar (NA) showed that only two isolates (WKP-4 and WKP-6) were antagonistic to Rhizoctonia solani. Determination on these two isolates showed that they were belong to the group of fluorescent pseudomonads. In the glass house trial, only WKP-6 suppressed the relative lesion height of sheath blight of rice variety IR 50.
