Abstract/Contents:"An initial study showed that more antagonistic bacteria were isolated from lowland paddy field with less incidence of sheath blight. Seed bacterization with bacteria from healthy and from rhizosphere soil of healthy plants provided 76% sheath blight protection, whereas little protection was given by bacteria from infected samples. Soil samples from disease-free fields appeared to be more supressive to R. solani . Rhizosphere soil samples were then collected from six locations in the Philippines and were assayed for suppressivness to R. solani. Forty-five percent of 104 samples were suppressive to R. solani. The linear mycelial growth of the pathogen was 50% less in suppressive than conducive soils. Given the same inoculum density in pot experiments, sheath blight severity was less suppressive than in conducive soils. The inhibitory effect was removed by sterilization but could not be restored in a mixture with 20% suppressive soil."
