In this paper microflora, especia11y of fungi, on the surface of apparently healthy leaves of rice plants is discussed. The second leaf from the top of variety Nakate Shin-Senbon was used for iso1ation, and many fungi, such as Candida, Rhodotorula, Penici1lium, Alternaria, Aspergi11us, and bacteria were isolated. Among them Candida sp. was most frequently isolated. The presence of Candida or other fungi in the conidia suspension of Cochliobolus miyabeanus did not disturb the conidia germination of the latter. However, if the mixed inoculation of Cochliobolus with Candida was performed to rice plants, number of the brown leaf spots decreased, representing about 50 per cent of the contro1. No microorganism, isolated from leaves of rice plants, inhibited the myce1ial growth of C. miyabeanus on agar media.
