Two rice cultivars infected by Gibberella fujikuroi, were tested to investigate the sequential change of disease development in the field conditions. In the preliminary test, the seeds of Nongbaek and an unknown cultivar showed 21 and $31.7\%$ infection by C. fuiikuroi. At the late stage of water nursery bed, some seedlings produced typical elongation symptom of bakanae disease and most of the leaves were dried up within a few days after transplanting. Out of the healthy looking seedlings, some plants also developed bakanae symptoms from middle June being two week after transplanting and the number was increased until middle September.
