Abstract
This paper reports “Ear-blight”, a nematode disease of Italian-millet (Setaria italica). The symptoms were found to be identical with the description given by NAKANO, who reported that the parasite probably belonged to Tylenchus (Anguillulina). With their studies on the morphology of the pathogenic nematode, the writers came to the conclusion that the pathogen is identical with Aphelenchoides oryzae YOKOO, the causal organism of white-tip of rice.
