A new disease called “basal node rot” of rice (Oryza sativa) characterized by retarded growth, poor tillering, dull green color of leaves, and black discoloration of the underground basal node was found to be caused by Fusarium oxysporum. The disease is common in savannas in fields where upland rice is grown in rotation with pasture grass in Brazil.
