In order to suppress "Akagare" disease, we tried a foliar spray of urea, potassium and manganese. The results show that spraying of urea-potassium and urea-manganese was the most effective. The plant that suppressed "Akagare" contained more amount of carbohydrate, developed many fresh root and less blackened root. Therefore we suppose that the suppression of "Akagare" by the foliar spray depends on the increase of carbohydrate content and promotion of the activity of the root.
