Abstract

1. Fusarium tuberivorum Wilcox and Link is the same as Fusarium trichothecioides Woll. 2. Both Fusarium oxysporum and F. trichothecioides can produce both tuber rot and wilt of the potato plant. 3. The wilt is induced by destruction of the root system and by clogging of the xylem elements in the stem, and is, in mild cases, marked by such symptoms as discoloration of leaves, curling and rolling of leaves, and production of aerial tubers. 4. Under field and storage conditions Fusarium oxysporum is more probably responsible for wilt than is F. trichothecioides, and the latter more responsible for tuber rotting .
