Fusarium moniliforme was eliminated from naturally infested seeds of several corn (Zea mays) hybrids when seeds were pretreated in distilled water for 4 hr at 18–22 C and then placed in water at 60 C for 5 min. The seeds remained viable, and neither seeds nor aseptically germinated seedlings yielded F. moniliforme when plated on Komada agar medium. For seeds that were treated in distilled water at 18–22 C for 5 hr and then 55 C for 10 min, water with benomyl at 2,000 ppm for 24 hr, or acetone with benomyl at 6,250 or 25,000 ppm for 24 hr, F. moniliforme was not isolated from seed but was isolated often from aseptically germinated seedlings.
