Management of Fusarium Head Blight of Wheat and Deoxynivalenol Accumulation Using Antagonistic Microorganisms

Abstract

Infection rate of chestnut tree by Botryosphaeria(Dothiorella) dathidea was about at Gapyung area. disease symptom of chestnut did not appear in October but appeared in November, showing in May in ext year. B. dothidea was more pathogenic to chestnut than did Catinula sp. and Fusicoccum sp. B. dothidea uses soft rot, but Catinula sp. and Fusicoccum sp. causes dry rot. Mycelial growth of B. dothidea was optimal at . Mycelial growth was stimulated when water potential decreased from -2 bars to -12 bars and declined from -12 bars to -60 bars.
