The overall results of this study show that isolates of
T. harzianum,T. asperellumand T.flavushave significant antagonistic
effects on R. solani, a pathogenic fungus causing seed rot and
damping-off diseases on sugar beet. The results also indicate that
mixing the above-mentioned fungal antagonists with organic and
inorganic carriers preserved their antagonistic potential for controlling R. solani-induced sugar beet seedling damping-off disease
