| Research Abstract |
We obtained four non-pathogenic Fusarium spp., carrying biocontrol activity to rice Bakanae disease, from healthy rice plants' tissues. We identified two of them as Fusarium oysporum and the remaining two as F. proriferatum. Spraying the flower with these non-pathogenic isolates reduced occurrence of Bakanae disease in the plants generated from the seeds produced from the flowers. Treatment of rice with these non-pathogenic Fusarium showed no adverse effect on the growth of rice. This Bakanae disease inhibition may be due to the prevention of Bakanae fungus from entering the interior of the seed by the non-pathogenic Fusarium spp., based on the fluorescence microscopies using fluorescent protein-expressing Bakanae fungus and the non-pathogenic Fusarium spp.
