30 minutes. Treated seeds were planted in soil inoculated
with F. oxysporum. Seeds planted in Fusarium-inoculated
soil were succeptible to Fusarium wilt showed by IFF. On
the other hand, Fusarium wilt of seedling was suppressed
by soaking the seeds into the isolate solution prior planted.
However, the isolate ability to control the disease was
varied (Figure 1). BK08 decreased more damping-off rather
than others. Seedling dumping off with BK08 treatment
was only 17.86%, while percentage of damping off in
untreated seeds was relatively high. At the end of study,
82.14% of IFF seedling was damp off. In accordance with
its suppression to damping off, BK08 relatively reduced
damping off by 60.71% (Figure 2).
One out of thirty seeds did not grow, and one out of
growing seedling of IFFF died at the end of study. It is
believed that it was not because of Fusarium wilt, but it
was their viability. Fusarium wilt was observed after
13 days of seedling in IFF, and between 14-17 days of
seedling in the treated seeds. The numbers of seedling
damping-off were increased rapidly to 4 weeks of
observation. Our observation also showed that late
seedlings were observed in the treatments in which the
pathogen may take its role.
