The prevention and control effects of the growth-promotion antagonistic bacterium“98-I”on 4 Fusarium wilts

A growth-promoting antagonistic bacteria strain “98-I”against Fusarium wilt，selected from 330 strains and identified as Bacillus cereus．can effectively inhibit the soil-born Fusarium pathogens．It presents a notable efficiency in controlling 4 Fusarium wilt diseases including cucumber Fusarium wilt(Fusarium oxysporum f．sp．cucumerinum)，wa-termelon Fusarium wilt(F．O．f．sp．ni'oeum)，paprica Fusarium wilt(F．O．f．sp．Vasinfectum )，and tomato Fusarium wilt(F．0.f．sp．1ycopersici)with the corresponding spore germination inhibition rate of 79.2％，75.1％，72.3％ and 95.7％ by petri disk test．The bacterium can also promote the vegetable growth and seeds germ ination．
