用含炭疽病菌的ＰＤＡＹ平板上分离香蕉组织表面的拮抗菌株，经离体和活体测定对香蕉炭疽病的防效，筛选到９６００３、９６１２０、９６２０６、９５０４０、９６２０１、９５０１９、９５０４２及９６００４等８个有显著拮抗作用的菌株，其中９５０１９是酵母菌，其它为细菌．９６００３防效最佳，达６７％．供试菌株的拮抗作用机制可分为抑菌和竞争两类．
Antagonistic strains of banana tissue were isolated from PDAY plates containing anthracnose bacteria, and the control effect on banana anthracnose was tested in vitro and in vivo. Eight strains of 96003,96120,96206,95040,96201,95019,95042 and 96004 There are significant antagonistic strains, of which 95019 is yeast, the other bacteria. 96003 best effect, up to 67%. The antagonistic mechanism of the test strains can be divided into two categories of antimicrobial and competition.
