Abstract
18 Strains of antagonistic were isolated from plant tissue of banana, which showed strong square inhibition zone in plate containing banana anthracnose spore suspension. And then antagonistic experiments in vivo of banana by artificial infection with banana anthracnose and antagonistic strains were carried out. the result showed that, compared to the control of water, only AcT-02, AcT-07, AcT-09,AcT-11, and AcT-13 could decrease banana anthracnose, with their control effect being of 49.77%±4.20%, 47.87%±8.97%, 63.82%±13.16%,68.15%±2.48% and 73.85%±2.39%, respectively. The disease index significantly discreased. The antagonistic experiment by natural infection with banana anthracnose using the five antagonistic strains showed that only the AcT-I3 fermentation can decreased the disease index of banana anthracnose and the disease index of banana anthracnose was 18.67%, being 13% lower than that of the control. Trough morphological observation, physiological and biochemical characterristics, and analysis of gene sequense, the AcT-13 was identified as Bacillus amyloliquefaciens .关键词
