Abstract

Two endophytic bacteria strains named as LJ and XM with strong antagonism against Phytophthora capsici were isolated from eleven different healthy plants.Both strain LJ and XM could suppress many plant pathogenic fungi.The fermentation filtrate of LJ and XM showed strong antagonistic activities to the zoosporangium formation and zoospore germination of Phytophthora capsici.The hypha of Phytophthora capsici treated with fermentation filtrate of LJ and XM showed different degrees of protoplast concentration.
