The organic phase of a wide spectrum, antimycotic and diffusable toxin from Erwinia herbicola showed a highly significant inhibitory activity against Pyricularia oryzae spores in spore well bioassay. Germ tube lengths were inhibited more in wells containing 5 microliters equivalent of bacterial toxin than 1 microliter. No significant difference between the germ tube in an equal mixture of Dimethyl sulphoxide: ethanol and controls. Thin layer chromatography using the chloroform extraction of the organic phase showed a significant antagonism on Cladosporium cucumerinum. The retardation factor values for inhibitory zones in solvent 1 were 0.07 for lower spot and 0.26 for upper spot.
来自草生欧文氏菌的一种广谱、抗真菌且可扩散毒素的有机相，在孢子孔生物测定中对稻瘟病菌孢子表现出高度显著的抑制活性。在含有5微升等效细菌毒素的孔中，芽管长度的抑制比1微升时更明显。二甲基亚砜与乙醇的等量混合物中的芽管与对照之间无显著差异。使用有机相氯仿提取物进行的薄层色谱显示对黄瓜枝孢有显著拮抗作用。溶剂1中抑制区的比移值，下方斑点为0.07，上方斑点为0.26。
