ABSTRACT
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.
