| Abstract: | The culture filtrate of a strain of Bacillus subtilis is shown to be antagonistic to the growth of Rhizoctonia solani, R. bataticola, Alternaria solani, Botrytis cinerea, Fusarium udum , and Colletotrichum falcatum , exhibiting specificity of action. Malformation of the germ tube of Alternaria solani spores resulting in 'bulb' formation is also reported. Diffusion of the antibiotic principle inside host tissues is indicated. |
