to study of biological control of charcoal rot of melon caused by macrophomina phaseolina, 187 isolates of fluorescens pseudomonas isolated of rhizosphere and soil of melon plants. then 12 isolates belong to i, iii and v biovars of p. fluorescens and b biovar of p. putida were selected for greenhouse experiments based on inhibition amount. pseudomonas isolates inhibited mycelial growth signific...

A potential antagonist, designated strain Bacillus subtilis MBCU5 was previously isolated from vermicompost-amended soils of Gandhinagar, Gujarat, India. Crude allelochemicals from strain MBCU5 displayed strong antifungal activity against Macrophomina phaseolina as well as Rhizoctonia solani. These crude allelochemicals were tentatively identified as iturin, fengycin and surfactin through TLC a...
