Abstract:

In the present study, the fungus was isolated from infected leaf of potato and identified as Alternaria solani. Twenty four bacterial strains isolated from potato rhizosphere on PDA media. The screening of all 24 potato rhizosphere isolates for IAA, phosphate solubilization, Insecticide tolerance, salt tolerance, antibiotic sensitivity and ammonia production was performed. Out of these isolates, only four isolates (5, 15, 16 and 23) showed high inhibitory effect on the pathogenic fungus in dual culture. PGPR isolate no 5 showed highest 95% inhibition against Alternaria solani.
