Abstract: Actinomycetes are one of the most attractive sources of antibiotics. In the present studies, total of 11 Actinomycetes strains were isolated from the Noida, U.P. India. Isolated strains were identified for their antifungal activity these isolates showed good result, they were evaluated for their inhibitory activity on 4 strains of pathogenic microorganism such as (Asp. niger, Alternaria alternata, Alternaria solani & Alternaria pori). Isolation of Actinomycetes strain was obtained by Serial dilution method and grown on actinomycetes isolation agar. Antifungal compounds were checked against fungal culture. The culture characteristics of isolates were also studies in different culture media. The results indicated that 11 Actinomycetes isolates were highly active against Alternaria pori and Aspergillus niger, Alternaria alternate, Alternaria solani strains. Out of 11 Actinomycetes isolates 5 isolates showed a inhibition higher than 50% for the above mentioned plant pathogenic fungi. Thus, these isolates could be developed into formulations for non toxic, non chemical fungicide for use on crops.
