Abstract: 

Chemical measures are losing their attractiveness because of development of resistance in pathogens and undesirable effects on environment. Control of pathogens with natural product derivatives has gained great importance worldwide. Actinomycetes inhibit pathogens via production of biologically active secondary-metabolites. Actinomycetes are diverse taxon with diverse ability in prokaryotes. They are sources of antibiotics and other biologically active substances of high commercial value.
In order to obtain antifungal antagonists from soil Actinomycetes, a vast survey was performed. Over 100 isolates were isolated and some of them showed high level of activity in Agar disk against Rhizoctonia solani. The active strain was propagated in submerged cultures and active crude was prepared upon which several biological characterizations performed.
