In attempt to find new organisms that have the ability to produce antibiotics for fungi biological control usage , in this study used isolated bacteria which belongs to Streptomyces spp from cultivated soil which collected from plant root region in Tobruk district , the soil samples were Dark brown and black , the soil was sandy clay loam with proximately pH 7.13- 7.29 . The physiological and morphological characterise for Streptomyces isolated samples were studied According to (Sharling & Gottlieb 1966),where isolates showed colour properties to areal mycelia and the colours were grey 40% , white 20%, yellow 20% and green 20%. The most of isolates showed inability to produce soluble pigment, the isolates were tested to show the ability to produce antifungals to prevent the growth of unicellular fungi and filament fungi as Candida, Rhizopus, Mucor, Phoma, Aspergillus, and Trichoderma. The results showed the ability of Streptomyces isolates to produce anti- material against tested fungi samples which used in this study.
