The aim of the present study was to identify Streptomyces spp. antagonistic to plant pathogenic fungi. From eight of different soil samples, a total of 43 isolates of Streptomyces were isolated and they were divided into 7 groups with different proportion: white 37.2 percent
grey 22.9 percent
brown 14.0 percent
yellow 11.6 percent
pink 2.3 percent
purple 2.3 percent
and blue 4.7 percent. Of 43 isolates, 16 were antagonistic to Fusarium oxysporum, 11 were antagonistic to Botryosphaeria dothidea, 3 were antagonistic to Phytophthora capsici, and 4 were antagonistic to Sclerotium hydrophylum. Two streptomyces isolates, HN6 and NA1 were selected due to their high fungal antagonism. HN6 and NA1 grew well on Gause I medium at 30°C, neutral pH and fairly high salt concentration. On ISP 9 culture medium HN6 and NA1 were able to utilize various sugar sources: D - glucose
saccarose, D - xylose, rhamnose and raffinose. The isolate HN6 was preliminarily identified as Streptomyces roseosporus, while NA1 as Streptomyces albofaciens.
