Antifungal activity of Streptomyces spp. isolated from rhizosphere of Thai medicinal plants
A collection of Streptomyces isolates from the rhizosphere of sixteen medicinal plants was assessed for in vitro antagonistic activity against six plant pathogenic fungi; Alternaria brassicicola, A. porri, Colletotrichum gloeosporioides, Fusarium oxysporum, Penicillium digitatum and Sclerotium rolfs...
