Screening of Actinomycetes against Fusarium oxysporum

The authors treated different soil samples by different temperatures,spore activation reagents and inhibitors,culture mediums and obtained 69 actinomycetes strains against Fusarium oxysporum.The optimal screening method was as the followings: soil samples treated by 100℃dried hot for 1h,then diluted with 0.05% SDS;the favorable media are Gause No.1 including 1μg/ml penicillin,starch agar or HVG respectively,culture temperature was 28℃ for 7d.
