Both fermentation broth and solid state fermentation of Streptomyces roseoflavus Men-myco-93-63 isolate were used for controlling tomato and cucumber root-knot nematode. The control efficacy and its effect on soil microbiota were studied. The results showed that the control efficacy of the treatment on cucumber and tomato by 1 V∶200 V solid state fermentation of Men-myco-93-63 were 65.62% and 57.69%,respectively. The application of bio-agents has increased the number of bacteria and actinomyces in soil by 19.57% and 316.67%, respectively,while the number of fungi reduced by 28.57%. The three kinds of the cultivable soil microorganism raised from 7.40×106 cfu·g-1 to 16.75×106 cfu·g-1,amount to 126.35%.
