| Abstract: | As Thanatephorus cucumerts and JK-91-b (the exudate of antibiotic bacterium 91) solution were dual spotted on PDA plate, antagonistic band with 10.7 mm in width appeared. the JK-91-b inhibited the growth of T. cucumeris, and its hyphal development became irregular and sclerotial formation was delayed. The pathogenicity of mycelia and sclerotia were reduced when treated by JK-91-b. Sheath blight seventy was reduced significantly when JK-91-b was sprayed on rice plants ahead and then untreated mycelia or sclerotia were inoculated. The control effect of JK-91-b was 45.1%. |
