| Abstract: | Biologic control efficacy of endophytic bacteria G10 against the seedlings damping-off incited by Rhizoctonia solani of sesame was evaluated in green house conditions and field tests.The results showed that G10 could control the harm of Rhizoctonia solani efficiently and the control efficacy were 81%～89% in pots tests and 61% in field tests.Then experiment was carried out to test the characteristics of the strain G10.Abilities to produce chitosanase and prolease of G10 were assayed on culture plates with colloidal chitosan and milk,which revealed that the strain G10 could produce chitosanase and prolease respectively.By physiological characteristics and the morphology identification the strain G10 belongs to Bacillus subtilis. |
