| Abstract: | Bacillus subtilis B_(2-47) was isolated from the soil in the rhizosphere of Wheat.The inhibitory action to pathogenic fungi of Gaeumannomyces graminis var tritici strain 9826 and 9812 was 61 % and 56 % respectively.The control efficacy with B_(2-47) against the disease of the wheat Take-all in pot tests was 63 % and 64 % respectively,better than that of commonly used chemical fungicide,which is 56 % and 54 %.The antifungal mechanism was mainly deformation of the cell of hypha and disintegration of the cell wall. |
