Action of Bacillus SPP Endophytes of Chenopodium Ambrosioides L on the Fusarium solani, Botrytis cinerea and Aspergillus niger
Thirty one bacterial strains were isolated from root tissues, stems and leaves of Chenopodium ambrosioides L. The antifungal activity of these bacterial strains were tested in vitro by the technique of dual culture against Botrytis cinerea fungi; agent of gray rot on grapes, Fusarium solani; causal agent of Fusarium wilt of pepper and Aspergillus niger; causative agent of crown rot of peanuts. Four bacterial strains BR1, GT1, GR1 and GR2 induced inhibition of mycelial growth of Botrytis cinerea, Fusarium solani and Aspergillus niger with a rate greater than or equal 52%. These four strains are Gram positive bacilli, aerobic strict and capable of forming endospores. They belong to the family of Bacillaceae.
