Abstract

A substantial loss of crop production worldwide is attributed to fungal phytopathogens. The most important economic pathogens among these fungal phytopathogens are Fusarium graminearum and Rhizoctonia solani, which cause a wide range of plant diseases. In the present study, Bacillus amyloliquefaciens secondary metabolite fengycin was identified by High performance liquid chromatography (HPLC) and in vitro screened against the Fusarium graminearum and Rhizoctonia solani. Based on the HPLC result, fengycin was identified at 215nm wavelength, retention time 5-7 minutes, and peak area was 3.914. The obtained results indicated that fengycin (1, 1/2, 1/4, and 1/8) concentrations have a significant effect (p<0.005) on the growth of F. graminearum and R. solani. The current study concluded that B. amyloliquefaciens secondary metabolites fengycin having a high potential to inhibit the growth of F. graminearum and R. solani.
