Production of the crop is, however, constrained by several disease infections including fungal diseases. The present study focused to isolate, Pseudomonasfluorescens possess a variety of promising properties which make it a better biocontrol agent. Two Pseudomonas fluorescens isolates from rhizospheric soil of faba bean were evaluated for their antagonistic activity against Botrytisfabae that is known to attack faba bean crops. Bio-primed faba bean seed with P f 9 and P f 10 （Pseudomonasfluorescens isolates 9 and Pseudomonasfluorescens isolates 10） for pathogencity test in green house was indicated an initiate positive result respectively. Two isolates of P f 9 and P f 10 reduced both disease severity and incidence. So it could be concluded that the used P f9 and P f 10 could resist the detrimental effects of Botrytisfabae on the plant growth and yield that will be used as biocontrol in the farm after field test.展开更多
