摘要
Crop disease is an important area which needs attention since most of the hazardous inputs added into the agricultural system are in the form of plant protection chemicals. 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.
