Abstract

The current study including two parts .The first part was determination of the antagonistic activity to biobesticide floramil against Pythium aphanidermatum for fevabeen seedling. The second part was identify the biofungicides properties to this biofungicides in order to improve growth .The results revaled that floramil have high inhibition ability of P.aphanidermatum growth on P.D.A.medium by (100%).In addition to that ,floramil have efficiency for protect feva beens from P.aphanidermatum infection by rising of germination percentage to (90.2)of the treated seeds in polluted soil by Pythium infections ,However the control was (0).It was noted that number of Pseudomonas fluorescence between in aroot area of plant .treated with biobesticide reaching to 2.5×10 7 colony unit / gm when it present with infected fungi .However ,it decrease to 0.33×106 colony unit / gm in the absent of infected fungi.
