This study was carried out for the purpose of detection and compatibility of Pseudomonas fluorescence and fungicides to control Fusarium graminearum, Fusarium moniliforme and Fusarium poliferatum .The pathogenicity in filter blotter test indicated that the seed decay symptoms were reduce from corn seeds to 52 for the fungus Fusarium graminearum , 55 for Fusarium moniliforme and Fusarium poliferatum 4.5 × 10 6 was the lowest concentration showed inhibition of fungi growth of 77.5, 77.5, 85% sequentially. No toxic effects of chemical pesticides were recorded on the growth of P.f bacteria when mean concentration were used, the results showed a high degree of compatibility of Pseudomonas fluoresces bacteria with half effective concentration of chemical pesticides to suppressing pathogenic fungi, as well as an increase in plant growth parameters.
