samples collected from different environmental sources included soils contaminated and Sixty
non-contaminated vehicles hydrocarbon and water drainage and sources of clinical from Diwaniyah
Educational Hospital, for the period from January 28/ 2013 until February 1/ 2014. Sixteen isolates
were obtained Pseudomonas aeruginosa and 6 isolates belonging Pseudomonas fluorescens, and were
selected from P. aerugionsa and isolate of P.fluorescens for the purpose of testing their ability
metabolite in biological control fungi direction F.solani and A.alternata isolated from infected tomato
plants with these fungi and collected samples from greenhouses in Diwaniyha. The results showed
that all the bacteria isolates were stimulating plant growth, as are all influenced the increase in plant
height and root length and dry weight increase and soft grouped to shoot and root and significant
difference (P <0.05) for seed treatment fungal pathogens only. Showed P. aerugionsa isolated from
urinary tract infections at P.fluorescens and isolated from soils contaminated by hydrocarbon
compounds of high ability to protect tomato plants from fungal infection Pathogenetic.
