Employ metabolic capabilities of Pseudomonas in bio-control

Abstract

samples collected from different environmental sources included soils contaminated and 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.
