| Abstract | ||
| This study was aimed to evaluate the role of the Pseudomonas fluorescens and Aqueous extract of Cocklebur leaves in the control of the laboratory Fusarium oxysporum have been. Two isolates of P.fluorescens were isolated from Root of Cucumber Seedlings. The first one named Pseudomonas fluorescens (SH1) and the second named Pseudomonas fluorescens (SH2). The Results showed that the higher Inhibition among isolates of P. fluorescens for F. oxysporum was (100%) compared with the control treatment (0%). Also the of the experiment showed that the aqueous extract of the Cocklebur leaves has an inhibition effect on the growth of mycelium pathogen F. oxysporum on the PDA media according to the concentrations used, where the percentage of inhibition reached to 56, 66.67, 69.50 and 100%, with the concentrations of 10, 20, 30 and 40% respectively, compared to the control treatment which has 0% inhibition. In addition results showed that the aqueous extract of the Cocklebur leaves does not have inhibition of on the P.fluorescens (SH1) and P.fluorescens (SH2) by discs method where does not show any inhibition zone around the discs also in tablets soaked in sterile distilled water only. | ||
