| Abstract | ||
| This research include isolation and identification of F.solani which is the offshoots death in refaai region / Thi-Qar province. Also the ability of pathogenicity of causative agent determined in perform of disease and estimation of efficacy of biological control agents Trichodr, P. fluorescens and Opera pesticide in inhibition of F.solani growth In vivo and protection of seeds and offshoots of plam. The research shows Antagonist between T.viride and F.solani in the ability of biological fungus in the inhibition of pathological fungus. The ratio of bacterial inhibition was 71% and the optimal temperature to F.solani growth was 25º C, the optimal pH was (5-8). In the condition of lathehouse appeared that all treatments decreased significantly in ratio of infection virulence and high increase significant in long of root and vegetative P. fluorescens and Opera pesticide was more efficient among all treatments against F.solani the infection virulence ratio and long of root and vegetative was 13.30 , 33.33, 27.33 cm consequently. | ||
