Abstract: Biological control agents, especially Pseudomonas fluorescens, have become one of the most important and useful options for plant disease management. This study reviews the culture characteristics of P. fluorescens, including the morphological characteristics, physiological and biochemical characteristics, culture conditions and the similarities or differences with other bacteria also isolated from various plant groups to control diseases. The disease control efficiency of P. fluorescens when used alone or together with other bacteria or treatment preparations is summarized. The modes of action of both P. fluorescens and bio-active substances used for controlling plant diseases are elucidated. Hazards of P. fluorescens in medicine, agriculture and environmental protection are discussed. The outlook and prospects for biological control in the field are also evaluated and a field risk assessment presented.
