Review on Biological Control of Plant Diseases

Though chemical bactericide/fungicide is an effective way to control plant disease,in chemical bacterial and fungicidal agent application there exist problems of environment pollution,ecological balance deseruction and chemical residues,and biology control attracts more and more attention.In the paper,it introduced principles of plant disease biological control,function mechanism,varieties of biocontrol bacterial,fungus,and actinomyces,and biocontrol application of plant endophytes.Besides,existing problems of biocontrol microbe in plant disease control were discussed and corresponding method proposed.
