英文摘要：

Rice blast is the most harmful rice disease among the three major rice diseases,many chemicals are used to prevent this disease,which lead to drug resistance of rice blast to parts of fungicides,so the research of plant induced resistance turns up.The origin and the development,the preparation research,the developmental prospects of botanical inducer were summarized and taking Peucedanum Decursivum as example to illustrate the advances in botanical inducer induced rice blast.As an important supplementary means to control rice blast,botanical inducer has great development prospect in the future.
