Green biological method for preventing and treating root rot disease of maize

The invention discloses a green biological method for preventing and treating a root rot disease of maize, and belongs to the technical field of biological prevention and treatment of plant diseases. According to the method, maize resistance is induced by means of an inactivated pathogenic fungus rhizoctonia solani inducing liquid, and therefore the purpose of preventing and treating the root rot disease of the maize is achieved. The method is characterized in that the inactivated rhizoctonia solani inducing liquid is utilized for biologically preventing and treating the root rot disease of the maize; the inducing liquid is inoculated onto stalk wounds of the maize or directly applied to the portions surrounding roots of small maize seedlings, and therefore the maize resistance is improved. The green biological method for preventing and treating the root rot disease of the maize is good in effect, free of secondary pollution and residues and low in cost. 本发明公开了种绿色的防治玉米根腐病的生物方法，属于生物防治植物病害技术领域。该方法通过利用灭活的病原真菌立枯丝
