Potato scab is the main disease affecting the development of the potato industry, which is caused by a variety of Streptomyces (Steptomyces spp.) The purpose of this study was to screen the strains with high antagonistic effect on potato scab bacteria, and to study the control effect and mechanism of antagonistic bacteria through experiments, so as to provide strain resources for the development of biocontrol fungi, and at the same time, it can effectively promote the development of biological control technology for potato scab disease, which has a good application prospect.
