To solve this issue, our first-year project has isolated several biological control microorganisms and tried to develop potential chemical or fertilizer control methods. For our second-year project, we propose to analyze the antimicrobial compounds secreted from biological control agents, and from which we plan to develop chemical therapeutic strategy. In addition, we surprisingly found that tebuconazole, a traditional fungicide, can inhibit S. scabies, and plan to test its therapeutic efficacy through pot assays. Meanwhile, we propose to conduct field experiments in 2016 in order to identify an effective biocontrol agent for farmers’ use.馬鈴薯瘡痂病生物防治Potato common scabBiological control
