Abstract
馬鈴薯瘡痂病為嚴重影響馬鈴薯產量與品質之重要病害之一，目前並無有效之防治藥劑可用，而輪作及抗病品種等耕作防治法效果亦有限。因此，本研究自高雄不同地區之土壤分離純化85 株放線菌後，以玻璃紙抗生法於培養基上初步篩選對馬鈴薯瘡痂病菌Streptomyces europaeiscabiei 具有拮抗活性之菌株，再利用拮抗菌株之培養濾液進一步測試其拮抗活性。Potato common scab is an economically important disease that is caused by several members of the genus Streptomyces in the world. As no effective pesticides and limited results of crop rotation and resistant potato cultivars for managing the disease, this study explored the possibility of using biological control. A total of 85 isolates of actinobacteria were isolated from soil from six different locations in Kaohsiung City. Cellophane paper antibiotic method and bacterial culture filtrates application were conducted to determine antagonistic activity against Streptomyces europaeiscabiei. Isolates 35-2 and 43-21 strongly inhibited S. europaeiscabiei growth in both assays.
