The use of microorganisms and their secreted molecules to prevent plant diseases is considered an attractive alternative and way to supplement synthetic fungicides for the management of plant diseases. Strain BS062 was selected based on its ability to inhibit the mycelial growth of Botrytis cinerea, a major causal fungus of postharvest root rot of ginseng and strawberry gray mold disease. Strain BS062 was found to be closely related to Streptomyces hygroscopicus (99% similarity) on the basis of 16S ribosomal DNA sequence analysis. Postharvest root rot of ginseng and strawberry gray mold disease caused by B. cinerea were controlled up to 73.9% and 58%, respectively, upon treatment with culture broth of Streptomyces sp. BS062. These results suggest that strain BS062 may be a potential agent for controlling ginseng postharvest root rot and strawberry gray mold disease.
利用微生物及其分泌的分子来预防植物病害被认为是一种有吸引力的替代方法，也是补充合成杀菌剂以管理植物病害的途径。菌株BS062是基于其抑制灰葡萄孢菌菌丝生长的能力而被挑选出来的，灰葡萄孢菌是人参采后根腐病和草莓灰霉病的主要致病真菌。基于16S核糖体DNA序列分析，发现菌株BS062与吸水链霉菌密切相关（相似度99%）。用链霉菌属BS062的培养液处理后，人参采后根腐病和由灰葡萄孢菌引起的草莓灰霉病的防治率分别高达73.9%和58%。这些结果表明，菌株BS062可能是控制人参采后根腐病和草莓灰霉病的潜在药剂。
