粘质沙雷氏菌菌株 B2 抑制水稻纹枯病病原体立枯丝核菌 AG-1 IA 的菌丝生长。用细菌悬浮液处理水稻植物，然后用病原体接种攻击。粘质沙雷氏菌的施用有效降低了纹枯病的发生率。 S. marcescens 在温室条件下的土壤中存活。施药后 4 周内，10(8) 菌落形成单位 g(-1) 土壤。这些结果表明，粘质沙雷菌有潜力作为水稻纹枯病的有效且持久的生物防治剂。
Serratia marcescens strain B2 inhibited mycelial growth of the rice sheath blight pathogen Rhizoctonia solani AG-1 IA. Rice plants were treated with bacterial suspension and then challenge inoculated with the pathogen. Application of S. marcescens effectively reduced the incidence of sheath blight. S. marcescens survived in soil under glasshouse conditions at ca. 10(8) colony forming units g(-1) of soil for 4 weeks after application. These results suggest that S. marcescens has potential as an effective and persistent biological control agent for rice sheath blight.
