Biological control is a non-hazardous technique to control plant diseases. Researchers have explored microorganisms that show high plant-disease control efficiency for use as biological control agents.
A single soil application of Bacillus amyloliquefaciens strain S13-3 suppressed tomato bacterial wilt caused by Ralstonia solanacearum, a soilborne bacterial pathogen, through production of antibiotics augmented possibly by induction of systemic acquired resistance. Soil application also controlled tomato powdery mildew disease through induction of systemic acquired resistance.
S13-3 showing bifunctional activity with a single application to soil may be an innovative biological control agent against bacterial wilt and powdery mildew in tomato.
生物防治是一种控制植物病害的无害技术。研究人员已探索出对植物病害具有高效防治效果的微生物，用作生物防治剂。
单一土壤施用解淀粉芽孢杆菌菌株S13-3可抑制由青枯雷尔氏菌引起的番茄青枯病，青枯雷尔氏菌是一种土壤传播的细菌病原体，其通过产生抗生素（可能通过诱导系统获得性抗性增强）来实现。土壤施用还通过诱导系统获得性抗性来控制番茄白粉病。
单次施用于土壤即表现出双功能活性的S13-3可能是一种防治番茄青枯病和白粉病的创新型生物防治剂。
