Suppressive soils hold considerable potential for managing soilborne pathogens. When the suppressiveness has a biological origin, identifying the causal organisms is the crucial step in realizing this potential. Armed with such knowledge, it may be possible to develop effective and sustainable pest management strategies through application of these organisms or agronomic practices that influence their population densities. This chapter focuses on the development and utilization of a population-based approach for identifying microorganisms involved in specific pathogen suppression. Key experimental design principles of the approach are explored by examining experiments characterizing the biological nature of take-all decline. We also describe how this approach was used to identify microorganisms that suppress the sugarbeet cyst nematode. Additional experimental design considerations and future directions for such investigations are also discussed.

鉴定涉及土壤中特定病原体抑制的微生物。

抑制性土壤具有处理土壤传播病原体的巨大潜力。当抑制作用具有生物学渊源时，确定病因生物是实现这种潜力的关键步骤。有了这些知识，就有可能通过应用影响其种群密度的这些生物或农艺实践来制定有效和可持续的有害生物管理策略。本章着重于开发和利用基于人群的方法来鉴定参与特定病原体抑制的微生物。该方法的关键实验设计原则是通过研究表征全天候下降的生物学特性的实验来探索的。我们还描述了该方法如何用于鉴定抑制甜菜孢囊线虫的微生物。
