Biological control has been considered a sustainable alternative to combat phytopathogens. The increase of studies in the past few years involving Actinobacteria as biological control agents of phytopathogenic fungi has motivated us to search for which Actinobacteria genus that have been studied in the last five years and explore their mechanisms of antifungal activity. The accesses were carried out on three multidisciplinary digital platforms: PubMED/MedLine, Web of Science and Scopus. Actinobacteria from genus , , , , , , and especially showed a broad antifungal spectrum through several antibiosis mechanisms such as the production of natural antifungal compounds, siderophores, extracellular hydrolytic enzymes and activation of plant defense system. We observed the formation of a methodology based on antagonistic compounds bioactivity to select efficient Actinobacteria to be used as biological control agents against phytopathogenic fungi. The use of multifunctional Actinobacteria has been proven to be efficient, not only by its natural protective activity against phytopathogenic fungi but also because of their ability to act as plant growth-promoting bacteria.
生物防治被认为是对抗植物病原体的一种可持续替代方法。在过去几年中，涉及放线菌作为植物病原真菌生物防治剂的研究不断增加，这促使我们去寻找过去五年中已被研究的放线菌属，并探索它们的抗真菌活性机制。检索工作在三个多学科数字平台上进行：PubMed/MedLine、科学网和Scopus。来自 、 、 、 、 、 、 属的放线菌，尤其是 属放线菌，通过多种抗菌机制表现出广泛的抗真菌谱，如产生天然抗真菌化合物、铁载体、细胞外水解酶以及激活植物防御系统。我们观察到基于拮抗化合物生物活性形成了一种方法，以选择高效的放线菌用作对抗植物病原真菌的生物防治剂。事实证明，使用多功能放线菌是有效的，这不仅是因为它们对植物病原真菌具有天然保护活性，还因为它们有能力作为促进植物生长的细菌发挥作用。
