This review covers, for the first time, all methods based on the use of strains as biocontrol agents for the management of plant diseases caused by fungi and oomycetes. Atoxigenic strains have been screened in a variety of hosts, such as peanuts, maize kernels, and legumes, during the preharvest and postharvest stages. These strains have been screened against a wide range of pathogens, such as , , and species, suggesting a broad applicability spectrum. The highest efficacies were generally observed when using non-toxigenic strains for the management of mycotoxin-producing strains. The modes of action included the synthesis of antifungal metabolites, such as kojic acid and volatile organic compounds (VOCs), secretion of hydrolytic enzymes, competition for space and nutrients, and induction of disease resistance. strains degraded sclerotia, showing high control efficacy against this pathogen. Collectively, although two strains have been commercialized for aflatoxin degradation, a new application of strains is emerging and needs to be optimized.
这篇综述首次涵盖了所有基于利用 菌株作为生防剂来防治由真菌和卵菌引起的植物病害的方法。在收获前和收获后阶段，已经在各种宿主（如花生、玉米粒和豆类）中筛选了产无毒素的 菌株。这些菌株已经针对广泛的病原体进行了筛选，如 、 和 等物种，表明其具有广泛的适用性。在管理产真菌毒素的菌株时，通常使用非产毒 菌株可获得最高的防治效果。作用模式包括合成抗真菌代谢物，如曲酸和挥发性有机化合物（VOCs），分泌水解酶，竞争空间和营养物质，以及诱导抗病性。 菌株可降解菌核，对该病原体表现出很高的防治效果。总的来说，虽然已经有两种 菌株商业化用于降解黄曲霉毒素，但 菌株的新应用正在出现，需要进一步优化。
