Abstract

L. is considered one of the most essential legume crops in Kenya. is an economically significant plant pathogen that causes Alternaria leaf spot which accounts for over 70% yield losses of beans in Kenya. Chemical fungicides based on copper and sulfur are used to control Alternaria leaf spot in bean plants, but their prolonged use has adversely affected the environment and the health of workers. Herein, we tested the biocontrol potential of bacterial agents from soil planted with Rosecoco bean plants infected with . Using bacterial suspensions at different time intervals, we evaluated the putative bacterial biocontrol activity against under greenhouse conditions. and bacterial biocontrol agents significantly suppressed disease severity by 20% and 21.2% on the 45 day, respectively. Our study demonstrates that and are promising biocontrol agents that could be integrated in the management of Alternaria leaf spot.

摘要

L.被认为是肯尼亚最重要的豆类作物之一。是一种具有经济重要性的植物病原体，可引起链格孢叶斑病，该病导致肯尼亚豆类产量损失超过70%。基于铜和硫的化学杀菌剂被用于控制豆类植物中的链格孢叶斑病，但其长期使用对环境和工人健康产生了不利影响。在此，我们测试了来自种植有感染了的罗塞科豆植物的土壤中的细菌制剂的生物防治潜力。在不同时间间隔使用细菌悬浮液，我们在温室条件下评估了假定的细菌对的生物防治活性。和细菌生物防治剂在第45天分别显著抑制病害严重程度20%和21.2%。我们的研究表明，和是有前途的生物防治剂，可用于链格孢叶斑病的综合管理。
