Common bean (Phaseolus vulgaris L.) is important legume crop world-wide and in Ethiopia for its multipurpose uses. Common bean rust, is the most destructive fungal disease that severely reduces bean yield. For years, rust appeared in a farmer's field in Southern Ethiopia; however, the disease's significance remains unclear. The research aimed to ascertain the distribution and intensity of common bean rust, as well as elucidate the association of biophysical parameters. The field survey was conducted in southern Ethiopia in 2022. Ninety percent of the 78 commonbean fields were affected by common bean rust. Mareko, Meskan, Duguna Fango, Damot Woide, and Demba Gofa had 100% of the fields affected, and Boricha had 90%. Damot Woide and Lanfuro had the highest and lowest mean rust incidence rates, respectively, 59.2% and 22.5%. Duguna Fango had the highest rust severity (35.5%), while Lanfuro had the lowest (13.5%). In the research areas, the biophysical factors, either alone or in combination, have a significant impact on the intensity of common bean rust. The current investigation verified the distributionand the association biophysical factors with common bean rust. In addition, the survey of the disease and the identification of factors should continue over time and space.
菜豆（Phaseolus vulgaris L.）是一种重要的豆类作物，在全世界和埃塞俄比亚都因其多用途而被广泛种植。菜豆锈病是最具破坏性的真菌病害，可严重降低菜豆的产量。多年来，锈病一直在埃塞俄比亚南部的一个农民的田地中出现，但该病的重要性仍不清楚。本研究旨在确定菜豆锈病的分布和严重程度，并阐明生物物理参数的关联。该田间调查于 2022 年在埃塞俄比亚南部进行。78 个菜豆田中有 90%受到菜豆锈病的影响。Mareko、Meskan、Duguna Fango、Damot Woide 和 Demba Gofa 的所有田地都受到影响，而 Boricha 仅有 90%受到影响。Damot Woide 和 Lanfuro 的平均锈病发生率最高和最低，分别为 59.2%和 22.5%。Duguna Fango 的锈病严重程度最高（35.5%），而 Lanfuro 的锈病严重程度最低（13.5%）。在所研究的地区，生物物理因素单独或组合对菜豆锈病的严重程度有重大影响。本研究验证了菜豆锈病的分布和与生物物理因素的关联。此外，应该随着时间和空间的推移，继续对该疾病进行调查和识别相关因素。
