Distribution of common bacterial blight and anthracnose diseases and factors influencing epidemic development in major common bean growing areas in Ethiopia
Common bean is an important legume consumed as a source of food and used as a cash crop worldwide. However, its production and productivity are mainly constrained by bacterial and fungal diseases.

| description | Common bean is an important legume consumed as a source of food and used as a cash crop worldwide. However, its production and productivity are mainly constrained by bacterial and fungal diseases. A field survey was conducted to determine the prevalence, incidence, severity and association of factors influencing common bacterial blight (CBB) and anthracnose epidemics in major bean growing areas of Ethiopia, during 2019. In three regions within six zones from 12 districts, a total of 180 common bean fields were assessed for CBB and anthracnose. The results revealed that CBB and anthracnose were 100% prevalent though CBB was more severe than anthracnose. The logistic regression model showed CBB and anthracnose components were significantly associated with biophysical factors. High CBB incidence (>70%) at Ambo, Arsi-Negele and Shashemene-zuriya and high severity (>30%) at Ambo, Boricha and Shahsemene-zuriya were strongly associated with sole cropping, July sowing, poor weeding practices, maturity stage and own saved seeds. Anthracnose incidence of >50% and severity of >30% had high probabilities of associations with zones, sole cropping, own saved seeds, variety, poor weeding practices and maturity stages. The study indicated that CBB and anthracnose are severe and 100% prevalent in Ethiopia, and efforts should be done towards the usage of clean seeds, weeding practices, following appropriate sowing dates and other appropriate agronomic practices to manage the diseases. |
