Faba Bean Gall (Olpidium viciae K.) as a Priority Biosecurity Threat for Producing Faba Bean in Ethiopia: Current Status and Future Perspectives

Birhanu Kahsay Meresa,Hailay Mehari Gebremedhin

The diploid cool-season legume species, faba bean (Vicia faba L.), is one of the vital pulses for the people in the world as it maintains the sustainability of agriculture and provides nutrient-rich grains. Biotic and abiotic stresses are, however, challenging the faba bean production in many countries. The foliar diseases of faba bean are among the major constraints for the production and productivity of faba bean. Recently, a new foliar disease “Faba bean gall” caused by plant debris and soil-borne pathogen (Olpidium viciae K.) is rapidly spreading and causing high yield losses in Ethiopia. This review paper presents the distribution, impact, epidemiology, and biology of faba bean gall pathogen and principally illustrates how the application and investigation of the various diseases’ management approaches such as avoiding crop residues, crop rotation, intercropping, use of elicitors to induce host resistance, use of resistant genotypes, bioagents, compost teas, plant extracts, and lastly use of chemical fungicides could be important to control the faba bean gall disease underlying in faba bean.
