Abstract

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.

Highlights

  • Faba bean (Vicia faba L.) is one of the oldest crops domesticated in the Fertile Crescent and is cultivated worldwide [1]

  • Integrative approaches such as phylogenetic characterization and genetic sequencing of isolates and determination of the genetic basis of virulence, detection of genes which are differentially expressed after infection of O. viciae, and profiling of the host cells, gene expression during O. viciae invasion will provide a framework to reveal the basis of pathogenicity and susceptibility in the faba bean–O. viciae interaction and help in the development of efficient faba bean gall” (FBG) disease management strategies

  • Faba bean gall is among the major constraints to faba bean production in Ethiopia

Summary

Introduction

Faba bean (Vicia faba L.) is one of the oldest crops domesticated in the Fertile Crescent and is cultivated worldwide [1] It is a diploid (2n 2x 12) cool-season legume species [2] having large genome size (∼13 Gb) with 85% of repeated sequences [3]. En, the use of crop rotation, intercropping, plant extracts, bioagents, compost tea, varietal resistance, elicitors-induced host resistance, and synthetic agrochemicals as effective control strategies to suppress the FBG disease pathogen are illustrated It illuminated how the advent of molecular markers, next-generation sequencing technologies, analysis of the molecular nature of the pathogen–host interaction, and race development could play key roles in advancing the knowledge of this plant pathogen infection process and disease management approaches to enhance yield. It illuminated how the advent of molecular markers, next-generation sequencing technologies, analysis of the molecular nature of the pathogen–host interaction, and race development could play key roles in advancing the knowledge of this plant pathogen infection process and disease management approaches to enhance yield. e main aim of this review is to provide an overview of research directions, which may help to tackle the FBG disease in Ethiopia, enhancing the faba bean production and productivity
