Interpretive Summary: Alternaria blight of chickpea is a minor disease and occurs sporadically. It may cause serious damage to chickpea crops under specific conditions. It is caused by the fungal pathogen Alternaria alternata, and it affects all above ground tissues. Control measures include cultural practices and applications of fungicides. Resistant cultivars are available.

Technical Abstract: Alternaria blight of chickpea is caused by the fungal pathogen Alternaria alternata. The pathogen has wide host range, and affects all above ground parts of the plant. The disease occurs sporadically and occasionally could be economically important and causes significant damage. The pathogen can be seed borne, which serves as primary inoculum. Secondary spread is mainly by airborne conidia. The pathogen is favored by cool and moist conditions. All chickpea plant growth stages are susceptible, and susceptibility increases with plant age. Resistant cultivars are available and planting resistant cultivars is an important strategy in managing the disease, in combination with adjusting plant density and application of fungicides.
