Technical Abstract: Ascochyta blight of chickpea is caused by the necrotrophic pathogen Ascochyta rabiei. The disease is a serious yield constraint of chickpea worldwide. The pathogen causes necrotic lesions on leaves, stems, flowers, pod and seeds under cool and humid conditions. The pathogen survives in crop debris in the fields and in infected seeds, and is spread by windblown ascospores in the spring and by splash rain during growing season. Partial resistance to the disease is available and in general small seeded chickpea express more resistance than large-seeded chickpea. Two pathotypes are recognized and can be managed through use of partially resistant varieties in combination of using effective fungicides.
