Technical Abstract: Downy mildew of chickpea and lentil is caused by species of Peronospora. The disease occurs in many parts of the world. All aerial parts of plants are susceptible. Main symptoms include white mycelial patches on the lower leaf surface, and chlorotic to yellow spots develop on the upper surface. Peronospora lentis causes downy mildew of lentil. Peronospora ciceris causes downy mildew of chickpea. The pathogens may also infect some of the other legume species, and produce oospores that survive adverse conditions. Management practices include cultural methods and application of fungicides. Some cultivars of chickpea show resistance or tolerance to the disease.
