Abstract
Abstract Phytophthora blight caused by Phytophthora drechsleri f. sp. cajani is a major production constraint to pigeonpea in India. The disease has also been reported from other countries. It was first reported in 1966 from India and is currently considered to be more important in short‐duration pigeonpeas than in traditional medium‐ and long‐duration types. Little work has been done on disease epidemiology and management. Screening methods have been standardized and work on host‐pathogen interaction indicates that the blight pathogen is variable and that high and stable sources of resistance have not so far been located in the cultivated germplasm. We present a critical analysis of research conducted on this disease and strategies for disease management and future research priorities are suggested.
