%X Results are presented of a survey carried out in 2005 to assess the incidence of Phytophthora blight (PB, caused by Phytophthora drechsleri f.sp. cajani) in the major pigeon pea-growing states in the Deccan Plateau (DP) of India, i.e. Andhra Pradesh, Karnataka and Maharashtra. The survey of 190 farmers' fields in the 3 states revealed that PB was widespread irrespective of soil types, cropping systems and genotypes. Its incidence was higher in the low-lying fields than in the well-drained fields. The heavy unpredictable rains during July and August rendered the crop vulnerable to PB attack. However, it is still not clear how and where the PB pathogen survives and causes epidemics in pigeon pea in the DP. The survey indicates that the pigeon pea cultivars grown by farmers do not have adequate levels of resistance to PB, at least in the 3 states surveyed in the DP.
