Phytophthora Blight Of Pigeon Pea In India uri icon

abstract

  • Isolations were made from blighted pigeon-pea (Cajanus cajan) plantsfrom different locations in India. A species of Phytophthora was consistentlyobtained from these locations and was proved to be the causalorganism involved in the disease. Based on the sporangium shape andsize, oogonium and oospore formation, temperature requirements, andpathogenicity tests, we have classified these isolates as P. drechsleri f. sp.cajani. The use of formae speciales was considered appropriate becauseof the specificity of these isolates to pigeon pea and Atylosia spp., wildrelatives of the pigeon pea
