A Root Disease of Piper nigrum L. in Sarawak caused by a Species of Phytophthora

Abstract

ROBERTSON1 reported a serious root disease of unknown cause on black pepper (Piper nigrum L.) in Sarawak which, post-war, first attracted attention in 19522. Sundararaman3, Venkata Rao4, and Chowdhury (personal communication, August 1956) stated that a Phytophthora sp. attacked pepper in India. In an Indian pepper survey, Krishna Menon5 found wilt diseases of this plant not serious, and obscure in origin. In Indo-China a Phytophthora sp. isolated by Barat6 from pepper was, apparently, not of primary importance. Muller7 showed that a wilt of the same plant in Indonesia was caused by a species of this genus. He named it P. palmivora var. piperis. In Malaya, Thompson8 isolated a member of the same genus from pepper roots sent to him from Sarawak in 1940.
