Abstract
Severe losses of plants in crops of Telosma cordata occurred in Nam Dan District, Nghe An Province, Vietnam, following prolonged wet weather in September 2007. Phytophthora palmivora was isolated consistently from the margin of diseased and healthy tissue in underground stems. Koch’s Postulates were fulfilled. This is the first report of this disease.
