First report of Pindo palm heart rot caused by Ceratocystis paradoxa in China.

Abstract

In January 2012, a novel disease with an incidence of 50% was discovered in Pindo palm (Butia capitata) from the Coconut Grant View Garden in Wenchang, Hainan Province (China). Diseased leaflets at the base of the rotted heart leaves had reddish brown lesions. When the infection progressed, the leaves turned yellow and became blighted from the inner to the outer part of the crown. Once the growing point was destroyed, the entire tree ultimately died. the causal pathogen was identified as Ceratocystis paradoxa based on cultural, morphological, genetic (ITS) and pathogenicity analyses. This is thought to be the first report of Pindo palm heart rot caused by C. paradoxa in China.
