Abstract

During a disease survey in Puerto Rico conducted from 2008 to 2010, 50% of the inflorescences were affected with inflorescence wilt and flower and vascular necrosis in 70% of the fields of rambutan and longan at the USDA-ARS Research Farm in Isabela, 3 commercial orchards and the Mango Germplasm Collection of the University of Puerto Rico's Experiment Station in Juana Diaz. The causal pathogen was identified as Albonectria rigidiuscula based on cultural, morphological, genetic (ITS and PCR) and pathogenicity analyses. This is thought to be the first report of A. rigidiuscula causing inflorescence wilt and vascular and flower necrosis in rambutan, longan and mango.
