Abstract

First report of Phytophthora heveae and Pythium spp. on tropical tree seedlings in Panama.

Abstract

In Panama in 1995, damping-off was observed on Anacardium excelsum and Tetragastris panamensis within a lowland tropical rain forest. Disease impact was greatest during the wet season, causing 40.7% mortality of T. panamensis seedlings during the 1995 wet season and 68% A. excelsum seedling mortality during the 1996 wet season. Pythium vexans, Pythium splendens, Pythium chamaehyphon [P. chamaihyphon] and Phytophthora heveae were identified from diseased A. excelsum seedlings. P. vexans accounted for 70% of the Pythium spp. isolates. This is the first report of Phytophthora heveae and Pythium spp. on A. excelsum and T. panamensis seedlings.
