Coconut Cadang-Cadang

Abstract

``Cadang-cadang'' is derived from a word in the Bicol dialect, ``gadan-gadan, '' which means dead or dying (Rillo and Rillo, 1981). It now refers to a premature decline and death of coconut palms in the Philippines that is associated with viroid infection (Fig. 1). The synonym ``yellow mottle decline'' is not commonly used, and ``tinangaja'' is the name used for a similar disease with the same etiology in Guam (Boccardo et al.,1981; Boccardo, 1985).
