Abstract

A study was made on the disease incidence in four pejibaye

heart of palm varieties during the first 12 months of

development in the field. Three of the varieties were

spineless (Diamantes-1, Diamantes-10 y Diamantes-20) and

one was spiny (Utilis-Tucurrique). The trial was carried out

in Guápiles, Caribbean region of Costa Rica. The pathogens

found were the fungi Colletotrichum sp. (Black leaf spot),

Phytophthora palmivora (Rotting of the spear leaf),

Drechslera setariae (Ring spot), Lasidioplodia thebromae

(Frayed leaf) and the bacteria Erwinia sp. (Rotting of the

stem apex). The Diamantes-10 was consistently and

significantly less susceptible and Utilis-Tucurrique more

susceptible. But in neither case, the diseases reached a level

of economic importance. Erwinia and Phythophthora showed

a relationship of higher incidence with higher rainfall and

temperature.
