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.
