Evaluación fitosanitaria del vivero forestal Cachí del Instituto Costarricense de Electricidad (ICE) presente en la cuenca media del río Reventazón.

Abstract

It was conducted a phytosanitary evaluation at the forest nursery in Cachi, property of Instituto Costarricense de Electricidad (ICE), which is located in the middle basin of the Reventazón River. Symptoms of major pests and diseases in the nursery were evaluated and described. In each case a sample of each injury was collected and moved to the Forest Patology Laboratory of Instituto Tecnológico de Costa Rica (ITCR), where its proper identification was made by using specialized techniques. A total of 27 species were evaluated of these only 14 phytosanitary pathologies were identified. Ascochyta sp. was present in four cases, Colletotrichum sp. and Pestalotiopsis sp. in three cases, also Oidium sp. and Phomopsis sp. were present in two cases. The most common type of injury found in the foliage of the host plants is the necrotic area. Nine damages found in the nursery were not identified in the laboratory, but those damages were described; the damages are also reported in this work. The “Guapinol” (Hymenaea coubaril) is the species that presented the highest rates of incidence and severity of the species tested in this work.
