Apoyo a los procesos de monitoreo y reconocimiento de plagas y enfermedades en plantaciones de eucalipto en San Martin, Meta

Abstract

Phytosanitary monitoring in commercial plantations is one of the main preventive activities of an integrated management program. In forest commercial plantation established in San Martin, Meta (Colombia), a random exploratory sampling was achieved in the year 2019. Sampling included identification of damage, symptoms and signs in young trees (0 to 4 years-old) of Eucalyptus pellita, Eucalyptus grandis and the hybrid Eucalyptus urophylla x E. grandis. As a result, 15 phytosanitary problems caused by insects, fungi and bacteria, were recognized and assessed. The highest prevalence, was caused by leaf feeding ants: Atta sp. and the trunk borer: Microcerotermes exiguus, as well as the sap suckers species: Selenothrips rubrocinctus. Diseases caused by fungi were leaf spots by Coniella sp. and Cylindrocladium sp. and bacterial wilt caused by Ralstonia solanacearum. A more comprehensive sampling is necessary in order to establish the impact of each problem identified and plan accordingly to prevent and manage the dispersion.
