dc.description.abstract | El mal suramericano de las hojas del caucho Hevea brasiliensis es causado por el hongo ascomiceto Microcyclus ulei. El principal daño de la enfermedad es la defoliación prematura de las plantas y su impacto es de tal magnitud que una defoliación del 20% reduce la producción de látex en un 75%. El Microcyclus ulei ha sido la principal causa de fracaso de las grandes plantaciones de caucho en Brasil. En Colombia, si bien el ataque es conocido desde los años de 1970, no se tiene una estimación de la prevalencia del ataque ni de la severidad del mismo. En este estudio preliminar, llevado a cabo enjardines clonales del Meta (Cauchopar); Santander (Vivero ASOHESAN-Procaucho, Cimitarra; Jardín Clonal de Capote); Tolima (Biofábrica de Caucho, Guayabal) y Cúndinamarca (Biofábrica Eedecaucho: Guaduas) se encontró una prevalencia de 3.8%, siendo el clon RRIM600 el más afectado. En lo que respecta a la escala de afectación, los clones IAN710 y GT1 presentaron ataques más severos. | spa |
dc.description.abstract | The South American bleaf leaf of Hevea brasiliensis is caused by the fungus Microcyclus ulei. The major sympton is an early defoliation whose impact over rubber plantations is enormous: a 2% defoliation lead to a 75% reduction in latex production in the plantation. In fact, Microcyclus ulei has been the principal factor in the failure of big rubber plantations in Brazil. In Colombia, the attack by the fungus is well known since early 70's, but actually, there is no estiamtion of prevalence and severiry of attacks by M. Ulei. In the present study, carried out in clonal gardens of Meta (Cauchopar); Santander (vivero ASOHESAN-Procaucho, Cimitarra. Clonal garden at Campo Capote); Tolima (Biofábrica de caucho, Guayabal) and Cundinamarca (Biofábrica de Fedecaucho, Guaduas) we found a 3.8% of prevalence of Microcyclus ulei attacks, being RRIM600 clone the most affected one. Taking into account severity of the attacks, IAN710 and GT1 are the most affected among studied clones. | eng |
