Evaluation of Mycosphaerella impact on eucalypts plantations in Portugal
Mycosphaerella leaf disease (MLD) is one of the most important diseases of eucalypts plantations worldwide. However, only recently it has become relevant in Portugal. Caused by a complex of Mycosphaerella species, this disease reduces the photosynthetic area and can cause tree defoliation. In extreme cases it causes reduction in the volume of wood produced. In order to relate the observed symptoms of MLD with the presence of the pathogen and at the same time obtaining an evaluation of eucalypt clones and family susceptibility, two experimental plantations were established in places where the disease has been detected. Data on the percentage of affected crown (necrosis or defoliation) were collected and some of the Mycosphaerella species present were identified (M. africana, M. communis, M. grandis, M. lateralis, M. marksii, M. nubilosa, M. parva, M. vespa and M. walkeri).
