The Biology, Ecology, Pathology and Control of Mycosphaerella Leaf Blights in Australian Eucalypt Plantations.

澳洲桉树叶枯病的生物学、生态学、病理学及防治。由真菌菌引起的叶斑病在西澳大利亚超过15万公顷的蓝桉树种植园中广泛传播，造成幼树冠层面积严重减少。本项目将通过研究前期项目中鉴定的主要致病性支球菌菌种的生命周期、孢子传播的方式和时间、感染过程和宿主特异性，研究这些疾病的流行病学。叶斑病的经济影响将通过大型排除试验进行评估。将制定和评估一套预测性的综合管理方案，以最大限度地减少霉菌叶面疾病的影响。

The Biology, Ecology, Pathology and Control of Mycosphaerella Leaf Blights in Australian Eucalypt Plantations. Leaf spot diseases, caused by Mycosphaerella, have become widespread in over 150,000 ha of Eucalyptus globulus (blue gum) plantations in Western Australia, causing severe reduction in canopy area of young trees. This project will research the epidemiology of these diseases by studying the life cycles of the key pathogenic Mycosphaerella species identified in a previous project, modes and timing of spore dispersal, the infection process, and host specificity. The economic impact of leaf spot diseases will be assessed from large exclusion trials. A predictive integrated management package for Mycosphaerella foliar diseases will be formulated and evaluated to minimising disease impact.
