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.

澳大利亚桉树人工林球腔菌叶枯病的生物学、生态学、病理学及防治由球腔菌属（Mycosphaerella）引起的叶斑病在西澳大利亚超过150，000公顷的蓝桉（Eucalyptus globulus）（蓝桉）种植园中广泛传播，导致幼树冠层面积严重减少。该项目将通过研究在以前的项目中确定的主要致病球腔菌属物种的生命周期、孢子传播的模式和时间、感染过程和宿主特异性来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球腔菌属叶部疾病综合管理方案，以最大限度地减少疾病影响。
