摘要

咖啡(Coffea spp.)是世界上第二重要的商品,阿拉比卡咖啡是其最具代表性的品种。咖啡作物受到不同真菌病害的影响,这些病害减少了其叶片的光合活性面积和谷物的产量。从农艺学的重要性来看,由生物营养性病原菌半锈病引起的锈病是一种由于其繁殖类型而难以管理的疾病。另一种同样重要的病是丝枯病,由担子菌Ceratobasidium noxium (Syn. Corticium koleroga)和C. chavesanum引起,影响植物的所有空中组织。第三种病是由咖啡斑孢引起的斑孢叶斑病,它既影响叶子,也影响谷物,使其难以管理。虽然对锈病有足够的科学研究,但对丝状疫病的病因学、症状学、生命周期和防治知之甚少。使用了高分辨率照片和显微照片,并与现有的科学信息相关联。此外,还汇编了关于每种疾病的最新科学信息,并据此制定了生命周期。同样,本文描述了三种疾病的管理,主要基于遗传、文化、物理、生物和化学措施的使用,以及它们作为咖啡农业生态系统中可持续替代方案的整合。咖啡目前和未来面临的挑战包括品种评估、Ceratobasidium spp.和C. coffeicola的遗传多样性、植物-病原体相互作用以及农业生态管理措施。

Diseases affecting the coffee crop: Elucidating the life cycle of Rust,Thread Blight and Cercospora Leaf Spot
Coffee (Coffea spp.) is the second most significant commodity worldwide, with C. arabica being its most representative species. The coffee crop is affected by different fungal diseases that reduce the photosynthetically active area of its leaves and the production of grains. In order of agronomic importance, the rust caused by the biotrophic pathogen Hemileia vastatrix is a disease difficult to manage due to its type of reproduction. Another no less important, Thread Blight, caused by the basidiomycetes Ceratobasidium noxium (Syn. Corticium koleroga) and C. chavesanum, affects all aerial tissues of plants. The third disease, Cercospora leaf spot caused by Cercospora coffeicola, affects both leaves and grains, making it difficult to manage. Although there is enough scientific information on Rust, very little is known about the etiology, symptomatology, life cycle, and management of Thread Blight and Cercospora leaf spot. High-resolution photographs and micrographs were used and related with available scientific information. In addition, current scientific information on each disease was compiled, and with that, the life cycles were developed. Likewise, this manuscript describes the management of the three diseases based mainly on the use of genetic, cultural, physical, biological, and chemical measures and their integration as a sustainable alternative in the coffee agroecosystem. Current and future challenges in coffee include the evaluation of cultivars, genetic diversity of Ceratobasidium spp. and C. coffeicola, plant-pathogen interactions, and agroecological management practices.
