Emergent agricultural pathogens cause severe damage worldwide and their invasive potential is significantly increased by global trade, crop intensification and climate change. Standard surveillance and diagnostic protocols need to be evaluated and implemented, particularly with diseases caused by a wide range of pathogens that induce similar symptoms. Such is the case with Cassava Mosaic Disease (CMD) present in Africa and Asia, and associated with mixed virus infections and recombinant and re-assorted virus strains. CMD has been recently reported in Southeast Asia (SEA) and is already widely spread throughout this region. This communication offers an update on protocols and tools used to track the distribution of CMD and to characterize the pathogen associated with it in SEA.

东南亚新兴斯里兰卡木薯花叶病毒（Fam. Geminiviridae）的监测和诊断。

新出现的农业病原体在世界范围内造成严重破坏，其入侵潜力因全球贸易、作物集约化和气候变化而显着增加。需要评估和实施标准的监测和诊断协议，特别是对于由多种病原体引起的、引起类似症状的疾病。存在于非洲和亚洲的木薯花叶病 (CMD) 就是这种情况，并且与混合病毒感染以及重组和重新分类的病毒株有关。CMD 最近在东南亚 (SEA) 有报道，并且已经在整个地区广泛传播。该通讯提供了用于跟踪 CMD 分布并在 SEA 中表征与其相关的病原体的协议和工具的更新。
