叶片红条及顶端腐烂是重点观察内容，可单独或同时出现。茎内部红变、叶片条纹和枯心需分开记录。
Red leaf stripes and top rot may occur separately or together. Record leaf symptoms, spindle injury and internal stalk discoloration as separate findings.

症状与危害
DAMAGE AND SYMPTOMS
叶片红条及顶端腐烂是重点观察内容，可单独或同时出现。茎内部红变、叶片条纹和枯心需分开记录。
Red leaf stripes and top rot may occur separately or together. Record leaf symptoms, spindle injury and internal stalk discoloration as separate findings.
来源与传播
ORIGIN AND SPREAD
病原是细菌，温暖潮湿有利发病。对某块田的传入来源，需要结合种源、既往病史和检测调查，不能根据天气直接推断。本稿不指定尚未核实的自然侵入门户。
The pathogen is bacterial, and warm, moist weather favours disease. Establishing a particular field’s infection source needs investigation; weather alone cannot identify it. This draft does not assert an unverified entry route.
生活史与机理
LIFE CYCLE AND BIOLOGY
微观图用细菌和受损组织表示感染过程，不使用虫卵、菌丝或病毒粒子。图为原理示意，并非本田检出的病原照片。
The inset depicts bacteria and affected tissue, not insect eggs or virus particles. It is an explanatory schematic, not evidence that the pictured field has tested positive.
检查与确认
HOW TO INSPECT AND CONFIRM
查看叶条与心叶基部，记录时间和分布；与叶灼病等区分。按诊断机构要求采集代表样品，提交品种和田块资料。
Inspect stripes and the spindle base, recording dates and distribution. Consider leaf scald and other causes. Submit representative samples with field and cultivar information to a diagnostic service.
预防、治理与复查
PREVENTION, MANAGEMENT AND FOLLOW-UP
抗性品种是核心防控途径；本病并非主要由机械设备传播，不能照搬宿根矮化病的器械传播叙事。确诊后采取当地适用措施，并跟踪新增病株。
Resistant cultivars are central to control. SRA notes that equipment is not the primary means of spread, so the ratoon-stunting narrative should not be copied here. Confirm the diagnosis, obtain local advice and monitor new cases.
