为了明确水杨酸对烟草野火病的抑制效果及其对烟草生物学性状的影响，采用田间随机排列设计，进行病情调查和生物学性状调查。结果表明：与对照药剂、赤霉素以及胺鲜酯处理相比，水杨酸处理对诱导烟草抵抗野火病具有较好的效果，3次处理后的防控效果可达71.90%；且水杨酸处理对烟株叶片数、株高、茎围以及最大叶面积等烟草主要生物学性状指标无毒副作用。水杨酸可以作为一种烟草生产上的诱导抗病物质，一定程度上达到对烟草野火病的防控效果。

Plot experiment was carried out to study efficiency of salicylic acid in inducing tobacco to resist wildfire disease (Pseudomonas syringae pv. tabaci) and its influence on tobacco agronomic characters. Results show that:contrasted with common bactericide, gibberellin and Diethyl aminoethyl hexanoate treatments, salicylic acid has the best efficiency on resisting wildfire disease, and the effect was 71.90%after treated thrice. Salicylic acid has no obvious differences on the number of leaves, height and stem girth and its maximal leaf area when compared with water control. Salicylic acid can be applied in tobacco production as an induced resistant material, which, to some extent, has a better efficiency on inhibiting tobacco wildfire disease.
