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.
