Bacterial leaf blight (BLB) is a disease that can cause yield loss in rice plants. Control efforts can be carried out by increasing the resistance of plants to pathogenic infections by using elicitors in the form of salicylic acid compounds. This study aimed to determine the effect of salicylic acid application to the rice resistance against BLB disease. The research was carried out experimentally in planta in a screen house. The study consisted of pathogen inoculation and salicylic acid treatment with various concentrations (5, 10, 15 mM). The variables observed were pathogenicity, biochemical plant resistance, structural plant resistance, and plant growth. The results showed that there was a suppression of BLB disease intensity in rice infected by X. oryzae due to salicylic acid application. Exogenous salicylic acid correlated with the biochemical resistance increased, especially tannins and phenols, and structural resistance in the form of epidermal thickness and the number of stomata. However, salicylic acid does not affect the growth of rice plants.
