Objective: To evaluate the effect of three resistance inducers and an organic fertilizer on the titles of CandidatusLiberibacter asiaticus in Citrus sinensis (L.) Obseck cv. Valencia.Design/methodology/approach: The treatments consisted of Vacciplant Max and UPL-08, Fosetil aluminum. Likewise, BIO-FOM was applied on the periphery of the trees, with moisture for nutrients absorption. The evaluated variables were fruit weight, equatorial diameter, skin thickness, °BRIX, severity and chlorophyll, in each of the five treatments, which consisted of 20 repetitions.Results: The fruits of the trees treated with Vacciplant Max had lower skin thickness and a higher °BRIX. Also, the highest chlorophyll index was recorded with BIO-FOM fertilizer. However, none of the evaluated treatments significantly decreased the fruit harshness.Findings/conclusions: The best treatment against Huanglongbing was fosetyl aluminum which conferred greater fruit weight and diameter
