Abstract
Objective: evaluate the effect of three resistance inducers and an organic fertilizer on the titles of Candidatus Liberibacter asiaticus in Citrus sinensis (L.) Obseck cv. Valencia.
Diseño/metodología: The treatments consisted of Vacciplant Max and UPL-08, Fosetil aluminio. Likewise, BIO-FOM was applied on the periphery of the tree, presenting moisture for the absorption of nutrients. The variables evaluated 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 trees treated with Vacciplant Max had lower shell thickness and a higher °BRIX content. In addition, the highest chlorophyll index was achieved with BIO-FOM fertilizer. However, none of the evaluated treatments significantly decreased the severity percentage.
Findings/conclusions: The best treatment against Huanglongbing was fosetyl aluminio by conferring greater fruit weight and diameter.
