Summary or description

"La enfermedad del permanente del tomate causada por Candidatus Liberibacter solanacearum (CaLso), en los últimos años ha sido de gran importancia para las regiones productoras de tomate en México, causando pérdidas considerables (60 %) y un complicado manejo del vector y la bacteria. Por lo anterior, el objetivo del presente trabajo fue determinar el efecto inductor de los fosfitos (Phi) sobre tomate bajo invernadero inoculado con Candidatus Liberibacter solanacearum. Las plantas de tomate infectadas con CaLso, fueron tratadas con Phi, Acibenzolar S-metil y ácido salicílico; se evaluó la disminución de la severidad de los síntomas y los parámetros agronómicos. Los resultados indican que los Phi redujeron la severidad del permanente del tomate en la planta, destacando los Phi en altura de planta (ALTP), peso del fruto (PF), peso fresco (PFP) y peso seco de planta (PSP) y peso fresco y seco de raíz (PFR, PSR), destacando los Phi sobre el acibenzolar S-metil (ASM), ácido salicílico (AS) e inoculado con Bactericera-Candidatus (IBC)"

"The disease “permanente del tomate” associated by Candidatus Liberibacter solanacearum (CaLso), in last years has been of great importance for tomato producing regions in Mexico, causing considerable losses (60 %) and complicated management of the vector and bacteria. Therefore, the objective of this work was to determine the effect of phosphites (Phi) on the growth of tomato inoculated with Candidatus Liberibacter solanacearum. The tomato plants infected with CaLso were treated with phosphites, Acibenzolar and salicylic acid; the decrease in the severity of symptoms and agronomic parameters was evaluated. The results indicate that phosphites reduced the severity in the tomato plant, highlighting phosphites in plant height (ALTP), fruit weight (PF), fresh weight (PFP) and dry plant weight (PSP) and root, highlighting phosphites on acibenzolar S-methyl (ASM), salicylic acid (AS) and inoculated with Bactericera-Candidatus (IBC)"
