DELGADO-ORTIZ, Juan Carlos et al. Candidatus Liberibacter solanacearum vascular pathogen of solanaceae: Diagnosis and control. TIP [online]. 2019, vol.22, e177.  Epub Mar 04, 2020. ISSN 1405-888X.  https://doi.org/10.22201/fesz.23958723e.2019.0.177.

Candidatus Liberibacter solanacearum is a Gram-negative bacterium, obligate parasite of the phloem in Solanaceus crops, not cultivable in vitro. It is transmitted vertical and horizontally by Bactericera cockerelli. In Mexico, CLso is a pathogen asociated with the diseases "permanente del tomate", "punta morada de la papa" (Zebra chip) and "variegado del chile". The symptoms caused by CLso depend on the farming and the stage of growth of the host but it mainly consists in yellowing and deformation of the leaf blade, due to the feeding of the vector and the colonization of the pathogen. Infections caused by CLso reduce the quality and the commercial value of the product in the market. The presence of this bacterium has been detected in the states of Coahuila, Sinaloa and Guanajuato Mexico through molecular techniques, the control of the diseases is focused on the control of the vector, by means of cultural practices and the application of chemical and biological agents. Therefore, the objective of this work is to stand out the current situation of the distribution of CLso in Mexico, the diagnostic methods and the strategies for the integrated management of the disease and the vector.
