Etiología de la necrosis apical, cancros y muerte de ramas en mango (Mangifera indica L.) en los Cantones Bolívar y Santa Ana

Abstract

Mango (Mangifera indica L.), belonging to the Anacardiaceae family, is a crop found in the tropics and subtropics, and marketed as fresh or processed fruit. The cantons of Santa Ana and Bolívar are considered the main mango producing areas in the province of Manabí. Several phytosanitary problems were observed on several farms in both cantons, mainly symptoms of apical necrosis, dieback and cankers. For this reason, the present work aims to identify the causal agent of these symptoms at the gender level. 45 mango plant samples were collected from different areas of Manabí, which were transferred to the Phytopathology laboratory where the respective process was carried out to obtain the fungal isolates. It was possible to identify the Botryosphaeriacea family as responsible for the formation of the aforementioned symptoms and confirmed by Koch's postulates. It is expected that in future research it will be possible to achieve an identification at the species level to subsequently provide greater knowledge of the genera found, which will subsequently allow for the creation of management plans for the diseases that these organisms cause in mango cultivation.
