| dc.description | Black rot is the disease of greatest economic importance in pineapple cultivation; This pathogen is very aggressive and can cause yield losses of up to 70% under favorable weather conditions. This research was developed as a non-experimental component of a bibliographic nature, through a technique of analysis, synthesis and summary of the information obtained. From what was previously detailed, it was determined that this disease mainly affects the fruit, although it can occur in different parts of the plant; In conditions of high humidity and strong wind, white and yellow spots will appear on the leaves. Ripe fruits affected by the fungus T. paradoxa decompose completely, soften the tissue, acquire a watery consistency and a yellow-brown color; In this state you can smell the pleasant aroma of glucose fermentation; The shell is light brown, watery, soft to the touch, and breaks when lightly pressed to allow the liquid inside to escape. In the field, sampling should be carried out to find suspicious symptoms of black rot disease in pineapple. The fungus T. paradoxa produces conidia that are spread by wind, rain splashes, wounds or damaged tissues, as well as by work tools. T. paradoxa is a phytopathogen that causes severe damage to pineapple crops not only during the postharvest period but also during harvest; Therefore, there is a need to develop effective measures to control plant pathology and correctly and effectively identify the causative factors for greater control. | es_ES |

| dc.description.abstract | La pudrición negra es la enfermedad de mayor importancia económica en el cultivo de piña; este patógeno es muy agresivo y puede provocar pérdidas de rendimiento de hasta el 70 % en condiciones climáticas favorables. La presente investigación se desarrolló como componente no experimental de carácter bibliográfico, mediante una técnica de análisis, síntesis y resumen de la información obtenida. Por lo anteriormente detallado se determinó que esta enfermedad afecta principalmente al fruto, aunque puede presentarse en diferentes partes de la planta; en condiciones de alta humedad y viento fuerte, aparecerán manchas blancas y amarillas en las hojas. Los frutos maduros afectados por el hongo T. paradoxa se descomponen completamente, reblandecen el tejido, adquieren una consistencia acuosa y un color amarillo-marrón; en este estado se puede oler el agradable aroma de la fermentación de la glucosa; la cáscara es de color marrón claro, acuosa, suave al tacto y se rompe cuando se presiona ligeramente para permitir que escape el líquido del interior. En campo se debe realizar muestreos para encontrar síntomas sospechosos de la enfermedad pudrición negra en la piña. El hongo T. paradoxa produce conidios que se propagan por el viento, salpicaduras de lluvia, heridas o tejidos dañados, así como por herramientas de trabajo. T. paradoxa es un fitopatógeno que causa severos daños a los cultivos de piña no solo durante el período de poscosecha sino también durante la cosecha; por lo tanto, existe la necesidad de desarrollar medidas efectivas para controlar la patología vegetal e identificar correcta y efectivamente los factores causantes para un mayor control. | es_ES |
