Manejo integrado de la pudrición negra en el cultivo de piña Ananas comosus Merr 1917, causada por Thielaviopsis paradoxa Moreau, 1952

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.
