Manejo de Antracnosis (Colletotrichum sp.) en el cultivo de guanábana (Annona muricata L.)

This document compiled relevant information on the management of Anthracnose (Colletotrichum sp.) in the cultivation of soursop (Annona muricata L.). Anthracnose causes black rot of fruit and affects all stages of fruit development, mainly in the soft tissues. The fruit mummifies and falls off; in nursery plantations it occurs causing necrosis of the branch neck and the branch tip. In addition, it was determined that the fungus Colletotrichum sp. it attacks plantations from the nursery stage to the final site or plants in production, affecting leaves, flowers, shoots, branches and fruits, with lesions that start small and are dark brown in color and increase to a black hue; environmental conditions, such as high rainfall, promote the development of the pathogen; the branches attacked by Colletotrichum are the cause of the black rot of the fruit and the control can be carried out by eliminating or burning infected fruits and plants and also by pruning, together applying fungicides based on copper hydroxide, mancozeb or chlorothalonil

El presente documento recopilo información relevante sobre el manejo de Antracnosis (Colletotrichum sp.) en el cultivo de guanábana (Annona muricata L.). La antracnosis causa pudrición negra de la fruta y afecta todas las etapas de desarrollo de la fruta, principalmente en los tejidos blandos. El fruto se momifica y se cae; en plantaciones de vivero se presenta provocando necrosis del cuello de la rama y de la punta de la rama. Además se determinó que el hongo Colletotrichum sp. ataca a las plantaciones dese la etapa de vivero hasta sitio definitivo o plantas en producción, afectando hojas, flores, brotes , ramas y frutos, con lesiones que inician pequeñas de color café oscuro y que van aumentando hasta tonalidad negra; las condiciones ambientales, como el caso de las altas precipitaciones, promueven el desarrollo del patógeno; las ramas atacadas por Colletotrichum son las causantes de la podredumbre negra del fruto y el control puede realizarse eliminando o quemando frutos y plantas infectadas y además realizando podas, conjuntamente aplicando fungicidas a base de hidróxido de cobre, mancozeb o clorotalonil.
