Eficacia de fungicidas para la pudrición de corona del fruto (Colletotrichum musae) de Banano (Musa AAA)

This investigative compilation was developed with the purpose of establishing information on the efficacy of fungicides for fruit crown rot (Colletotrichum musae) of Banana (Musa AAA). The main method of combating Colletotrichum spp is the use of synthetic chemicals. Fungicide resistance and regulatory pressure on pesticide residues and human health concerns are increasing. It was determined that fruit crown rot (Colletotrichum musae) develops especially in banana fruits, causing black or brown spots on their crown and that it occurs quickly in tropical areas with temperatures between 25 -30 0C; before the attack of the pathogen, the fruits cannot be commercialized, generating economic losses to the banana farmers; Farmers combat fruit crown rot by mixing fungicides from various chemical classes with aluminum ammonium sulfate. These fungicides include thiabendazole, imazalil, myclobutanil and azoxystrobin, which are used before packaging bananas and the results of research on various biological and botanical controls regarding Colletotrichum musae in bananas have not shown a favorable response, even proving the efficacy of chemical fungicides.

La presente recopilación investigativa, se desarrolló con la finalidad de establecer información sobre la eficacia de fungicidas para la pudrición de corona del fruto (Colletotrichum musae) de Banano (Musa AAA). El método principal para combatir Colletotrichum spp es el uso de productos químicos sintéticos. La resistencia a los fungicidas y la presión regulatoria sobre los residuos de pesticidas y las preocupaciones por la salud humana están aumentando. Se determinó que pudrición de corona del fruto (Colletotrichum musae), se desarrolla especialmente en frutos de banano, provocando manchas negras o marrones en su corona y que se produce rápidamente en zonas tropicales con temperatura entre 25 -30 0C; ante el ataque del patógeno, los frutos no pueden ser comercializados, generando pérdidas económicas a los agricultores bananeros; los agricultores combaten la pudrición de la corona de la fruta mezclando fungicidas de varias clases químicas con sulfato amónico de aluminio. Estos fungicidas incluyen tiabendazol, imazalil, miclobutanil y azoxystrobin, que se utilizan antes del empaque del banano y los resultados de investigaciones sobre diversos controles biológicos y botánicos referente a Colletotrichum musae en banano no han mostrado respuesta favorables, comprobándose aun la eficacia de los fungicidas químicos.
