Isolation and identification of the mold that causes anthracnose in musa paradisiaca l. (plantain) in cooperative san carlos, el salvador and isolation of molds and yeasts with antagonistic capacit

Abstract

Anthracnose is a disease caused by a variety of fungi, the species to vary according to the weather and environmental conditions of each country, this disease affects the banana fruits by reducing their quality and shelf life and as consequence they cause losses for farmers In El Salvador this disease is control with pesticides that pollute the environment and expose the health of the workers and consumers. The few studies under in El Salvador about the identity of the fungi that affect the bananas with this disease reduce the possibility of implementing alternatives of control for this disease. This investigation focused on the isolation and identification of the fungus causing anthracnose with higher pathogenicity, the study was carried out in banana plantations of Cooperativa San Carlos El Paisnal, El Salvador. The ability of the isolates to cause lesions in banana fruit was demonstrated and, from the values obtained, the microorganism with the highest pathogenicity was selected and a molecular identification was made, obtaining as a result that the disease is caused by the species of Fusarium dimerum. Also, isolation of fungi candidates for antagonists was carried out, and was isolated a yeast with a capacity of 100% inhibitory for the pathogenic species Fusarium dimerum.
