Aislamiento y caracterización del agente causal de pudriciones en el cultivo de Allium sativum L.

Abstract

Garlic (Allium sativum L.) is one of the crops with the smallest planting area in Ecuador due to its phytosanitary problems and the lack of quality seed bulbs. One of the factors that affects the production of this crop is the presence of diseases, among the most common is bulb rot. For this reason, the present investigation was proposed with the objective of identifying the causal agents that occur in the rotting of the garlic crop in the Pilahuín parish belonging to the Tungurahua province. Three isolates were obtained from infected bulb tissue, which were selected for cultural and morphological characterization. The results indicated that the causative agents of the most common rots were Fusarium oxysporum f.sp. cepae, Penicillium allii and Sclerotium cepivorum Berk. It is hoped that the results of these studies serve as a basis for the establishment of an integrated disease management program that leads to an increase in the garlic (Allium sativum L.) planting area in order to reach a supply in Ecuador.
