Antecedentes: Las especies del género Mortierella prosperan usualmente como saprófitas en el suelo y materia orgánica de diversos ecosistemas forestales. Tradicionalmente, se han aislado de los sistemas radicales de diversas especies vegetales. Adicionalmente, investigaciones realizadas en suelo de cultivo de aguacate para lograr la purificación de Pythophthora. cinnamomi indican que Mortierella spp. son hongos contaminantes, sin mencionar su patogenicidad.
Objetivo: Esta investigación tuvo como objetivo identificar la presencia de Mortierella sp. y evaluar su posible patogenicidad en el cultivo del aguacate.
Métodos: Las cepas se aislaron de suelo de huertas ubicadas en los principales municipios productores de aguacate en el estado de Michoacán. Las cepas fueron identificadas y se sometieron a pruebas de patogenicidad con plantas de aguacate de tres meses de edad y con plántulas con seis hojas verdaderas.
