Alternaria porri causes purple blotch disease in onion and beneficial fungi of the genus Trichoderma can be used for its biocontrol, but knowledge of the mechanisms of the defense response in the interaction of onion plants with Trichoderma and A. porri is limited. In this study, the activity of defense enzymes: glucanases, chitinases, catalases and peroxidases in onion plants in the interaction with the isolate To of Trichoderma asperellum and A. porri was evaluated. The isolate To of T. asperellum was selected because it stood out for its antagonistic activity against A. porri compared to that of another isolate of T. asperellum (TC1 and TC2) and of T. harzianum and T. atroviridae. With the method of dual culture and cellophane paper, the isolate To inhibited the mycelial growth of A. porri in 56 and 53%, respectively and showed mycoparasitic activity. The activity of enzymes depended on the interaction of onion plants with the isolate To of T. asperellum and A. porri. The activity of glucanases and chitinases increased with the isolate of T. asperellum and was repressed with A. porri. The activity of catalases was induced with A. porri and the activity of peroxidases increased with both microorganisms. In conclusion, the defense mechanisms of onion plants are regulated by the interaction with T. asperellum and A. porri and both microorganisms; aspect to be consider in the biocontrol of onion pathogens with the isolate To of T. asperellum.
