Abstract

Alternaria cerealis is the first record as a phytopathogen in tomato plants (Solanum lycopersicum L). This fungus has been identified as A. cerealis MT808477 in Egypt. In the present work, Trichoderma harzianum was used to control the leaf spot disease caused by A. cerealis at different concentrations of inoculum (105 and 107 spores/mL) in infected or non-infected plants after 2, 24, and 48 h. The interaction of T. harzianum is to enhance the redox buffer capacity to suppress A. cerealis infection and to stimulate many chemical signals that cause a considerable increase in the activity of some chemical defense. Polyphenol oxidase activity was increased in infected tomato plant, whereas its activity was significantly decreased after T. harzianum treatments. T. harzianum played a vital role in the resistance of tomato plants against A. cerealis leaf spot disease by enhancing the redox buffer capacity. The results indicated that the improvement of plant tolerance, activation of plant defense systems, modification of oxidative damage, and antioxidant mechanism varied with the type and duration of stress. Also, T. harzianum mediated protection against A. cerealis. This behavior may be associated with the alleviation of the oxidative burst in tomato leaves.
