Abstract: | Trichoderma harzianum is a widely distributed soil fungus that antagonies numerous fungal phytopathogens. In this study, interactions between theT. harzianum isolates andAscochyta rabiei in experiments on agar growth medium were studied. All testedT. harzianum isolates produced metabolite that inhibited growth ofA. rabiei the agent of ascochyta blight disease of chickpea in culture. Isolates ofT. harzianum produced chitinase and β-1,3-glucanase when grown in liquid cultures containingA. rabiel cell wall, laminarin and chitin as sole carbon sources. Levels higher of these enzymes were induced inT. harzianum T15 isolate. |
