Biological Control of Rhizoctonia solani Damping-Off with Wheat Bran Culture of Trichoderma harzianum
An isolate of Trichoderma harzianum directly attacked the mycelium of Rhizoctonia solani when the two fungi were grown together on a glucose plus minerals medium. No antibiotic activity of T. harzianum towards the pathogen could be detected. When grown on a mineral medium containing laminarin or chitin as carbon sources, T. harzianum produced the enzymes ,8-(1-3) glucanase and
