Strain of Trichoderma harzianum, process for its isolation, process for its culture, peptides or compounds produced by this strain and application of this strain and these peptides or the product produced by the culture process as a means for biological control in the form of a phytosanitary product

摘要

This new strain is deposited at the Pasteur Institute under No. 1223 and at the ATCC under No. 20672. It has been isolated by a cloning technique from Trichoderma harzianum fungi from a moist soil such as a market gardening soil or a cultivated soil. This new strain and the peptides which it produces, called Trichorzianines are employed as a means of biological control in particular for the treatment of the grey rot of vines or the silver leaf disease of fruit trees.
