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.
