Introduction

Peptides of the natural peptaibol trichogin, derived from Trichoderma fungus, have been patented for the leaf treatment of Plasmopara Viticola (grape downy mildew) and other common agricultural pathogens.

Technical features

Fungi of the genus Trichoderma produce peptaibols, secondary metabolites that are part of their defence system against other microorganisms. Such compounds are known for their ability to protect plants from parasites by stimulating the plant’s defence mechanisms and because of their antimicrobial properties. This patent covers the synthetic analogues of the natural trichogin peptide GA IV and their use as biopesticides against Plasmopara viticola, Botrytis cinerea, Penicillium italicum, Penicillium digitatum, Penicillium expansum, Fusarium graminearum e Pyricularia oryzae. Compared to other peptaibol based products on the market, which are generally non purified natural extracts, this biocompatible product is much more effective, as well as soluble in water and stable in sunlight.

Possible Applications

• Biopesticide for Plasmopara viticola;
• Biopesticide for Botrytis cinerea;
• Biopesticide for Penicillium digitatum and Penicillium expansum;
• Biopesticide for Fusarium graminearum;
• Biopesticide for Pyricularia oryzae.

Advantages

• Soluble in water;
• Biocompatible;
• Pure composition = greater effectiveness;
• Stable under sunlight;
• It is the only existing treatment for downy mildew.
