CUTIN COMPOSITIONS FOR TREATMENT OF PLANT DISEASE
WO2024227954
The invention relates to a composition comprising isolated cutin polymer and/or cutin oligomers for use in prevention or treatment of plant disease, and to a method for prevention or treatment of plant disease, comprising contacting the aerial parts of a plant, particularly leaves and fruit of a plant, with a composition comprising a cutin product consisting of isolated cutin polymer and/or an oligomeric hydrolyzation product of a cutin polymer.
Formulations of plant immune elicitors exists, for example synthetic elicitors (US9622472B2) or derived from yeast extracts (US8609084B2), but none focusing on plant polyesters-derived molecules. At this stage, no open-information on their development and commercialisation status exists. The competitive advantages of our immunostimulatory preparations are: - The bioactive compounds are obtained from agro-residues, hence following a circular economy approach; - The bioactive compounds are prepared using green processes; - The immunostimulatory response of these class of bioactives is distinctive from all known plant immune elicitors; - The formulations can be designed to contain distinct classes of bioactive molecules, some acting as immune elicitors and others as antimicrobial agents. Our solution fits on the market sector of Agricultural Biologicals, which includes bio-stimulants and biopesticides.
