Abstract
The invention relates to oligopeptides used as elicitors of the natural defences of plants in order to control fungal and/or bacterial and/or viral pathogens and/or crop pests, by means of foliar or root application or by injection. According to the invention, said oligopeptides are characterised in that they are obtained by organic or enzymatic synthesis, in that they are heteropolymers and/or homopolymers of protein and/or non-protein amino acids, and in that said amino acids form sequences of said polymers selected for the capacity thereof to form spiral structures.
Claims8
Oligopeptides used as elicitors of the natural defenses of plants against fungal and/or bacterial and/or viral pathogens and/or plant pests by foliage, root or injection application;
- characterized in that they are obtained by organic or enzymatic synthesis;
- and that they have the particularity of being homopolymers of protein and/or non-protein amino acids and in that the amino acids constitute sequences of said polymers which are selected for their property to form structures of the spiral type.
Composition characterized in that it comprises at least one oligopeptide obtained according to at least one of the preceding claims and comprising at least one amino acid of the protein and/or non-protein type.
