Abstract
The invention relates to new peptides and their use as pesticides. In particular, these peptides have been advantageously used for the treatment of vine peronospora (downy mildew).
Claims10
A method of protecting plants against phytopathogenic organisms, said method comprising treating said plants with a peptide or of its salt, said peptide having the sequence
- 1-octanoyl-Aib-X-Lys(HCl)-Leu-Y-Z
- wherein:
- X is selected from the group consisting of:
- -Gly-Leu-Aib-Lys(HCl)—;
- -Gly-Leu-Aib-Gly-;
- and
- -Lys(HCl)—;
- or X is missing
- Y is the group:
- -Aib-Gly-Ile- or Y is missing
- and
- Z is selected from the group consisting of:
- -Lol;
- Leu-NH2;
- and
- -Aib-Lys(HCl)-Gly-Leu-Aib-Gly-Ile-Lol, and
- protecting said plants from said phytopathogenic organisms as a pesticide.
