| abstract |
The present invention relates to new oligopeptides with biological activity, in free form or in salt form, in particular those which have both a modified N-terminal amino acid residue and a modified C-terminal amino acid residue, preferably corresponding pentadecapeptides. The present invention further relates to a method for producing such peptides and their use, biologically active agents whose active ingredient is selected from these peptides, a method for producing such agents and their use, plant propagation material which has been treated with such agents, and a Pest control procedures. |
