Antimicrobial hexapeptides

A method of inhibiting the growth of a fungal cell comprising:

• contacting said fungal cell with an effective amount of a hexapeptide comprising the amino acid sequence given by the formula XBXBOB;
• wherein X is a charged residue, B is a hydrophobic residue, and O is a naphthylalanine, an aliphatic, or an aromatic residue;
• and wherein said fungal cell is a plant pathogen selected from the group consisting of Mycosphaerella brassicicola, Pyrenopeziza brassicae, Peronospora destructor, and Botrytis squamosa.
