N-Higher aliphatic amino acids, lowe-alkyl esters thereof and their salts are useful for controlling numerous plant diseases. They exhibit excellent protective effect rather than curative effect and have no phytotoxicity, extremely low mammalian toxicity and cause no risk of pollution toward soils.
Claims7
A method of protecting plants from attack by plant disease fungi or bacteria which comprises applying onto a fungus-susceptible plant a fungicidal amount of a compound selected from the group consisting of an N-acyl derivative of a neutral amino acid wherein said acyl moiety is selected from the group consisting of decanoic acid, lauric acid, palmitic acid, stearic acid, oleic acid, linolenic acid, coconut oil fatty acid, myristic acid, capric acid and undecylenic acid and said neutral amino acid is selected from the group consisting of glycine, phenylglycine, alanine, .alpha.-aminobutyric acid, valine, norvaline, leucine, isoleucine, norleucine, phenylalanine, p-nitrophenylalanine, tryptophane, proline, methionine, threonine and sarcosine or the lithium, sodium, potassium or ammonium salts of said N-acyl derivative of a neutral amino acid.
