  • Patent number: 6753339
    Abstract: The invention concerns fungicide compositions comprising a compound (I) which is (4-S)-4-mehtyl-2-methylthio-4-phenyl-1-phenylamino-2-imidazoline-5-one and a compound (II) which is N1-[(R)-1-(6-fluoro-2-benzothiazolyl)ethyl]-N2-isopropoxycarbonyl-L-validamide or isopropyl[2-methyl-1-(phenylethyl-carbamoyl)propyl]carbamate; the compound (I)/compound (II) ratio ranges between 10 and 0.01, preferably between 5 and 0.5. The invention also concerns a method for eradicating or preventing phytopathogenic fungi in crops, characterized in that it consists in applying on the aerial parts of plants an efficient and non-phytotoxic amount of one of said fungicide compositions.
