New acylated urea derivatives of the general formula in which mean: X is hydrogen or halogen; Y halogen; R₁, R₂ independently of one another are hydrogen, C₁-C₆-alkyl, C₁-C₆-alkyl substituted with halogen, cyano, C₁-C₄-alkoxy or COO-C₁-C₃-alkyl, C₃-C₅-alkenyl, C₃-C₅ substituted with halogen -Alkenyl, C₃-C₅-alkynyl, C₃-C₅-alkynyl substituted with halogen, C₃-C₇-cycloalkyl, C₃-C₂-alkyl, halogen, cyano or COO-C₁-C₃-alkyl substituted C₃-C₇-cycloalkyl, phenyl , Benzyl, phenyl or benzyl substituted with C₁-C₃-alkyl, C₁-C₃-alkoxy or halogen; and R₁ can also represent the radical Q or Q substituted by C₁-C₃-alkyl, C₃-C₇-cycloalkyl, C₁-C₃-alkoxy or halogen, where Q can be bonded to the N atom via a C₁-C₂-alkyl ; or wherein R₁ and R₂ together with the adjacent N atom form a 3- to 7-membered heterocycle, which additionally contain 1 or 2 further heteroatoms, such as O, N or S, and a carbonyl group and with C₁-C₃-alkyl, halogen or COO-C₁-C₃-alkyl may be substituted; Q furan-2-yl, thiophene-2-yl, isoxazol-3-yl, isoxazol-5-yl, thiazol-2-yl, 1,2,4-thiadiazol-3-yl, 1,3,4-thiadiazole -2-yl, 2-, 3- or 4-pyridyl radicals, 2-, 3- or 4-pyridyl radicals substituted with C₁-C₃-alkyl, C₁-C₃-alkoxy, C₁-C₃-alkylthio or halogen; 2-, 4- or 5-pyrimidyl radicals or 2-, 4- or 5-pyrimidyl radicals substituted with C₁-C₃-alkyl, C₁-C₃-alkoxy, C₁-C₃-alkylthio, halogen or cyclopropyl.n n n The new active ingredients have plant-protecting properties and are particularly suitable for the preventive protection of plants against the infestation of phytopathogenic microorganisms such as fungi, bacteria and viruses. |
