Novel acylated urea derivatives of the general formula <IMAGE> in which: X is hydrogen or halogen; Y is halogen; R1, R2 independently of one another are hydrogen, C1-C6alkyl or C1-C6alkyl which is substituted by halogen, cyano, C1-C4alkoxy or COO-C1-C3alkyl, or is C3-C5alkenyl or C3-C5alkenyl which is substituted by halogen, or is C3-C5alkynyl or C3-C5alkynyl which is substituted by halogen, or is C3-C7cycloalkyl or C3-C7cycloalkyl which is substituted by C1-C2alkyl, halogen, cyano or COO-C1-C3alkyl, or is phenyl, benzyl or phenyl or benzyl which are substituted by C1-C3alkyl, C1-C3alkoxy or halogen; and R1 can furthermore also be the radical Q or Q which is substituted by C1-C3alkyl, C3-C7cycloalkyl, C1-C3alkoxy or halogen, where Q can be bonded to the N atom via a C1-C2alkyl; or where R1 and R2 together with the adjacent N atom from a 3- to 7-membered heterocycle which can additionally contain 1 or 2 further hetero atoms such as O, N or S, and a carbonyl group and can be substituted by C1-C3alkyl, halogen or COO-C1-C3alkyl; Q is furan-2-yl, thiophen-2-yl, isoxazol-3-yl, isoxazol-3-yl, thiazol-2-yl, 1,2,4-thiadiazol-3-yl, 1,3,4-thiadiazol-2-yl, 2-, 3- or 4-pyridyl radicals or 2-, 3- or 4-pyridyl radicals which are substituted by C1-C3alkyl, C1-C3alkoxy, C1-C3alkylthio or halogen; 2-, 4- or 5-pyrimidyl radicals or 2-, 4- or 5-pyrimidyl radicals which are substituted by C1-C3alkyl, C1-C3alkoxy, C1-C3alkylthio, halogen or cyclopropyl. The novel active substances have plant-protecting properties and are suitable in particular for the preventive protection of plants against infection with phytopathogenic microorganisms, such as fungi, bacteria and viruses. |
