ABSTRACT:
Novel acylated urea derivatives of the general formula ##STR1## in which: X is hydrogen or halogen; Y is halogen; R.sub.1, R.sub.2 independently of one another are hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.6 alkyl which is substituted by halogen, cyano, C.sub.1 -C.sub.4 alkoxy or COO-C.sub.1 -C.sub.3 alkyl, or is C.sub.3 -C.sub.5 alkenyl or C.sub.3 -C.sub.5 alkenyl which is substituted by halogen, or is C.sub.3 -C.sub.5 alkynyl or C.sub.3 -C.sub.5 alkynyl which is substituted by halogen, or is C.sub.3 -C.sub.7 cycloalkyl or C.sub.3 -C.sub.7 cycloalkyl which is substituted by C.sub.1 -C.sub.2 alkyl, halogen, cyano or COO-C.sub.1 -C.sub.3 alkyl, or is phenyl, benzyl or phenyl or benzyl which are substituted by C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy or halogen; and R.sub.1 can furthermore also be the radical Q or Q which is substituted by C.sub.1 -C.sub.3 alkyl, C.sub.3 -C.sub.7 cycloalkyl, C.sub.1 -C.sub.3 alkoxy or halogen, where Q can be bonded to the N atom via a C.sub.1 -C.sub.2 alkyl; or where R.sub.1 and R.sub.2 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 C.sub.1 -C.sub.3 alkyl, halogen or COO-C.sub.1 -C.sub.3 alkyl; 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 C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, C.sub.1 -C.sub.3 alkylthio or halogen; 2-, 4- or 5-pyrimidyl radicals or 2-, 4- or 5-pyrimidyl radicals which are substituted by C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, C.sub.1 -C.sub.3 alkylthio, 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.
