PHENYL ETHER DERIVATIVES AS MICROBICIDE, MANUFACTURE AND USE

There are described novel phenyl ether derivatives of the formula I where X represents a five- or six-membered unsaturated heterocyclic radical which has one, two or three hetero atoms and which can be unsubstituted or mono-, di- or trisubstituted by halogen, nitro, C1-C3-alkyl, C1-C3-alkoxy, C1-C3-haloalkoxy or trifluoromethyl, R1 represents hydrogen, halogen, C1-C3-alkyl or C1-C3-haloalkoxy and U and V independently of one another represent C1-C12-alkyl which is optionally substituted by halogen or C1-C6-alkoxy, or together form the following alkylene bridges where R2 and R3 independently of one another represent hydrogen, C1-C6-alkyl, C1-C6-alkyl which is monosubstituted or polysubstituted by halogen, or represent phenyl, phenyl which is monosubstituted or polysubstituted by halogen and/or C1-C2-alkyl, or represent the group -CH2-Z-R7, and in which R2 and R3 together form a tetramethylene bridge which is unsubstituted or substituted by C1-C4-alkyl; and where Z represents oxygen or sulphur; R7 represents hydrogen, C1-C6-alkyl, C1-C6-alkyl which is monosubstituted or polysubstituted by halogen or C1-C3-alkoxy, or represents C3-C4-alkenyl, 2-propynyl, 3-halo-2-propynyl, and also phenyl or benzyl whose aromatic ring is unsubstituted or monosubstituted or polysubstituted by halogen, C1-C3-alkyl, C1-C3-alkoxy, nitro and/or CF3; R4, R5 and R6 independently of one another represent hydrogen or C1-C4-alkyl, where the total of the carbon atoms in R4, R5 and R6 does not exceed the number 6; including their acid addition salts and metal complexes. There is furthermore described the preparation of these substances, and agrochemicals which contain one of these compounds as active substance. The preparation of these compositions and their application is described. They can be employed for controlling phytopathogenic microorganisms.
