Novel pyraole derivatives of formula (I), wherein: X is oxygen or sufu, R 1 is C 1 –C 3 alkyl, C 1 –C 3 haloalkyl, C 1 –C 3 alkoxy-C 1 –C 3 alkyl or C 1 –C 3 haloalkoxy-C 1 –C 3 alkyl; R 2 is C 1 –C 3 haloalkyl; and R 3 is halogen. The novel compounds have plant-protective properties and are suitable for protecting plants against infestations by phytopathogenic microorganisms. |
