Novel pyrazole derivatives of formula (I), wherein: X is oxygen or sulfur; R 1 is C1-C3alkyl, C1-C3haloalkyl, C1-C3alkoxy-C1-C3alkyl or C1-C3haloalkoxy-C1- C3alkyl; R2 is C1-C3haloalkyl; and R3 is halogen. The novel compounds have plant-protective properties and are suitable for protecting plants against infestations by phytopathogenic microorganisms.
