Derivatives of N-phenylpyrazoles

N-Phenylpyrazole derivatives of the formula: ##STR1## wherein R.sup.1 represents cyano, nitro, halogen, acetyl or formyl; R.sup.2 represents R.sup.5 SO.sub.2, R.sup.5 SO or R.sup.5 S in which R.sup.5 is optionally halogen substituted alkyl, alkenyl or alkynyl; R.sup.3 represents a hydrogen atom or a group NR.sup.6 R.sup.7 wherein R.sup.6 and R.sup.7 each represent hydrogen, alkyl, alkenylalkyl, alkynylalkyl, formyl, optionally halogen substituted alkanoyl, optionally halogen substituted alkoxycarbonyl, or alkoxymethyleneamino, halogen, or R.sup.6 and R.sup.7 together form a cyclic imide and R.sup.4 represents a substituted phenyl group possess arthropodicidal, plant nematocidal, anthelmintic and anti-protozoal properties; their preparation, compositions containing them and their use are described.
