Abstract

The invention describes novel 1-aryl-5-(substituted alkylideneimino)pyrazoles of formula (I) ##STR1## wherein typically preferred substituents are: R.sup.1 is cyano, nitro, or halogen; PA0 R.sup.2 is R.sup.9 S(O).sub.n in which n is 0, 1 or 2 and R.sup.9 is alkyl, preferably methyl which is substituted by halogen atoms which are the same or different up to full substitution of the alkyl moiety; PA0 R.sup.3 is hydrogen or alkyl; PA0 R.sup.4 is phenyl or heteroaryl, optionally substituted by one or more hydroxy, halogen, alkoxy, alkylthio, cyano or alkyl or combinations thereof; preferably R.sup.4 is phenyl, which is at least substituted by 3-hydroxy or 4-hydroxy; PA0 R.sup.5 is hydrogen, alkyl or halogen; PA0 R.sup.6 and R.sup.8 are hydrogen; PA0 R.sup.7 is halogen, alkyl, haloalkyl or haloalkoxy; and PA0 X is a nitrogen atom or CR.sup.14 in which R.sup.14 is hydrogen, halogen, cyano, alkyl, alkylthio or alkoxy. The invention further describes processes to make the compounds, compositions of the compounds, and methods of use of the compounds for the control of arthropods (mites, aphids or insects), nematodes, helminths, or protozoa.
