Abstract

The invention describes novel 1-aryl-5-(substituted alkyl (thio)amido)pyrazoles wherein preferred compounds are of the formula ##STR1## wherein: R.sup.2 is R.sup.11 S(O).sub.n in which n is 0, 1 or 2 and R.sup.11 is alkyl, preferably methyl; or haloalkyl, preferably trihalomethyl or dihalomethyl; and in which halo is F, Cl or Br or combinations thereof and most preferably CF.sub.3, CCl.sub.3, CF.sub.2 Cl, CFCl.sub.2, CF.sub.2 Br, CHF.sub.2, CHClF or CHCl.sub.2 ; PA0 R.sub.4 is H or alkyl; PA0 R.sub.5 is H or alkyl; PA0 R.sup.4 and R.sup.5 could be together to form a 3-7 membered cyclic ring system; PA0 R.sup.6 is alkoxy, alkoxy(alkoxy).sub.b [b=1-2], alkoxy(alkoxy).sub.b alkyl [b=0-2], alkylS(O).sub.c (c=0, 1, 2), alkylS(O).sub.c alkyl [c=0, 1, 2], alkylC(O)--; phenoxy, phenyl S(O).sub.c, phenylalkoxy, pyridyloxy, pyridyl S(O).sub.c, optionally substituted with alkyl, halogen, alkoxy, haloalkyl, haloalkoxy, nitro, cyano, alkylthio. PA0 R.sup.5 and R.sup.6 could be together to form a 4-7 membered cyclic ring with 1-2 heteroatoms (e.g. O, S, S(O), S(O).sub.2, NH, N-alkyl); PA0 R.sup.7 is: hydrogen; alkyl, preferably methyl; or halogen, preferably F, Cl or Br; R.sup.9 is: halogen, pre…
