This application discloses herbicidal 1-arylpyrazoles, compositions containing them, methods of preparing them, and methods for controlling undesired plant growth by preemergent or postemergent application of the herbicidal compositions to the locus where control is desired. The herbicidal compounds have the following generic structure: ##STR1## in which Ar is ##STR2## R is chlorine, cyano, or nitro; R.sup.1 is a group --C(O)CR.sup.11 R.sup.12 --O--R.sup.13 in which R.sup.11 and R.sup.12 are independently hydrogen or alkyl; R.sup.13 is hydrogen, alkylcarbonyl, phenylcarbonyl, phenylmethyl, or alkylaminosulfonyl; R.sup.2 is hydrogen, alkyl, alkylcarbonyl, alkoxycarbonyl, or a group --C(O)CR.sup.11 R.sup.12 --O--R.sup.13 ; R.sup.3, R.sup.4, R.sup.6, R.sup.7 are independently hydrogen or halogen; R.sup.5 is halogen or haloalkyl; R.sup.8 is halogen; R.sup.9 is haloalkyl; R.sup.10 is hydrogen, halogen, or a group --NR.sup.14 R.sup.15 in which R.sup.14 is hydrogen or alkyl; R.sup.15 is alkyl, alkynyl, or a group --CHR.sup.16 --Ar.sup.1 in which R.sup.16 is hydrogen or alkyl; and Ar.sup.1 is tetrahydrofuran-2-yl; furan-2-yl, thien-2-yl, phenyl, or phenyl substituted with halogen or alkoxy. When R.sup.10 is a group --NR.sup.14 R.sup.15, in addition to the substituents listed above, R.sup.1 may be alkylcarbonyl, haloalkylcarbonyl, or cycloalkylcarbonyl; and R.sup.2 may be hydrogen, alkylcarbonyl, or cycloalkylcarbonyl.
