  1-Alkyl-4-benzoyl-5-hydroxy-1H-pyrazole compounds in which the benzoyl moiety is substituted in the 2-position with groups such as halo or alkyl, in the 4-position with an alkylsulfonyl group, and in the 3-position with an acyclic or cyclic derivatized amino group, such as 1-ethyl-4-(2-chloro-4-methylsulfonyl-3-(morpholin-4-yl)benzoyl-5-hydroxy-1 H-pyrazole, were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds can be applied either preemergently or postemergently and can be used to control undesirable vegetation in corn, rice, and wheat crops.
