The invention relates to 4-benzoylisoxazoles having the formula: ##STR1## wherein: R is hydrogen or --CO.sub.2 R.sup.5 ; R.sup.1 is alkyl, cyclopropyl or 1-methylcyclopropyl; R.sup.2 is chlorine, bromine, optionally substituted alkyl, alkoxy, haloalkoxy, --S(O).sub.p R.sup.61, nitro or cyano; R.sup.3 is --S(O).sub.n R.sup.6 ; R.sup.4 is hydrogen, fluorine, chlorine, bromine, optionally substituted alkyl, alkoxy, S(O).sub.q R.sup.61, nitro, cyano or --CO.sub.2 R.sup.52 ; R.sup.5 and R.sup.61, which are the same or different, are each alkyl or haloalkyl; R.sup.52 is alkyl; R.sup.6 is alkyl, alkenyl or alkynyl optionally substituted by one or more halogen; and n, p and q, which are the same or different, are each zero, one or two; and their use as herbicides.

4-benzoyl isoxazoles and their use as herbicides

Herbicides derived from 2-cyano-1,3-diones have the formula: ##STR1## wherein R, R.sup.1, R.sup.2 R.sup.3, R.sup.4 and R.sup.5 are as defined in the description. The compounds are intended for use pre- and post-emergence as selective herbicides in maize and a large number of other monocotyledon crops.
