Claims35
A method for controlling the growth of weeds at a locus, said method comprising applying to said locus a synergistic herbicidally effective amount of:
- (a) a 4-benzoylisoxazole having the formula I:
- ##STR5## wherein:
- R is hydrogen or --CO.sub.2 R.sup.3 ;
- R.sup.1 is cyclopropyl;
- R.sup.2 is halogen, --S(O).sub.p CH.sub.3, C.sub.1-6 alkyl or C.sub.1-6 haloalkyl;
- n is two or three;
- p is zero, one or two;
- and
- R.sup.3 is C.sub.1-4 alkyl;
- and
- (b) a triazine herbicide;
- the ratio by weight of (a):(b) being from 2:1 to 1:1000.
