- R.sup.e is C.sub.1 -C.sub.4 -alkyl, C.sub.3 -C.sub.4 -alkenyl, C.sub.3 -C.sub.4 -alkynyl or C.sub.3 -C.sub.4 -haloalkenyl;
- R.sup.f is C.sub.1 -C.sub.4 -alkyl which carries one C.sub.1 -C.sub.4 -alkylthio or C.sub.1 -C.sub.4 -alkoxy radical;
- R.sup.g and R.sup.h are hydrogen; and
- R.sup.i is hydrogen or an equivalent of an environmentally compatible cation.
- 2. A herbicidal composition as set forth in claim 1, containing a haloimidazole derivative Ia or Ib and a herbicide of the formula X, the ratio of Ia or Ib:X being from 4:1 to 0.01:1 parts by weight.
- 3. A process for the selective control of unwanted plant growth, wherein a herbicidally/antidotally effective amount of a haloimidazole derivative of the formula Ia or Ib, or Ia and Ib, as set forth in claim 1 and a cyclohexenone derivative of the formula X as set forth in claim 1 are applied--either simultaneously or one after the other--before, during or after the sowing of the crop plants, or before or during emergence of the crop plants.
- 4. A process for preventing damage to crop plants by herbicidal cyclohexenone derivatives of the formula X as set forth in claim 1, wherein the seed of the crop plants is treated with a herbicidally/antidotally effective amount of a haloimidazole derivative of the formula Ia or Ib, or Ia and Ib, as set forth in claim 1.
- 5. A process for the selective control of unwanted plant growth, wherein the leaves of the crop plants and the unwanted plants are treated, either simultaneously or one after the other, with a herbicidally/antidotally effective amount of a haloimidazole derivative of the formula Ia or Ib, or Ia and Ib, as set forth in claim 1 and with a cyclohexenone derivative of the formula X as set forth in claim 1.
- 6. A process as set forth in claim 3, wherein the crop plants are barley, wheat, Indian corn, sorghum and rice.
- 7. A process as set forth in claim 4, wherein the crop plants are barley, wheat, Indian corn, sorghum and rice.
- 8. A process as set forth in claim 5, wherein the crop plants are barley, wheat, Indian corn, sorghum and rice.
- 9. A herbicidal composition as set forth in claim 1, containing a haloimidazole derivative Ia or Ib and a herbicide of the formula X, the ratio of Ia or Ib:X being from 4:1 to 0.25:1 parts by weight.
- 10. A process as in claim 3 wherein the application rate of the herbicidal active ingredient is from 0.001 to 0.5 kg/ha and the ratio of the herbicidal active ingredient to antidote is about 1:4 to 1:0.01.
- 11. A process as in claim 10 wherein the ratio of the herbicidal active ingredient to antidote is about 1:4 to 1:0.25.
