- R.sub.1 is dichloromethyl, together with an inert agriculturally acceptable carrier and a surfactant.
- 2. The seed of sorghum which has been treated with a composition according to claim 1.
- 3. A composition according to claim 1, wherein Q is C.sub.1 -C.sub.6 -alkyl.
- 4. A composition according to claim 1, wherein n is 1 or 2.
- 5. A composition according to claim 1, wherein the group QX is methoxy.
- 6. A composition according to claim 1 wherein X is oxygen, Q is methyl, n is 1 or 2, A is C.sub.1 -C.sub.2 -alkylene, B is C.sub.1 -C.sub.4 -alkyl.

- 8. As a wettable powder a composition according to claim 1 comprising from 0.5 to 90% by weight acylamide derivative, 5 to 95% by weight inert solid carrier, and 0.5 to 20% by weight surfactant.
- 9. A composition according to claim 8 comprising 1 to 80% by weight acylamide derivative, 15 to 90% carrier and 1 to 15% by weight surfactant.
- 10. As an emulsifiable concentrate a composition according to claim 1 comprising 1 to 20% by weight acylamide derivative, 5 to 30% by weight surfactant and 50 to 94% by weight inert liquid carrier.
- 11. A composition according to claim 10 comprising 5 to 10% by weight acylamide derivative, 10 to 20% by weight surfactant and 70 to 85% by weight carrier.
- 12. A composition according to claim 1 wherein B is C.sub.1 -C.sub.6 alkyl or C.sub.2 -C.sub.6 alkenyl.
- 13. A composition for selectively controlling weeds in cultures of maize and sorghum, which contains a herbicidally active amount of N-chloroacetyl-N-(2-methoxy-1-methylethyl)-2-ethyl-6-methylaniline and a herbicidally antagonistically effective amount of an acylamide derivative of the formula ##STR19## wherein X is oxygen, Q is C.sub.1 -C.sub.4 -alkyl or C.sub.2 -C.sub.4 -alkoxyalkyl, n is 1 or 2, A is a C.sub.1 -C.sub.4 -alkylene or C.sub.2 -C.sub.4 -alkenylene bridge, z is hydrogen, B is C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkenyl which is unsubstituted or substituted by C.sub.1 -C.sub.4 -alkoxy and R.sub.1 is dichloromethyl, together with an inert agriculturally acceptable carrier and a surfactant.
