Claims
- 1. A herbicidal composition which comprises a compound of the formula ##STR9## wherein X is a hydrogen atom, a halogen atom, a trifluoromethyl group, or a (C.sub.1 -C.sub.4) alkyl group,
- Y is a hydrogen atom, a halogen atom, or a trifluoromethyl group, and
- Z is an unsubstituted amino group, an amino group having one or both hydrogen atoms replaced by one or two unsubstituted or halo-, hydroxy- or alkoxy-substituted alkyl groups having a total of up to 6 carbon atoms and an agronomically-acceptable carrier.
- 2. A composition according to claim 1 which also comprises a surfactant.
- 3. A method of controlling weeds which comprises applying to the surface of the growth medium prior to the emergence of the weeds from the growth medium a compound according to claim 1 in an amount sufficient to control the growth of the weeds.
- 4. The method of claim 3 wherein the compound is applied at a rate of about 0.1 to about 12 pounds per acre.
- 5. A method of controlling weeds which comprises applying to weed seedlings a compound of the formula ##STR10## wherein X is a hydrogen atom, a halogen atom, a trifluoromethyl group, or a (C.sub.1 -C.sub.4) alkyl group,

- 15. The method according to claim 4 wherein X is a chlorine atom and Z is a hydroxyethylamino group.
- 16. The method according to claim 12 wherein X is a chlorine atom and Z is a hydroxymethylethylamino group.
- 17. The method according to claim 12 wherein X is a chlorine atom and Z is a hydroxyethylethylamino group.
