An N-(2-fluoro-4-halo-5-substituted phenyl)hydantoin of the formula:
- ##STR26## wherein X is a chlorine atom or a bromine atom and R.sup.1 and R.sup.2 are the same or different, and each is a C.sub.1 -C.sub.4 alkyl group, a cyclopropyl group, a C.sub.3 -C.sub.4 alkenyl group or a C.sub.3 -C.sub.4 alkynyl group.
3-(4-Chloro-2-fluoro-5-isopropoxyphenyl)- 1-isopropylimidazolidine-2,4-dione.
3-(4-Chloro-2-fluoro-5-isopropoxyphenyl)-1-ethylimidazolidine-2,4-dione.
A method for controlling weeds which comprises applying as an active ingredient a herbicidally effective amount of the compound of the formula:
- ##STR27## wherein X is a chlorine atom or a bromine atom and R.sup.1 and R.sup.2 are the same or different, and each is a C.sub.1 -C.sub.4 alkyl group, a cyclopropyl group, a C.sub.3 -C.sub.4 alkenyl group or a C.sub.3 -C.sub.4 alkynyl group to the area where the weeds grow or will grow.
