Claims
- 1. A thiadiazole derivative represented by the formula [IV] ##STR120## wherein R.sup.24 and R.sup.25, which may be the same or different, represent hydrogen or halogen;
- R.sup.26 and R.sup.27, which may be the same or different, represent hydrogen, lower alkyl, --COR.sup.28 where R.sup.28 represents lower alkyl or amino group which may be substituted with lower alkyl, or R.sup.26 and R.sup.27 together form phthaloyl group,
- provided R.sup.24, R.sup.25, R.sup.26, and R.sup.27 are not simultaneously hydrogen atoms and excluding 3-amino-4-(p-bromophenyl)-1,2,5-thiadiazole.
- 2. A herbicidal composition comprising together with an agriculturally acceptable carrier a herbicidally effective amount of a thiadiazole derivative represented by the formula [IV] ##STR121## wherein R.sup.24 and R.sup.25, which may be the same or different, represent hydrogen or halogen;
- R.sup.26 and R.sup.27, which may be the same or different, represent hydrogen, lower alkyl, --COR.sup.28 where R.sup.28 represents lower alkyl or amino group which may be substituted with lower alkyl, or R.sup.26 and R.sup.27 together form phthaloyl group,
- provided R.sup.24, R.sup.25, R.sup.26, and R.sup.27 are not simultaneously hydrogen atoms.
