Disclosed are selected 5-amido-3-trihalomethyl-1,2,4-thiadiazole compounds of the formula: ##STR1## wherein R.sub.1 is CCl.sub.3 or CF.sub.3 ; R.sub.2 is hydrogen, a lower alkyl group of 1 to 4 carbon atoms or an aryl group having 6 to 8 carbon atoms; and R.sub.3 is a lower alkyl group having from 2 to 4 carbon atoms, an aryl group having 6 to 8 carbon atoms, or CX.sub.3, where X is H, Cl, F or OCH.sub.3. These compounds are shown to have post-emergence herbicidal properties.
