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.
本发明涉及公式为:##STR1##其中R.sub.1为CCl.sub.3或CF.sub.3;R.sub.2为氢、1至4个碳原子的低级烷基或具有6至8个碳原子的芳基基团;R.sub.3为具有2至4个碳原子的低级烷基、具有6至8个碳原子的芳基基团或CX.sub.3,其中X为H、Cl、F或OCH.sub.3的选定的5-酰胺-3-三卤甲基-1,2,4-噻二唑化合物。这些化合物被证明具有后出苗除草剂特性。
