Based on the carbamoyl triazole herbicide Cafenstrole, 12 novel selenium-containing compoundswere designed and synthesized. All of the compounds were characterized and confirmed by IR, 1HNMR, and high-resolution mass spectroscopy. The bioassay tests showed that some of the compounds(C2, C4, C7-8, and C12) exhibited good inhibitory activity against cucumber (Cucumis sativus L.) andsemen euphorbiae (Leptochloa chinensis N.). Especially, compound C6 inhibited the growth ofcucumber and semen euphorbiae by >90% at a concentration of 1.875 
g/mL, and the inhibition ofthe compound on the rice (Oryza sativa L.) was only 8.3% at a concentration of 7.5 g/mL, whichindicated a higher selectivity between weed and rice than that shown by Cafenstrole.
