【Abstract】 Ten new substituted carbamylurea derivatives were synthesized by the reaction of N,N- dialkylurea and N-substituted trichloroacetanilide and their structures were confirmed by elemental analysis, IR, and 1H NMR. The preliminary biological activity test showed that most of them had obvious inhibitory activity for plant growth.更多还原
