The invention provides a compound herbicide composition. The compound herbicide composition comprises a first active ingredient, a second active ingredient and a third active ingredient, wherein the first active ingredient is penoxsulam; the second active ingredient is carfentrazone-ethyl; the third active ingredient is pyrazosulfuron-ethyl; and the weight percent ratio of the three active ingredients is (0.1-20):(0.1-20):(0.1-20). By carrying out ternary compounding on penoxsulam, carfentrazone-ethyl and pyrazosulfuron-ethyl, the obtained new composition has beneficial effects on control of weeds in rice fields, reduces the application dosage of active compounds, expands the weed-controlling spectrum and does not increase the phytotoxicity to crops unacceptably. |
