Problems solved by technology

[0006] Dimethyl tetrachloride, 2,4-D butyl ester, dicamba, bromoxynil, rimsulfuron-methyl, bensulfuron-methyl, sulfafenacil, oxyflufen, and florasulam can control wheat fields Most broadleaf weeds, but ineffective against grasses
[0007] Each of the above herbicides has its own unique herbicide spectrum and weeds that cannot be controlled, and the weed control effect is not very ideal when used alone
