The present invention belongs to the field of pesticides, and specifically relates to a herbicidal composition containing an R-type pyridyloxy carboxylic acid derivative and the use thereof. The composition comprises a herbicidally effective amount of active ingredient A and active ingredient B, wherein the active ingredient A is selected from one or more of the R-type pyridyloxy carboxylic acid as shown by formula I, and salt and ester derivatives thereof: (I), wherein, R1 and R2 each independently represent a halogen, a C1-C6 alkyl, a halo C1-C6 alkyl, or a C3-C6 cycloalkyl; R3 represents hydrogen, a halogen, a C1-C6 alkyl, or a halo C1-C6 alkyl; Q represents a C1-C6 alkyl, etc.; and Y represents amino, etc.; and the active ingredient B is selected from one or more of the following compounds and acids/salts/esters thereof: an ALS inhibitor, an ACCase inhibitor, a PSII inhibitor, a HPPD inhibitor, a PDS inhibitor, a DOXP inhibitor, a PPO inhibitor, a synthetic hormone inhibitor, an EPSPS inhibitor, a GS inhibitor, and a PSI inhibitor. The composition can effectively prevent and eliminate various weed problems, and have the characteristics of expanding the weed control spectrum, reducing the application amount, being able to produce synergistic effects, solving weed resistance, etc. |
