FIELD: herbicides, agriculture. SUBSTANCE: invention relates to agents used for control of weeds, in part, to herbicide agent containing 1-(3-chloro-4,5,6,7- tetrahydropyrazolo-[1,5-a]-pyridine-2-yl)-5-(methylpropargylamino)-4-pyrazolylcarboxylic acid nitrile as an active component (A) and additional active component (B) taken among the group including the following substances: bentazon, molinate, daimuron, thiobencarb, butachlor, pretylachlor, dimepiperate, phenoxaprop-ethyl, clomeprop, cinmetilin, bromobutid, chinclorac, mefenacet, pyrazosulfuron-ethyl, esprocarb, cinosulfuron, tenilchlor, cumyluron, MK 243, naproanilide, anilofos, benfuresat, bifenox, CH-900, MCPA, nitrofen, oxadiazon, pendimetalin, simetrin, sulcotrion (ICIA 0051), trifluralin, piperofos, pyributicarb, ethoxy-sulfuron, bensulfuronmethyl, pyrazolat, pyrazoxyfen, benzo-fenap, cyclosulfamuron, cichalofopbutyl, NBA-061 and azimsulfuron. The new developed herbicide agent including 1-(3-chloro-4,5,6,7-tetrahydropyrazolo-[1,5-a]- pyridine-2-yl)-5-(methylpropargylamino)-4-pyrazolylcarboxylic acid nitrile as an active component shows higher activity as compared with that of the nearest analogue. EFFECT: enhanced herbicide activity of agent. 3 cl, 42 ex
