The application discloses a kind of herbicidal compositions, the composition includes active ingredient A and active ingredient B, wherein active ingredient A is formula (I) compound, active ingredient B is selected from one or more of pendimethalin, flufenacet and oxaziclomefone.The mass ratio of active ingredient A and active ingredient B of the composition is 1:50-50:1.The component of the application is reasonable, and the activity and herbicidal effect are not simply superimposed of each component, compared with single preparation, with the characteristics of significant herbicidal effect, low drug dosage, broad spectrum of weeds, good crop safety.

The application belongs to the field of pesticides, and particularly relates to an adjuvant combination for preparing a suspension agent, flufenacet water suspension agent and a preparation method thereof, wherein the adjuvant combination comprises, in parts by weight, 5-20 parts of a synergist, 5-15 parts of a wetting dispersant and 1-3 parts of a stabilizer; the synergist is one or a mixture of several of polyether, fatty alcohol ether and organosilicon; the wetting dispersant is one or a combination of any of high-molecular polyacrylate, polycarboxylate and polyester; and the stabilizer is EDTA sodium salt; the adjuvant combination is used for preparing the flufenacet water suspension agent, so that the storage stability and application performance of the preparation are improved, and the effects of reducing the cost of using the pesticide, increasing the effect with a reduced amount and environmental protection are achieved.

The invention relates to the field of herbicides, in particular to a herbicide composition containing pyroxasulfone, thifensulfuron methyl and flufenacet, which is used for solving the problem that the combined action of pyroxasulfone, thifensulfuron methyl and flufenacet is not reported at present. The herbicide composition is prepared by reasonably compounding pyroxasulfone, thifensulfuron methyl and flufenacet, then the herbicide composition is applied to weeds, the herbicide composition is absorbed by the weeds, and the herbicide composition controls the weeds by utilizing three weed control mechanisms of pyroxasulfone, thifensulfuron methyl and flufenacet. Compared with the prior art, the weeding composition has the advantages that the weeding effect is improved, the application amount of pyroxasulfone, thifensulfuron methyl and flufenacet can be reduced, the generation of drug resistance of weeds to the weeding composition is retarded, and the purpose of efficient and long-acting prevention and control is achieved.

The present invention relates to mixtures comprising: i) a first herbicide selected from the group consisting of the Very Long-Chain Fatty Acid inhibitors, preferably dimethenamid, dimethenamid-P or flufenacet; and ii) a second and a third herbicide each independently selected from the group consisting of the Very Long-Chain Fatty Acid inhibitors, preferably dimethenamid, dimethenamid-P or flufenacet, the Acetolactate Synthase inhibitors, preferably thiencarbazone, and the 4-Hydroxyphenylpyruvate Dioxygenase inhibitors, preferably mesotrione; provided that the first, second and third herbicides are different from each other. The invention further relates to formulations containing said mixtures and to a method for controlling weeds.

The invention relates to the technical field of pesticides, in particular to a flufenacet and bensulfuron methyl paddy field herbicide composition as well as a preparation method and application thereof. The herbicide composition comprises flufenacet, bensulfuron methyl, an auxiliary agent and an organic solvent, the method comprises the following steps: obtaining a flufenacet active compound, a bensulfuron methyl active compound and an auxiliary agent, and respectively crushing the flufenacet active compound and the bensulfuron methyl active compound through crushing equipment; adding the weighed flufenacet into the organic solvent, stirring until the flufenacet is dissolved, and adding the weighed bensulfuron methyl; sequentially adding an emulsifier, a dispersant and a stabilizer into the mixture, and stirring and mixing to obtain a mixed material; feeding the mixed material into an ultrafine grinder; adding a proper amount of deionized water into the crushed material, stirring to form a plastic material, and feeding the plastic material into an extrusion granulator for granulation; screening the dried particles through a screening machine; in this way, the effects of being wide in weeding spectrum, remarkable in synergism, safe to rice and afterreap crops and environmentally friendly are achieved.

The invention discloses a weeding composition containing flufenacet and diflufenican, the effective components of the weeding composition comprise an active component A, an active component B and an active component C. The active component A is flufenacet, the active component B is diflufenican, and the active component C is flumetsulam. The weeding composition disclosed by the invention can be used for wheat fields, has an excellent control effect on various annual or perennial weeds in the wheat fields, and is remarkable in synergistic interaction, wide in use period, long in lasting period and safe to afterreap crops.
