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 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.
