Embodiment 1

[0023] Formulation Example 1 : 5.1% sulfaflufenacil · acetochlor (0.1:5) emulsion in water

[0024] With 5 grams of DMF, 1 gram of fensulam is completely dissolved and then transferred to the mixing kettle, then 50 grams of acetochlor, 30 grams of phenylphenol polyoxyethylene polyoxypropylene ether and sulfate (or Phosphate), 30 grams of calcium dodecylbenzenesulfonate and 150 grams of xylene, after mixing, add 20 grams of ethylene glycol, 2 grams of xanthan gum, 3 grams of defoamer and 709 grams of pure water, and stir evenly , to obtain a 5.1% sulfaflufenacil-acetochlor aqueous emulsion herbicidal composition.

Embodiment 2

[0025] Formulation Example 2 : 70.5% sulfaflume·metolachlor (0.5:70) microcapsule powder

[0026] With 25 grams of DMF, 5 grams of flumesulam was completely dissolved, and then 700 grams of metolachlor, 40 grams of phenylphenol polyoxyethylene polyoxypropylene ether and its sulfate (or phosphate), 30 grams of ten Calcium dialkylbenzene sulfonate, 200 grams of urea-formaldehyde resin prepolymer and 3 grams of defoamer, mix well, after shearing, slowly add 200 grams of initiator while stirring, slowly stir at 60 ° C for half an hour, and then vacuum freeze-dry , that is, a 70.5% flumesulam·metolachlor microcapsule powder herbicidal composition.

Embodiment 3

[0027] Formulation Example 3 ： 31% sulfaflufenacil·butachlor (1:30) microemulsion

[0028] Dissolve 10 grams of pyrimsulam completely with 90 grams of cyclohexanone and pump it into the mixing tank, then add 100 grams of methanol, 300 grams of butachlor, 40 grams of alkylphenol formaldehyde resin polyoxyethyl ether, 30 grams of alkane Calcium phenyl sulfonate, 40 grams of phenylphenol polyoxyethylene ether, 3 grams of defoamer and 387 grams of purified water were stirred evenly; to obtain a 31% flumesulam·butachlor microemulsion herbicidal composition.

Abstract

The invention relates to a herbicidal combination containing flumetsulam. The herbicidal combination is characterized in that: the active ingredients of the herbicidal combination are component A and component B; the component A is the flumetsulam; and the component B is chosen from one or more of the following compounds: acetochlor, butachlor, alachlor, propisochlor, metolachlor, s-metolachlor, propachlor, ethachlor, napropamide, diphenamide, ethaprochlor, dimethenamid, high-effective dimethenamid, flufenacet, metazachlor, allidochlor, pethoxamid, prynachlor and propyzamide. The herbicidal combination can effectively decrease the dosage of the active ingredients per mu, broaden the weed control spectrum of each single agent and effectively control annual or perennial gramineous, broadleaf and cyperaceous weeds in the fields of peanut, soybean, rape, cotton, wheat, potato and other crops, such as green bristlegrass, crabgrass, barnyard grass, Asian sprangletop, speedwell, cocklebur, night shade, redroot amaranth, goosefoot, Indian mallow, cleavers and datura.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicidal composition containing flumetsulam. Background technique [0002] Flumetsulam, also known as Kuocaoqing, chemical name: 2',6'-difluoro-5-methyl(1,2,4) triazolo(1,5-α) pyrimidine -2-sulfonylanilide, molecular formula C 12 h 9 f 2 N 5 o 2 S, belonging to triazolopyrimidine sulfonamide herbicides, is a typical acetolactate synthase inhibitor. By inhibiting the synthesis of branched-chain amino acids, protein synthesis is blocked, weeds stop growing, and eventually lead to death. [0003] Amide herbicides are a class of herbicides with rapid development and high herbicidal effect. This kind of herbicides develops rapidly. By 2007, the application scope and application area of ​​annual output are second only to organophosphorus herbicides, ranking second in the world. In the international market, the amide herbicides with the largest sales...
