Abstract
The invention relates to a mixed herbicide composition including mesosulfuron-methyl and flumetsulam. The herbicide composition employs mesosulfuron-methyl and flumetsulam as active ingredients, wherein the weight ratio of the active ingredients (flumetsulam : mesosulfuron-methyl) is 1:10-20:1. The herbicide composition has the advantages of low toxicity, weak sensitization, low poison to humans and animals, wide herbicide spectrum and significant synergistic effect for preventing and eradicating weeds, and is particularly suitable for prevention of various weeds in multiple crop fields, especially in wheat fields.
Description
[technical field]
The invention belongs to the pesticide herbicide field, particularly a kind of weed killer herbicide that is used to prevent and treat the wheat paddock weeds, it is by the grand binary herbicidal composition of forming for active component of compound (A) Flumetsulam and compound (B) methyl two sulphurs.
[background technology]
Weeds are one of principal elements of harm Wheat Production, for making improving yield of wheat, must prevent and treat weeds.In recent years, rationally select the wheat paddock weed killer herbicide to become to guarantee the important technical links of wheat safety in production for use, but because drug of choice is improper or operation technique is not in place, control efficiency is undesirable or cause phenomenon such as poisoning to take place repeatedly.The weed killer herbicide kind that can prevent and kill off grassy weed and broad leaved weed at present simultaneously seldom; Generally people use certain weed killer herbicide to prevent and kill off after the grassy weed, and broad leaved weed becomes the dominant population of weeds again, or prevent and kill off after the broad leaved weed; Grassy weed becomes the dominant population of weeds again; Therefore certainly will require the medication of people's repeated multiple times to prevent and kill off all kinds of weeds, waste great amount of manpower and material resources like this, on the other hand; Cause agricultural chemicals to the pollution of environment and exceeding standard of food residue of pesticide, human health is brought direct harm.
Flumetsulam is a kind of typical acetolactate synthestase (ALS) inhibitor.Because its serious inhibitory action stops the interior branched-chain amino acid-leucine of plant corpus, valine and isoleucine biosynthesis, protein synthesis is obstructed, and growth retardation is final dead.Methyl two sulphurs are grand to be interior absorption translocated herbicide, can be absorbed rapidly by weeds cauline leaf and root, conducts rapidly at phloem and xylem subsequently; Through suppressing the biosynthesis of side chain amino acid in the plant corpus; Cause the sensitive plant growth retardation, the cauline leaf chlorisis, withered gradually.Exist bigger limitation on careless spectrum, preventive effect, safety, the cost killing when above weed killer herbicide uses as single agent, therefore, need composite use reach synergy, reduce consumption, enlarge the purpose of killing the grass spectrum.
[summary of the invention]
Technical problem to be solved by this invention is, to the deficiency that prior art exists, a kind of technical scheme of Compositional herbicide for cornfield composition is provided, and kills the grass spectrum with what enlarge cornfield herbicidal, reduces the medicament usage amount and to the poisoning of wheat.
The technical scheme that the present invention adopts is; Swelling with compound (A) Flumetsulam and compound (B) methyl two sulphurs is active ingredient; Be aided with solvent, carrier, surfactant and other auxiliary agents and be prepared into any formulation that agricultural goes up permission, wherein most preferred dosage form is a water dispersible granules.
Said active ingredient is compound (A) Flumetsulam (Flumetsulam), other title: Flumetsulam, beans grass ability, and chemical name: 2,6-two fluoro-5-methyl [1,2,4] triazol [1,5-a] pyrimidine-2-sulfonanilides, structural formula is:
Compound (B) methyl two sulphurs swell (Mesosulfuron-methyl), other titles: mesosulfuronmethyl, generation agate, and chemical name: N-[(4,6-dimethoxypyridin-2-yl) aminocarbonyl]-2-methoxycarbonyl group-5-mesyl aminomethyl phenyl sulfonamide, structural formula is:
The weight ratio of said herbicidal composition effective ingredient is compound (A) flumetsulam amines: (B) methyl two sulphurs swell=1: 10～20: 1, are preferably 1: 4～10: 1, are more preferably 16: 9.
The weight percentage of said active ingredient in herbicidal composition is 0.5～85%.
Said solvent comprises one or more mixtures in water, benzene,toluene,xylene, methyl alcohol, ethanol, isopropyl alcohol, butanols, line oil, cyclohexanone, acetonitrile, carrene, chloroform, dimethyl formamide, dioxane, naphthalene, methyl naphthalene, dimethyl sulfoxide (DMSO), N-Methyl pyrrolidone, ethyl acetate, acetone, butanone, ether, the gylcol ether; Carrier comprises one or more mixtures in kaolin, bentonite, atlapulgite, sepiolite, white carbon, diatomite, lightweight calcium silicates, talcum powder, the plaster of paris, chalky soil, potter's clay, imvite, the clay; Surfactant comprises one or more mixtures in anion, cation, the nonionic surface active agent; Other auxiliary agent comprises one or more mixtures in urea, polyvinyl alcohol, polyvinylpyrrolidone, carboxymethyl cellulose, xanthans, gum Arabic, gelatin, starch, alginic acid, ethylene glycol, propane diols, glycerine, octanol, the silicone.
Herbicidal compositions according to the invention are mainly used in wheat Tanaka control weeds such as foxtail, wild oats, hard grass, bluegrass, Polypogon grass, Wang grass, brome, plants, candles, grass, Puccinellia, sowing sophia, cattle chickweed, shepherd's purse, velvetleaf, pigweed, cleavers, Mandala, Amaranthus, fragrant chamomile, wild radish, tattoo Nim, Polygonum, Kochia, black nightshade, wild sesame, speedwell , wild watermelon seedlings, cocklebur, wind cauliflower, Thlaspi arvense, green foxtail, wild water chestnuts, etc., but not limited to the above weeds.
The present invention possesses following beneficial effect:
In the herbicidal composition of the present invention, each active component is composite in certain ratio range, shows good synergistic effect; The more single agent of mixed composition has obviously improved herbicidal effect; And then reduced using dosage, when reducing drug cost, reduced influence degree to environment.
Enlarged herbicidal spectrum; This herbicidal composition adopts Flumetsulam and the grand use that is mixed of methyl two sulphurs; Because this two components mechanism of action is different; Make a kind of medicament can prevent and treat wheat paddock broad leaved weed and grassy weed simultaneously, and can prolong the preventive effect phase that a dispenser can be controlled the weeds in the wheat paddock whole growing.
In addition, Herbicidal combinations low toxicity of the present invention, low to crop, toxicity to man and livestock, can under the situation that does not injure crop, kill and remove multiple weeds, delay the drug-fast generation of weeds, improve total preventive effect, and reduced application cost, safer to crop.
