Abstract
The invention belongs to the technical field of pesticides and relates to a herbicidal composition containing flumetsulam and monosulfuron ester. The herbicidal composition contains the flumetsulam and the monosulfuron ester in a weight ratio of (50 to 1)-(1 to 10), wherein the total weight percentage of active components is 3-80% and the balance is auxiliary components which are permitted to use and can be accepted in pesticides. The flumetsulam and the monosulfuron ester compounded in a certain proportion have an obvious synergic effect and the herbicidal composition has a relatively good preventive effect when being applied to preventing and treating broadleaf weeds such as field horsetail (hippochaete ramosissmum), shepherd's purse, Erysimum cheiranthoides Linn., garden cress, flixweed, polygonum, procumbent speedwell, xanthium sibiricum, nightshade, amaranthus retroflexus, chenopodium album, piemarker (fruit), cleavers, and darura stramonium linn.
Description
Technical field
The invention belongs to technical field of pesticide, relate to pesticide combination technology, particularly the compounded technology of Flumetsulam and single phonetic sulphur ester.
Background technology
Flumetsulam
Chemical name: N-(2,6-difluorophenyl)-5-methyl isophthalic acid, 2,4-triazol [1,5-a] pyrimidine-2-sulfonamide; Flumetsulam; The fluoro-5-methyl of 2', 6'-bis-(1,2,4)-triazol (1,5-a) pyrimidine-2-sulfonanilide
Flumetsulam molecular formula: C12H9F2N5O2S
Relative molecular weight: 325.294
Structural formula:
This medicine belongs to triazolopyrimidine sulfonamides, is typical inhibitor of acetolactate synthetase.By suppressing the synthesis of branched-chain amino acid to make protein biosynthesis block, plant stops growing.Longevity of residure length, broad weed-killing spectrum, soil, cauline leaf process.
Single phonetic sulphur ester
Chemical name: 2-methyl formate-N-[2-(4-methylpyrimidine base)] benzene sulfonylurea
Single Mi Huangzhishi Nankai University formulates successfully another novel herbicide kind after sulfonylurea weed killer herbicide monosulfmeturon.Compared with current main cornfield herbicidal, the little super-high-efficient of single phonetic sulphur ester amount of having, environmental friendliness, the feature that application cost is moderate.Single phonetic sulphur ester formulation every mu of effective ingredient consumption only needs 1.5 grams, and effectively can prevent and kill off the broad leaved weeds such as wheatland main weeds Descurainia sophia, shepherd's purse, lamb's-quarters, activity of weeding is high, and average control efficiency reaches 96.7%.
But composition composite with single phonetic sulphur ester for Flumetsulam is not also had relevant report.
Summary of the invention
The object of the present invention is to provide a kind of high-efficiency broad spectrum Herbicidal combinations based on Flumetsulam.
The object of the present invention is achieved like this, based on the characteristic research of Flumetsulam, adopts single phonetic sulphur ester as composite component, produce obvious synergistic effect, and expanding prevention spectrum.
For achieving the above object, the technical solution used in the present invention is as follows:
Flumetsulam and a Herbicidal combinations for single phonetic sulphur ester, form for active ingredient is composite with Flumetsulam and single phonetic sulphur ester, Flumetsulam is 50:1 ~ 1:10 with the weight ratio of single phonetic sulphur ester.
Preferably, described Flumetsulam and the Herbicidal combinations of single phonetic sulphur ester, form for active ingredient is composite with Flumetsulam and single phonetic sulphur ester, Flumetsulam is 15:1 ~ 1:1 with the weight ratio of single phonetic sulphur ester.
The Herbicidal combinations of described Flumetsulam and single phonetic sulphur ester, form for active ingredient is composite with Flumetsulam and single phonetic sulphur ester, active ingredient weight percent content is 3 ~ 80%.
The Herbicidal combinations of described Flumetsulam and single phonetic sulphur ester, formulation is the one in missible oil, wetting powder, suspending agent, granule, microemulsion, aqueous emulsion, water-dispersible granules.
Described Herbicidal combinations, the application of the broad leaved weed in wheat paddock.
Flumetsulam belongs to triazolopyrimidine sulfonamides, is typical inhibitor of acetolactate synthetase.Protein biosynthesis block is made by suppressing the synthesis of branched-chain amino acid, plant stops growing, when its single dose uses, can exist the insensitive phenomenon of some weeds, and single phonetic sulphur ester is a kind of sulfonylurea weed killer herbicide, its mechanism of action is similarly inhibitor of acetolactate synthetase, by compounded combination between the two, the problem to some Weed-control effect difference when single dose uses can well be improved, thus play the effect of synergy.
The Pesticidal combination of the Flumetsulam that the present invention relates to and single phonetic sulphur ester, the auxiliary element in binary complex comprises acceptable organic solvent, emulsifier, surfactant, inert filler etc.; Wherein acceptable organic solvent comprises, fat hydrocarbon organic solvent, arene organic solvent, plant oil solvent, alcohol organic solvent, lipid organic solvent or organic solvent of ketone etc.; Adoptable surfactant has anionic surfactant and nonionic surface active agent.Other auxiliary element also comprises xanthans, the thickeners such as sodium carboxymethyl starch, the antifreezing agents such as ethylene glycol, glycerine, urea; The fillers such as kaolin, bentonite, attapulgite, charcoal acid calcium, and the acceptable stabilizing agent of other pesticidal preparations, safener, colouring agent etc.
The Herbicidal combinations of the Flumetsulam that the present invention relates to and single phonetic sulphur ester, have that herbicidal spectrum is wide, efficient, low toxicity, low-residual, synergistic effect significantly and reduce the features such as use cost, said composition preventive effect is significantly higher than the preventive effect of alone Flumetsulam and single phonetic sulphur ester, and can reduce the application dosage of each bioactivator.
The Herbicidal combinations of the Flumetsulam that the present invention relates to and single phonetic sulphur ester, after Flumetsulam and single phonetic sulphur ester are composite by a certain percentage, there is obvious synergistic effect, can be applicable to grassy weed such as Ma Tang, nutgrass flatsedge, green foxtail, the Ba Gencao etc. prevented and treated in wheat paddock and have good preventive effect, simultaneously to the broad leaved weed in wheat paddock as kitchen garden, acalypha copperleaf, black nightshade, lamb's-quarters, ivy glorybind etc. all have good preventive effect.
The present invention has following beneficial effect:
1, herbicidal composition provided by the invention, shows obvious synergistic effect, and the herbicidal effect of composition is significantly improved than single dose.Reduce pesticide cost and the adverse effect to ecotope, it applies huge Social benefit and economic benefit.2, this herbicidal composition adopts Flumetsulam to use with single phonetic sulphur ester mixture, there is wider herbicide spectrum and more excellent synergy control efficiency, can controlling broad leaved weed in wheat field effectively, to wheat growth safety when not only using, also can delay or overcome the drug-fast generation of weeds of wheat, be conducive to agricultural synthesis and administer.
