Abstract
The invention relates to a clodinafop-propargyl tribenuron-methyl weeding composition, a preparation method and an application thereof, and the clodinafop-propargyl tribenuron-methyl weeding composition belongs to an improved weeding composition. The weeding composition is a mixture consisting of a compound (A) and tribenuron-methyl and can effectively prevent and weed annual grassy weeds and broadleaf weeds. The weeding composition has obviously higher prevention effect than the single compound (A) or a single compound (B) and greatly reduces the application dose of various active substances.
Description
Technical field:
The present invention relates to have the Herbicidal combinations that improves performance.
Background technology:
The alkynes grass ester general by name of compound (A), chemistry 2-propynyl by name-(R)-2-4[4-(5-chloro-3-fluoro-2-pyridine oxygen base) phenoxy group] propionic ester is a kind of cornfield herbicidal.This weed killer herbicide can effectively be prevented and kill off mouse tail amur foxtail, wild oat, unreal oat, arm shape grass, lady's-grass, barnyard grass grass, yard grass, Annual Ryegrass, lamb's-quarters, rough stalked blue grass, setaria glauca, green foxtail, Shi Mao and the false Chinese sorghum etc. in the wheatland.Tribenuron-methyl can effectively be prevented and kill off annual broadleaf weeds such as clearvers in the wheatland, Veronica, descurainia sophia (l.) webb ex prantl, but alkynes grass ester and using with of tribenuron-methyl yet there are no report in wheatland.Therefore the immixture of alkynes grass ester and tribenuron-methyl is unforeseen.
Summary of the invention:
Herbicidal combinations provided by the invention, wherein be characterised in that and comprise component (A) 2-propynyl-(R)-2-4[4-(5-chloro-3-fluoro-2-pyridine oxygen base) phenoxy group] propionic ester, wherein as compound (A) and a kind of specific herbicides compounds (B) of active princlple formula
Alkynes grass ester (A)
Tribenuron-methyl (B):
The active constituent content of Herbicidal combinations of the present invention is: 1-90%wt
Weight ratio between compound in Herbicidal combinations of the present invention (A) and the compound (B) generally is:
(A) be 1-50 with tribenuron-methyl (B) ratio: 1
Herbicidal combinations provided by the present invention possesses the characteristics of broad weed-killing spectrum, can effectively prevent and kill off annual broadleaf weeds such as mouse tail amur foxtail, wild oat, unreal oat, arm shape grass, lady's-grass, barnyard grass grass, yard grass, Annual Ryegrass, lamb's-quarters, rough stalked blue grass, setaria glauca, green foxtail, Shi Mao and false Chinese sorghum in the wheatland and clearvers, Veronica, descurainia sophia (l.) webb ex prantl, preventive effect is significantly higher than the preventive effect of compound alone (A) or compound (B), and has reduced the application dosage of various active material significantly.
The present invention is used for cornfield herbicidal, can do the cauline leaf spraying and handle.
Adoptable surfactant has anionic surfactant and nonionic surface active agent.The aliphatic alcohol sulfate that comprises Sulfates, alkylol polyoxyethylene groups ether sodium sulfate etc., the sodium alkyl sulfonate of Sulfonates, alkylbenzenesulfonate, alkylnaphthalene sulfonate, dialkyl succinylsuccinate sulfonate, monoalkyl phenyl polyoxyethylene groups ether succinic acid sulfonate, fatty alcohol ethylene oxide adduct sulfonate, alkylphenol formaldehyde condensation product ethylene oxide adduct sulfonate, fatty alcohol epoxy vinyl ether, alkylphenol-polyethenoxy base ether, the anhydrous sorbitol fatty acid ester, anhydrous sorbitol aliphatic acid polyethenoxy base ether, alkylphenol formaldehyde condensation product polyoxyethylene groups ether, sulfonation castor-oil plant alkoxide, quaternary ammonium salt derivative, the condensation product of oxirane and nonyl or octyl phenol is a main product or by esterification and oxirane, the alkalies and alkaline earth salt of sulfuric ester and sulfonic acid is as sulphonyl amber ester octyl group sodium in two ninth of the ten Heavenly Stems and such as the alkali of the macromolecule sulfonic acid derivative of sodium lignin sulfonate and calcium and carboxylate of the anhydrous sorbierite that the alkali salt condensation forms etc.That can give an example has farming breast No. 2000 series, petroleum sodium sulfonate, dodecyl sodium sulfates, draws back powder, ethoxylated dodecyl alcohol sodium sulfonate, tween series etc.
Mixture, inert carrier and the filler and one or more lubricants and the dispersant that contain various active components in the Herbicidal combinations wetting powder of the present invention.Carrier is generally mineral inert substance such as potter's clay, kaolin, bentonite, talcum powder, diatomite etc.The wetting powder of the Herbicidal combinations of this invention contains the active component mixture of 1-90% (weight) (the more excellent 5-50% of being) usually, the dispersant of 0.25-25% (more excellent is 1-25%) (weight), 5-95% (weight) (more excellent is 5-80%) and inert solid carrier and filler.Form Herbicidal combinations jointly by them.
The missible oil of Herbicidal combinations of the present invention is constantly to stir in active component and solvent, the emulsifier reactor, to make the liquid that is dispersed into homogeneous phase transparent, so that spraying is used.Can suitably add safener, defoamer etc. as required.Suitable missible oil comprises the active component of 1-99% (weight) (the more excellent 3-50% of being).
The pulvis of Herbicidal combinations of the present invention is through abrasive dust processing and get with active ingredient and fine grain dispergated solid matter such as talcum powder, natural clay and kaolin, bentonite, pyrophyllite or the diatomite of being.Pulvis contains effective composition and is approximately 0.1-50% (weight), and more excellent is 2-30%.
The preparation of granule of the present invention is that active ingredient is sprayed at particulate inert material surface with absorption property or active ingredient is adhered to carrier mass surface or particulate inert material surfaces such as sand, kaolin with adhesives such as polyvinyl alcohol, Sodium Polyacrylate or mineral oil, also can the active ingredient that some is suitable be processed into granule with the method for common manufacturing granular fertilizer.Its active constituent content of dispersible granules agent (weight) between 5-90% in the water spreads fertilizer over the fields active constituent content (weight) between 1-50% in the granule, between the preferred 1-25%.
Embodiment:
Following examples describe the present invention in detail.Embodiment mainly is for the present invention is described, but not is used for limiting the present invention.
Embodiment 1 is the formulation preparation example, and embodiment 2 is a biological Examples,
Embodiment 1:
A: missible oil
Active component A with 20% and 20% active component B with as the alkylphenol-polyethenoxy base ether and 60% the toluene of emulsifier 10% as solvent, in reactor, mix and get final product.
The b wetting powder:
With the graininess white carbon of the neopelex as wetting agent of 20 parts of heavy compositions usefuls and 2 parts heavy, 10 parts of weights as adsorbent, 5 parts heavy in airslide disintegrating mill, form through ultramicro grinding as the sodium lignin sulfonate of dispersant and the kaolin of 63 parts of weights.
The c pulvis:
With mixing of 10 parts of heavy compositions usefuls and 90 parts of weights, in high speed disintegrator, pulverize and evenly form as the talcum powder of inert substance.
The d granule:
By the active ingredient composition of 20 parts of weights, the sodium lignin sulfonate of 20 parts of weights, 15 parts heavy dodecyl sodium sulfates, the kaolin of 25 parts of heavy polyvinyl alcohol and 25 parts of weights is made.
Embodiment 2, alkynes grass ester and tribenuron-methyl are used the preventive effect to wheat weeds with
Place: Jiangsu, Xinyi
Dispenser period: the weeds 2-3 leaf phase is investigated: the 30 day time behind the medicine: 2008
Conclusion: the actual preventive effect that alkynes grass ester and tribenuron-methyl are used with is higher than it and uses the expectancy theory preventive effect with, can enlarge simultaneously and kill the grass spectrum, proves the careless ester of alkynes and tribenuron-methyl has been used synergy with and careless spectrum effect is killed in expansion.
