Abstract
The invention discloses a kind of synergistic composition and preparation method thereof, belongs to medicine compounding field.The synergistic composition, its active ingredient is mesotrione (A), cyanazine (B), ametryn (C), and the mesotrione, cyanazine, the weight ratio of ametryn are 20 1:1‑10:1‑20.Active ingredient compounding in the present invention has obvious synergistic effect, can effectively reduce the amount of application of each single dose；Said composition can add the auxiliary element for allowing to use in remaining pesticide and be processed into any formulation.
Description
Technical field
The present invention relates to medicine to compound field, particularly relates to a kind of synergistic composition and its application.
Background technology
Herbicide (herbicide) refers to make weeds that withered medicament thoroughly or selectively occur, also known as herbicide,
To eliminate or suppress a kind of material of plant growth.Herbicide is the pesticide species of current dosage maximum, due to long-term a large amount of
Use, the resistance problems of farmland weed are increasingly severe.
Mesotrione (mesotrione) also known as mesotrione, are that one kind can suppress medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dioxygen
With after seedling wide spectrum selective herbicide before the bud of change enzyme (HPPD), it can effectively prevent main broadleaved herb and some grass family are miscellaneous
Grass.Mesotrione molecular formula C14H13NO7S, molecular weight 339.32, CAS 104206-82-8.Mesotrione sterling appearance is pale yellow
Color solid；Fusing point：165.3 DEG C (with decomposing)；Vapour pressure (20 DEG C)：<5.7×10-6pa；Solubility (20 DEG C) in water：
0.16mg/mL；Its appearance of active compound mass fraction >=94%. is Sandy to the opaque solid of sand；Fusing point：148.7~152.5
DEG C, start simultaneously at decomposition；Solubility (g/L)：Dimethylbenzene 1.4, toluene 2.7, methanol 3.6, acetone 76.4, dichloromethane 82.7,
Acetonitrile 96.1；Heat storage stability：The active compound is stored 14d properties at 54 DEG C and is stablized.
Cyanazine, other titles：Hundred this, bladex, Bladex, Foxtrol.Cyanazine is interior suction selective herbicidal
Agent, is mainly absorbed by root, and leaf can also absorb.To corn safety, lasting period 2-3 month, on rear stubble wheat without influence.Weeding is lived
Property with soil organic matter content and quality have substantial connection.Organic matter is more or then herbicide dosage also needs suitably to increase for clay.
In Sha Xingchong, easily there is poisoning when few in the content of organic matter.Herbicide wide spectrum, can prevent and kill off most of 1 year raw grassy weed and broad-leaved
Weeds.
Ametryn, chemical name：The chloro- 4- diethylin -6- isopropylamine bases -1,3,5-triazines of 2-；Other titles：Aunar is drawn
Tianjin, Aatrex, Primatola, gram esaprim, grams -30027.Physicochemical property：Appearance is white powder, fusing point 173-175
DEG C, vapour pressure at 20 DEG C is 40 μ Pa, and solubility in water is 33mg/L, chloroform 28g/L, acetone 31g/L, ethyl acetate
24g/L, methanol 15g/L, relatively stablize in slightly sour or alkalescence medium, but at relatively high temperatures, alkali or inorganic acid can make its water
Solution.Ametryn is the selective before seedling of interior suction, after seedling closing herbicide.Based on root absorbs, cauline leaf absorbs seldom.Herbicide acts on and choosing
The same Simanex of selecting property, is easily eluted to soil deeper by rainwater, also effective to some deep root grass, but is also easy to produce poisoning, imitates the phase
It is longer.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of synergistic composition and its application, to meet the need of agricultural production
Will, active component included in composition has mutually synergistic effect to improve preventive effect and is beneficial to delay drug-fast generation.
The synergistic composition of the present invention, its active ingredient is mesotrione, cyanazine, ametryn, mesotrione, cyanogen grass
Tianjin, the weight ratio of ametryn are 20-1:1-10:1-20, is preferably 1:1-10:1-20, remaining be pesticide in allow use and can
The auxiliary element of receiving.
Active ingredient accounts for the 0.1%-99% of pesticidal preparations in the synergistic composition of the present invention, and what is used in pesticidal preparations helps
Agent, which includes wetting agent, dispersant, emulsifying agent, solvent and filler etc. and other, is beneficial to active ingredient stable and medicine in the formulation
The known substance played is imitated, is all to commonly use in pesticidal preparations or allow the various composition used, has no specific restriction, possess component
Determined with dosage according to recipe requirements by simple experiment.
The synergistic composition of the present invention can be prepared into any one formulation of suitable agricultural use with known method, than
Preferable formulation is wettable powder, suspending agent, microemulsion, water dispersible granules, solvable pulvis.
Composition described in the invention can be provided in the form of finished product preparation, i.e., each material has mixed in compound,
The component of composition can also be provided with unit dose form, directly mixed, be then diluted to required in bucket or tank using preceding
Concentration.
The synergistic composition of the present invention is prevented and kill off more suitable for the crop fields such as corn, pea, broad bean, potato, sugarcane, cottons
Kind grassy weed and broad leaved weed；Broad leaved weed is field bindweed, clearvers, thorn dish, three-coloured amaranth, piemarker etc.；Grassy weed is
Wild oat, bromegrass, Triticum tauschii, amur foxtail, barnyard grass, herba setariae viridis grass, lady's-grass etc..The synergistic composition of the present invention can be by common
Method is applied, and such as cast, injection, spraying, dusting or spread, its amount of application change with weather condition or crop condition.
Compared with prior art, the beneficial effects of the present invention are：1st, compared with single dose, there is compounding obvious collaboration to increase
Effect acts on, and improves prevention effect；2nd, composition is made of two kinds of different active ingredients of mechanism of action, is conducive to overcome and is prolonged
Delay drug-fast generation；3rd, composite reagent reduces dosage, so as to reduce cost and alleviate the pollution to environment；4th, with
Herbicide is used alone to compare, producing the risk of poisoning reduces.
Embodiment
To make the technical problem to be solved in the present invention, technical solution and advantage clearer, specific embodiment will be used below
It is described in detail, but the present invention is limited to absolutely not these examples.As described below is only the preferable embodiment of the present invention, only to
