Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of agriculture chemical compounding insecticide, be specifically related to Rynaxypyr and the composite suspending agent of ethyl pleocidin and preparation method thereof.
Background technology
Contain a large amount of organic solvents in the chemical pesticide, when making huge contribution, also brought serious pollution to natural environment for agricultural foison.Along with environmental regulation becomes better and approaching perfection day by day, the cry that reduces pesticide pollution is strong day by day.Develop safely, environmental protection and cheap novel liquid formulation are to reduce or eliminate the trend of the times of organic solvent harm having become agricultural chemicals development.Wherein, Water-borne modification is exactly one of dominant direction of formulations of pesticide development.This type pesticides new formulation also can increase new characteristic to agricultural chemicals; More can give full play to the function Characteristics of former medicine self, overcome and remedy the deficiency of the original formulation of agricultural chemicals, all lower to people and animals' toxicity and excitant; And can alleviate poisoning to crop; Improve physico chemistry and biological property, expanding application scope, the service life of prolongation medicament.
Agricultural chemicals suspension agent belongs to one of Water-borne modification novel form, is pesticide active ingredient and dispersant, wetting agent, thickener, antifoaming agent, antifreezing agent etc. are dispersed in the matrix water and the high dispersive that forms, stable suspended substance.Agricultural chemicals suspension agent has the advantage of wetting powder and missible oil concurrently: aspect drug effect, the suspending agent herbicide effects is superior to wetting powder, and the insecticide effect is then close with missible oil; Because agricultural chemicals suspension agent is dispersion medium with water, make it have environmental protection, cheap characteristics, reduced the use of a large amount of organic solvents simultaneously, production process safety, pollution-free; And suspending agent can mix with arbitrary proportion with water, and is easy to use, can reach bigger coverage rate after the dilution, can be processed to the formulation of high concentration.
The Rynaxypyr chemical name is 3-bromo-N-{4-chloro-2-methyl-6-[(methylamino) carbonyl] phenyl }-1-(3-chloro-2-pyridine radicals)-1H-pyrazoles-5-acid amides.Rynaxypyr is a kind of brand-new high-efficient low toxicity insecticide, and insecticidal mechanism is different with traditional insecticide.Rynaxypyr can efficiently activate ryania (muscle) acceptor of insect, makes it excessively discharge the calcium ion in the intracellular calcium store, causes the insect paralysis dead.Rynaxypyr has tags and stomach poison function; Show efficient, wide spectrum, hold and imitate and characteristics such as mechanism of action novelty, can be used for preventing and treating multiple lepidoptera pest, other commercialization insecticide varieties that its control efficiency obviously is superior to using in the current production; There is not cross resistance in other insecticides; And, can be used for the comprehensive regulation and the resistance management of insect, the various pests that is used to prevent and treat crops such as vegetables, beet, cotton to natural enemy insect safety; Like beet armyworm, tomato moth, diamond-back moth, imported cabbageworm, cotton bollworm, pink bollworm etc., each instar larvae all there is good control efficiency.
Ethyl pleocidin is made up of ethyl pleocidin-J and two kinds of components of ethyl pleocidin-L, and ethyl pleocidin-J outward appearance is a white powder, and ethyl pleocidin-L outward appearance is white to yellow crystals, band semen armeniacae amarae flavor.Ethyl pleocidin acts on nAChR and r-reanal acceptor in the insect nerve, causes polypide insensitive to the signal transfer reaction of excitability or inhibition, influences normal nervous activity, until death.Ethyl pleocidin has stomach toxicity and action of contace poison, is mainly used in control diamond-back moth, beet armyworm, Liriomyza, prodenia litura and lima bean pod borer.
At present, do not see have that Rynaxypyr and ethyl pleocidin are composite to be the report of suspending agent.
Summary of the invention
The objective of the invention is deficiency, a kind of Rynaxypyr and the composite suspending agent of ethyl pleocidin and preparation method thereof are provided to prior art.Composite suspending agent preparation technology of the present invention is simple, production cost is lower.
Rynaxypyr insecticidal action mechanism is different from ethyl pleocidin, and the two is composite for not only having enlarged the control of insect spectrum behind the suspending agent, and has increased the action target spot of medicament, can delay pest resistance to insecticide.
The water-insoluble solid pesticide processing is become suspending agent, itself is a kind of thermodynamic unstable system between colloid and rough segmentation system.The present invention is added with auxiliary agents such as wetting agent, dispersant and antifreezing agent in the preparation process of suspending agent, the main effect of wetting agent and dispersant is: increase the dispersion medium viscosity, reduce the difference in specific gravity between dispersion medium and the disperse phase.Coordinate each other through auxiliary agent and active component, kept stability of formulation.The prepared suspending agent of the present invention has that particle diameter is little, biologically active is high and characteristics such as using dosage is low, and is medium with water, and it is environmentally friendly.
For reaching above purpose, the present invention has adopted following technical scheme:
The composite suspending agent of Rynaxypyr and ethyl pleocidin, by weight percentage, the consisting of of its proportioning raw materials each component: Rynaxypyr 0.5～25%; Ethyl pleocidin 0.1～15%, dispersant 1～5%, wetting agent 0.5～4%; Thickener 0.1～4%, antifreezing agent 1～8%, preservative 0.1～0.8%; Antifoaming agent 0.1～0.5%, water 49.4～87.8%;
Said dispersant is one or both in calcium lignosulfonate, sodium metnylene bis-naphthalene sulfonate and the AEO;
Said wetting agent is one or both in isopropyl naphthalene sodium sulfonate, sodium alkyl sulfonate and the phenethyl phenol polyethenoxy ether sodium sulfate;
Said thickener is xanthans or polyvinyl alcohol;
Said antifreezing agent is ethylene glycol or urea;
Said preservative is sodium salicylate or Sodium Benzoate;
Said antifoaming agent is a n-octyl alcohol.
Further, said water is preferably distilled water or deionized water.
Said Rynaxypyr preferably accounts for 5～20% in the weight proportion of material component, ethyl pleocidin preferably accounts for 5～10% in the weight proportion of material component.
The preparation method of described Rynaxypyr and the composite suspending agent of ethyl pleocidin; Press the material component proportioning; After evenly, obtaining particle diameter through sand milling, screening again is Rynaxypyr and the composite suspending agent of ethyl pleocidin of 0.5～5 μ m with Rynaxypyr, ethyl pleocidin, dispersant, wetting agent, thickener, antifreezing agent, preservative, antifoaming agent and water mixed and dispersed.
Further, the rotating speed of dispersion is 1000～2900r/min, and the time is 30～60min.
The rotating speed of said sand milling is 1400～1600r/min, and the time is 1～3h.
The present invention compared with prior art has following advantage:
(1) the composite suspending agent of the present invention is wide to the control of insect spectrum, and insect is difficult to develop immunity to drugs;
(2) preparation technology of the composite suspending agent of the present invention is simpler, and production cost is lower;
(3) do not use a large amount of organic solvents in the production process of the composite suspending agent of the present invention, safety and environmental protection, environmental pollution is little;
