The invention has stable physical and chemical property and difficult decomposition and degeneration, needs no organic solvent, has no dust entrainment, can not burn and explode, saves the petroleum resources, reduces the environmental pollution, is safe for operators and environments in the production and usage process, can be processed into a high-content preparation as required and saves the packing, storage and transportation cost.
Description
Technical field
The invention belongs to formulations of pesticide fields, be specifically related to a kind of pymetrozine water dispersing granule and preparation method.
Background technology
Pymetrozine belongs to pyridines or Triazinone insecticide, is the brand-new non-insects agent of killing livestock, and is developed in 1988 by Switzerland Ciba-Geigy company the earliest, and this product shows excellent control efficiency to the sucking pest of various crop.Utilizing electricity to penetrate figure (EPG) technology studies show that, no matter be drop, feed or test injection, almost produce immediately the lancet blocking effect as long as aphid or plant hopper one touch pymetrozine, stop at once taking food, and final hungry lethal, and this process is irreversible.Therefore, pymetrozine has the excellent malicious function of blocking-up insect biography.Although at present the caused lancet obstruction of pymetrozine mechanism be it be unclear that, existingly studies show that this irreversible " stopping eating " is not because " Antifeedant Effects " causes.The initial lethality of insect after pymetrozine is processed is very low, still can survive a few days before insect " hungry moth " is lethal, and the lethality height is relevant with weather conditions.Test shows, in chemicals treatment 3 hours, the feeding activity of aphid reduces by 90% left and right, processes rear 48 hours, and lethality can be near 100%.Pymetrozine has action of contace poison to insect, also has simultaneously systemic activity.Can also can be at phloem transport in the xylem transporting in plant corpus; Therefore both can be used as foliar spray, also can be used for soil treatment.Due to its good transporting characteristic, the branches and leaves that newly grow after the cauline leaf spraying also can be effectively protected.Common formulations is 25% wetting powder at present, and in order to adapt to the greenization of chemical pesticide preparation, water dispersible granules is well to substitute formulation.
Summary of the invention
The objective of the invention is to overcome the defective that the pymetrozine wetting powder need consume mass filler and environment be caused severe contamination, develop a kind of environment-friendly highly efficient, broad spectrum pesticide that contains pymetrozine.
Purpose of the present invention can reach by following measures:
A kind of pymetrozine water dispersing granule, its quality group becomes: pymetrozine 5～80%, dispersant 2～25%, disintegrant 2～20%, wetting agent 1～15%, binding agent 0～10%, filler complements to 100%; Its preferred quality group becomes: pymetrozine 10～75%, and dispersant 5～25%, disintegrant 5～15%, wetting agent 1～15%, binding agent 1～5%, filler complements to 100%.
the dispersant that the present invention selects comprises lignosulfonates, alkyl sulfate, alkylsulfonate, naphthalene sulfonic acid-formaldehyde condensation product, the styryl phenol polyethenoxy ether, alkylaryl polyoxyethylene polyoxy third rare ether, alkylaryl methyl ether resin APEO, Alpha-Methyl Bian Ji APEO, the alkyl sulfonic acid salt anionic surfactant, the phosphate type anion surfactant, polycarboxylate etc., preferred dispersant is alkylaryl sulfonates, sodium methylene bis-naphthalene sulfonate, fatty alcohol-polyoxyethylene ether, aliphatic alcohol sodium sulfate, the cocoyl sodium sulfonate, one or more of polycarboxylate or 16 carbon fatty alcohol sodium sulphate, polycarboxylate most preferably.
Be applicable to disintegrant of the present invention and comprise starch, mineral salt, sodium carboxymethyl starch, polyvidone etc., preferred disintegrant is sodium carboxymethyl starch or polyvidone, most preferably sodium carboxymethyl starch.
Be applicable to wetting agent of the present invention alkyl sulfate, naphthalene sulfonic acid-formaldehyde condensation product are arranged, styryl phenol polyethenoxy ether, alkylaryl polyoxyethylene polyoxy third rare ether, alkylaryl methyl ether resin APEO, Alpha-Methyl Bian Ji APEO, alkyl sulfonic acid salt anionic surfactant, phosphate type anion surfactant etc., preferred wetting agent is lauryl sodium sulfate, to methoxyl group fatty acyl amido benzene sulfonic acid sodium salt or sodium butylnaphthalenesulfonate, most preferably be methoxyl group fatty acyl amido benzene sulfonic acid sodium salt.
Binding agent of the present invention such as xanthans, gum Arabic, cellulose base compound, starch compound etc.Preferred binding agent is sodium carboxymethylcellulose, Ac-Di-Sol, polyvinyl alcohol or gum Arabic; Most preferably sodium carboxymethylcellulose or Ac-Di-Sol.
Filler of the present invention such as bentonite, white carbon, mineral salt etc., preferred filler is the mineral salt such as sodium sulphate, urea, ammonium sulfate or sodium chloride, most preferably is anhydrous sodium sulfate.
Water dispersible granules of the present invention adopts the processing technology of mixing-pulverizing-mixing-granulation again-screening.Concrete preparation method is: pymetrozine, dispersant, disintegrant, wetting agent and filler are carried out coarse crushing, then mix, carry out again ultra-fine grinding, after obtaining particle diameter and crossing the superfine powder of 1000 orders with top sieve, add again binding agent to carry out granulation, sieve with vibratory sieve at last, obtain finished product.
Be compared with the prior art, advantage of the present invention and good effect are:
1, neither need to use organic solvent, there is no again the dust drift, can not burn, can not explode, can save petroleum resources and alleviate environmental pollution, produce and use procedure in to operator and Environmental security.
2, the preparation of high-load be can be processed into as required, packing, storage, cost of transportation saved.
3, physics, stable chemical performance are difficult for decomposing rotten.
4, finished product is granular solids, good fluidity, and not sticking wall after toppling over can not remain in and form secondary pollution in packing container.
5, available papery packing is convenient to reclaim and is destroyed or natural degradation.
6, the powder diameter is superfine, is conducive to target and fully absorbs and play a role, and can reduce the effective ingredient consumption, improves effect.
7, meaning of the present invention is not only to research and develop out environment-friendly highly efficient, broad spectrum pesticide; but can be extended on other super-high-efficient insecticide, bactericide, weed killer herbicide and plant growth regulator by the present invention; improve the level of processing of China's formulations of pesticide; to improve the availability of pesticide active ingredient; reduce the use of auxiliary agent, organic solvent, auxiliary material; reduce to greatest extent the negative effect that agricultural chemicals brings environmental protection; promote simultaneously China's agricultural chemicals competitiveness in the international market, for country strives for foreign exchange.
8, the water dispersible granules of formula of the present invention (particularly special formulation) is compared with wetting powder, has stronger control efficiency, its short-term and mid-term control efficiency apparently higher than the latter.Its physics, stable chemical performance are difficult for decomposing rotten
