Description
Technical field
The present invention relates to a kind of agricultural chemicals suspension agent of pest control.
Background technology
The pyridine of piperazine worm, chemical name: 1-((6-chloropyridine-3-yl) methyl)-5-propoxyl group-7-methyl-8-nitro-1,2,3,5,6,7-, six hydrogen imidazo [1,2-a] pyridines.The pyridine of piperazine worm is the anabasine insecticide of new and effective, low toxicity, wide spectrum, is mainly used in preventing and treating homoptera pest, and rice fulgorid is had to good control efficiency.This medicament can be widely used in the control of the various crop insects such as fruit tree, wheat, soybean, vegetables, paddy rice and corn.
Avermectin, Chinese synonym: abamectin; Avermectin; White mite is clean; Desinsection element; A Ling; Pungent Ah's missible oil; English name: Abamectin, No. CAS: 71751-41-2.Avermectin be by large village of university, Japanese North intelligence etc. and the class that first Merck company of the U.S. develops there is desinsection, kill mite, ten hexa-atomic Macrocyclic lactone compounds of eelworm-killing activity, produced by Avid kyowamycin Streptomyces avermitilis fermentation in streptomycete.Avermectin has stomach toxicity and action of contace poison to mite class and insect, can not ovicidal.What mechanism of action was different from general insecticide is to disturb neurophysiology activity, stimulate and discharge γ-aminobutyric acid, and aminobutyric acid has inhibitory action to arthropodan nerve conduction.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent (Suspensionconcentrates, be called for short SC) claim again aqueous suspension agent, colloidal suspending agent, concentrated suspension, be under surfactant and other promoter effects, the former medicine that is insoluble to or is insoluble in water is distributed in water, form uniform and stable thick suspension system.Because its dispersion medium is water, so that suspending agent has cost is low, produce, storing and use the features such as safety, and easily mix with water, easy to use.Compared with the formulations of pesticide take organic solvent as medium, there is the advantages such as little to environmental influence of poisoning be light.
Summary of the invention
For solving the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of agricultural chemicals suspension agent of pest control.
Technical problem to be solved by this invention is achieved by the following technical solution:
The agricultural chemicals suspension agent of pest control, comprises the raw material of following weight percentage: piperazine worm pyridine 15-25%; Avermectin 15-25%.
The agricultural chemicals suspension agent of pest control, is made up of following materials by weight percentage: piperazine worm pyridine 15-25%; Avermectin 15-25%; Ethylene glycol 4-8%; Bentonite 0.05-0.15%; Surfactant 4-8%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, by 70-90 weight portion disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and poly-(Oxy-1,2-ethylidene) non-ionic surface active agent composition of 10-30 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate, English name: Sodium Lauryl Diphenyl Ether Disulfonate, No. CAS: 7575-62-4.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C2H4O) nC27H24O.English name: .alpha.-[tris
(Phenylmethyl)phenyl]-.omega.-hydroxy-poly(oxy-1,2-ethanediyl)Nonionic?surfactant。
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, formerly be mainly used in suppressing corrosion and the galvano-cautery in line cutting processing, sludge in softening working groove is used as rust-inhibiting additive in the silk thread of being careful cuts production process.In prior art, there is not any technology enlightenment of this raw material being played to dispersion moistening effect for agricultural chemicals reagent.
Agricultural chemicals suspension agent easily produces a large amount of bubbles in process, may affect metering and the packing of preparation.Therefore, can in formula, add the defoamer of 0.1-0.7wt%, can certainly adopt in process of production the method such as ultrasonic, vacuum defoamation to carry out froth breaking, and not need to add defoamer.Can also in formula, add according to actual needs mould inhibitor or pH adjusting agent.
The agricultural chemicals suspension agent of pest control of the present invention, be the pyridine of piperazine worm and abamectin compounded insecticidal suspending agent, can adopt the general method in this area to be prepared, one is ultramicro grinding method (also claiming wet grinding), and another kind is coacervation (also claiming hot melt-dispersion method).
Ultramicro grinding method:
(1) according to formula, the pyridine of piperazine worm, Avermectin, ethylene glycol, bentonite, surfactant and water are uniformly mixed to pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter≤4 μ m.
(3) be placed in homogenizer homogeneous, make particle homogenising.
Suspension refers to that former powder of dispersion keeps the ability of suspension time length in suspension, represents with suspensibility conventionally.A good suspending agent, should have good storage stability, i.e. higher suspensibility.
The agricultural chemicals suspension agent of pest control of the present invention has higher suspension rate, and long-term stable storage, can be used in control plant hopper and aphid.
