Abstract
The invention relates to a compound pesticide suspending agent. The compound pesticide suspending agent comprises the following materials in percentage by weight: 10-20% of thiacloprid, 10-20% of pyridaben, 4-8% of ethanediol, 0.05-0.15% of xanthan gum, 4-8% of a surface active agent and the balance of water. The compound pesticide suspending agent has the advantages that the suspensibility is high, the long-time storage is stable, and the agricultural insects can be controlled, such as tea lesser leafhopper and aleurocanthus spiniferus.
Description
Technical field
The present invention relates to a kind of agriculture chemical compounding suspending agent.
Background technology
Thiacloprid, chemical name: (3-((6-chloro-3-pyridyl base) methyl)-1,3-thiazoles quinoline-2-subunit) cyanamide, No. CAS]: 111988-49-9.The former medicine of thiacloprid (Thiacloprid) is developed cooperatively by Bayer Bitterfeld GmbH Nong Hua company and Japanese Bayer Nong Hua company, is novel chloro nicotinic insecticide.The mechanism of action of thiacloprid and other conventional pesticides are different.Its Main Function engages caudacoria in insect nerve, by being combined with nAChR, and interference insect nervous system normal conduction, cause the obstruction of neural channel, cause a large amount of accumulation of acetylcholine, thereby make insect exaltation, whole body spasm, paralysis and dead.There is stronger interior suction, tag and stomach poison function, there is no cross resistance with common insecticides as pyrethroid, organic phosphates and carbamates, thereby can be used for resistance management.
Pyridaben, chemical name: the 2-tert-butyl group-5-(4-tert-butyl group benzylthio)-4-chlorine pyridazine-3-(2H) ketone, No. CAS: 96489-71-3.Efficiently, wide spectrum miticide, without interior absorption, tetranychid, Panonychus citri, unguiculus mite are closed to the planting property of food such as goitre mite evil mite and all there is obvious control efficiency, and if to ovum mite, become mite all effective, to becoming the mobile phase of mite also effective.Be applicable to citrus, apple, pears, hawthorn, cotton, tobacco, vegetables (except eggplant) and ornamental plants.As when preventing and treating the blister mites such as citrus and European red mite, pears and hawthorn, in evil, all can use (for improving when control efficiency is preferably in 2～3, average every leaf, using) the mite emergence period, 20% wetting powder or 15% missible oil are diluted to 50～70mg/L (2300～3000 times) spraying to water.Safety interval is 15 days, in results, within first 15 days, discontinues medication.
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 agriculture chemical compounding suspending agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Agriculture chemical compounding suspending agent, comprises the raw material of following weight percentage: thiacloprid 10-20%; Pyridaben 10-20%.
Agriculture chemical compounding suspending agent, is comprised of following materials by weight percentage: thiacloprid 10-20%; Pyridaben 10-20%; Ethylene glycol 4-8%; Xanthans 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: (C

24o.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 methods 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.
Agriculture chemical compounding suspending agent of the present invention can adopt the general method in this area to be prepared, and 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, thiacloprid, pyridaben, ethylene glycol, xanthans, 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.
Agriculture chemical compounding suspending agent of the present invention has higher suspension rate, and long-term stable storage, can prevent and treat pest, as tea lesser leafhopper and Aleurocanthus spiniferus.
