Description
Technical field
The present invention relates to a kind of plant insecticide suspending agent.
Background technology
Nylar, english common name: pyriproxyfen, other titles: going out, children is precious, pyriproxyfen chemical name: 4-phenoxy phenyl (RS)-2-(2-pyridine radicals oxygen) propyl ether.This product is the insect growth regulator, IGR that phenylate class upsets insect growth, belongs to the novel pesticide of juvenoid, has interior suction transfer activity, low toxicity, and the lasting period is long, to crop safety, and to fish low toxicity, the feature little to eco-environmental impact.Bemisia tabaci, scale insect, diamond-back moth, beet armyworm, prodenia litura, pear psyllid, thrips etc. are had to good control efficiency, and this product has good control efficiency to sanitary insect pests such as fly, mosquitoes simultaneously.There is mosquito, fly larvae pupation and the emergence effect of inhibition.Mosquito, fly larva contact this medicament, substantially, all in death in pupa time, can not sprout wings.This medicament lasting period reached about 1 month, and easy to use, and free from extraneous odour is good kill mosquito, fly medicine.
Diacloden, chemical name: 3-(the chloro-1,3-thiazoles-5-of 2-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine, English name Thiamethoxam, CAS 153719-23-4, EINECS 428-650-4.Diacloden is the anabasine insecticide of being developed by Novartis Co.,Ltd in 1991, its mechanism of action is similar to Imidacloprid, alternative inhibition insect central nervous system nicotinic acid nAChR ligands, and then the normal conduction of blocking-up insect central nervous system, death while causing insect to occur paralysis machine.Not only have tag, stomach toxicity, systemic activity, and there is higher activity, better safety, wider insecticidal spectrum and the feature such as speed of action is fast, the lasting period is long, be the better kind that replaces those are high to mammalian toxicity, have residual and environmental problem organic phosphor, carbamate, organochlorine insecticides.To coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, can effectively prevent and treat the insect of the insects such as various aphids, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner and knot polytype chemical pesticide generation resistance.With Imidacloprid, Acetamiprid, Nitenpyram without cross resistance.Both can be used for cauline leaf processing, seed treatment, also can be used for soil treatment.Suitable crop is rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus etc.Under recommended dose, use to crop safety, without poisoning.
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 plant insecticide suspending agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Plant insecticide suspending agent, comprises the raw material of following weight percentage: Nylar 15-25%; Diacloden 15-25%.
Plant insecticide suspending agent, is comprised of following materials by weight percentage: Nylar 15-25%; Diacloden 15-25%; Ethylene glycol 4-8%; Carboxymethyl cellulose 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

nc
27h
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.
Plant insecticide 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, Nylar, Diacloden, ethylene glycol, carboxymethyl cellulose, 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.
Plant insecticide suspending agent of the present invention has higher suspension rate, long-term stable storage.
