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, and belong to the novel pesticide of juvenoid, have interior suction transfer activity, low toxicity, the lasting period is long, to crop safety, to fish low toxicity, and the feature little to eco-environmental impact.Have good control efficiency to Bemisia tabaci, scale insect, diamond-back moth, beet armyworm, prodenia litura, pear psyllid, thrips etc., this product has good control efficiency to the sanitary insect pest such as fly, mosquito simultaneously.Have and suppress mosquito, fly larvae pupation and emergence effect.Mosquito, fly larva contact this medicament, substantially all dead in pupa time, can not sprout wings.This medicament lasting period reaches about 1 month, and easy to use, free from extraneous odour, is good kill mosquito, fly medicine.
Diacloden, chemical name: 3-(the chloro-1,3-thiazoles of 2--5-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 developed by Novartis Co., Ltd in 1991, its mechanism of action is similar to Imidacloprid, alternative suppress insect CNS nicotinic acetylcholine esterase acceptor, and then block the normal conduction of insect CNS, dead when 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 replace that those are high to mammalian toxicity, there have to be residual and the organic phosphor of environmental problem, carbamate, organochlorine insecticides better kind.To coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, effectively can prevent and treat the insect of the insects such as various aphid, 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 process, seed treatment, also can be used for soil treatment.Suitable for crop is rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus etc.Use to crop safety, without poisoning under recommended dose.
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) also known as aqueous suspension agent, colloidal suspending agent, concentrated suspension, be under surfactant and other promoter effects, the former medicine being insoluble to or being insoluble in water be distributed in water, form uniform and stable thick suspension system.Because its dispersion medium is water, thus suspending agent to have cost low, to produce, the feature such as storing and use safety, and easily mix with water, easy to use.Compared with taking organic solvent as the formulations of pesticide of 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 made up 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, is made up of 70-90 weight portion disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of 10-30 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate, English name: Sodium Lauryl Diphenyl EtherDisulfonate, 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
2h
4o)
nc
27h
24o.English name: .alpha.-[tris (Phenylmethyl) phenyl]-.omega.-hydroxy-poly (oxy-1,2-ethanediyl) Nonionicsurfactant.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, former being mainly used in suppresses the corrosion in linear cutter and galvano-cautery, sludge in softening working groove, is used as rust-inhibiting additive in low-speed WEDM production process.In prior art, do not have and this raw material is used for any technology enlightenment that agricultural chemicals reagent plays dispersion moistening effect.
Agricultural chemicals suspension agent easily produces a large amount of bubble in process, may affect metering and the packaging of preparation.Therefore, the defoamer of 0.1-0.7wt% can be added in formula, the method such as ultrasonic, vacuum defoamation can certainly be adopted in process of production to carry out froth breaking, and not need to add defoamer.Mould inhibitor or pH adjusting agent can also be added according to actual needs in formula.
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 known as wet grinding), and another kind is coacervation (also known as hot melt-dispersion method).
Ultramicro grinding method:
(1) according to formula, Nylar, Diacloden, ethylene glycol, carboxymethyl cellulose, surfactant and water are uniformly mixed 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 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Suspension refers to that former powder of dispersion keeps the ability of suspension time length in suspension, usually represents with suspensibility.A good suspending agent, should have good storage stability, namely higher suspensibility.
Plant insecticide suspending agent of the present invention has higher suspension rate, stable during long-term storage.
