Description
Technical field
The present invention relates to a kind of spinosad compound insecticidal suspending agent.
Background technology
Multiple killing teichomycin, having another name called pleocidin (Spinosad) is a kind of macrolides Nuisanceless high-efficient biological insecticides extracted in sugared many born of the same parents bacterium (Saccharopolysporaspinosa) zymotic fluid of thorn.Produce parent strain soil actinomycetes thorniness saccharopolyspora strain (the SaccharopolysporaspinosaMetrz & Yao) initial separation of pleocidin from one of Caribbean discarded wine brewing field.The researcher of The Dow Agrosciences, LLC.'s (being now Dow Agrosciences LLC) finds that this bacterium can produce the very high compound of insecticidal activity, and practical product is the mixture of spinosynA and spinosynB, therefore is called spinosad.Its mechanism of action is considered to the acting body of nicotinic acetylcholine receptors, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Pleocidin also can affect GABA acceptor, but mechanism of action is unclear.Insect can be made to benumb rapidly, paralyse, finally cause death.Its desinsection speed can compare favourably with chemical pesticide.Safety is high, and is the biological insecticides of low toxicity, efficient, low-residual without cross resistance with current common insecticide, and existing efficient insecticidal properties, has again the characteristic to having beneficial insect and mammalian safe, the most applicable pollution-free vegetable, Production of fruit application.It is the insecticide of a kind of low toxicity, efficient, wide spectrum.
Pymetrozine, chemical name: 4,5-dihydro-6-methyl-4-(3-pyridine methylene is amino)-1,2,4-3 (2H)-one, No. CAS: 123312-89-0, English name: Pymetrozine.Pymetrozine has action of contace poison to insect, also has systemic activity simultaneously.Can also can at phloem transport in xylem transporting in plant corpus; Therefore both can be used as foliar spray, also can be used for soil treatment.Due to the transporting characteristic that it is good, the branches and leaves newly grown after cauline leaf spraying also can be effectively protected.
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 spinosad compound insecticidal suspending agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Spinosad compound insecticidal suspending agent, comprises the raw material of following weight percentage: multiple killing teichomycin 15-25%; Pymetrozine 5-15%.
Spinosad compound insecticidal suspending agent, is made up of following materials by weight percentage: multiple killing teichomycin 15-25%; Pymetrozine 5-15%; Propane diols 4-8%; Carboxy-propyl 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: SodiumLaurylDiphenylEtherDisulfonate, 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

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.
Spinosad compound insecticidal 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, multiple killing teichomycin, pymetrozine, propane diols, carboxy-propyl 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.
Spinosad compound insecticidal suspending agent of the present invention has higher suspension rate, stable during long-term storage, for preventing and treating thrips, Homoptera, diptera, lepidoptera pest etc.
