Description
Technical field
The present invention relates to a kind of flumorph and iprovalicarb compound insecticidal suspending agent.
Background technology
Flumorph, English name flumorph; SYP-190, chemical name: (E, Z) 4-[3-(37,4'-=methoxyphenyl)-3-(4-fluorophenyl) acryloyl] morpholine.Belong to morpholine class disinfectant use in agriculture.Effective especially to Peronospora, epidemic disease mycin germ.To the Oomycete on grape, potato and tomato, especially Peronosporaceae and Phytophthora bacterium have fungicidal effectiveness.
Iprovalicarb, English name: iprovalicarb, chemical name: 2-methyl isophthalic acid-[(1-p-methylphenyl ethyl) carbamoyl]-(S)-propyl carbamic acid isopropyl ester.Amino acid amide series bactericidal agent, be applicable to various crop and prevent and treat downy mildew, epidemic disease class, it can be used for cauline leaf and soil treatment.
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 flumorph and iprovalicarb compound insecticidal suspending agent.
Technical problem to be solved by this invention is achieved by the following technical solution:
Flumorph and iprovalicarb compound insecticidal suspending agent, comprise the raw material of following weight percentage: flumorph 5-15%; Iprovalicarb 25-35%.
Flumorph and iprovalicarb compound insecticidal suspending agent, be made up of following materials by weight percentage: flumorph 5-15%; Iprovalicarb 25-35%; Glycerine 4-8%; Polyvinylpyrrolidone 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

(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.
Flumorph of the present invention and iprovalicarb compound insecticidal suspending agent 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, flumorph, iprovalicarb, glycerine, polyvinylpyrrolidone, 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.
Flumorph of the present invention and iprovalicarb compound insecticidal suspending agent have higher suspension rate, stable during long-term storage, for preventing and treating plurality of plant diseases especially downy mildew, the epidemic disease in cereal, vegetables, fruit tree, flowers and other crops.
