Description
Technical field
The present invention relates to a kind of pymetrozine film-spreading oil solution and corresponding film-spreading oil solution thereof and diffusant.
Background technology
Pymetrozine (Pymetrozine) chemical name: 4,5-dihydro-6-methyl-4-(3-pyridine methylene is amino)-1,2,4-3 (2H)-one, belong to pyridines or Triazinone insecticide, be brand-new non-killing livestock property insecticide, by Ciba-Geigy company of Switzerland in exploitation in 1988, the sucking pest of this product to various crop shows excellent control efficiency.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.
Pymetrozine mainly based on water dispersible granules, suspending agent, wetting powder at pesticide market application forms, improve pymetrozine control efficiency in use, increase operation rate, must improve usage amount, and this can cause larger pollution to environment.
Several formulation in use all wants dilute with water spray to spray above.Pymetrozine uses to be not limited to dilute with water spraying by the present invention, is directly sprinkled into or also can forms the homogeneous medicine film of spread in water surface diffusion rapidly after instilling the water surface, and can climb on plant by capillarity, playing a protective role.
At present, China, in paddy field damage by disease and insect Techniques For Chemical Control, generally adopts Conventional mass spray technique, time-consuming.Be badly in need of in production developing comparatively labour-saving pesticide application technology, film-spreading oil solution belongs to the water surface and sprawls preparation category.
The water surface of domestic and international development is sprawled preparation and be substantially divided into two classes in formulation selection: one is make carrier with solid matter, adds solvent or granule made by disintegrant, at applied atop hydrophober; Two is make the former medicine of carrier solubilizes with organic solvent.But consequent problem is: when making carrier with solid matter, along with the dissolving of water-solubility carrier, if active ingredient is also water-soluble, then can spread because of concentration difference, active ingredient is caused all to be dissolved in water body, to ensure the valid density that control efficiency then must make water body reach certain, so not only wasting and also can cause great harm to aquatile, people, animal etc.
If active ingredient is slightly water-soluble, be then difficult to ensure that the active ingredient be equipped on solid carrier can be uniformly distributed in water; And granule is easily because being rubbed when transporting and store and transport and extrude and be Powdered, affects drug effect and plays.If make dicyandiamide solution with common organic solvents, also can because of the toxicity of solvent contaminated environment; Meanwhile, with the volatilization of solvent, the active component in preparation can crystal aggregation becomes solid particulate to separate out because of its slightly water-soluble, is difficult to the valid density uniformity keeping it in water.
Summary of the invention
Object one of the present invention is the insecticide-applying way of the former medicine changing crop in existing water, a kind of film-spreading oil solution used for the former medicine of auxiliary interior absorption is provided, be characterized in that preparation can spread rapidly and form homogeneous medicine film on the water surface, and climb at nearly water plant position and form medicine film spread.
Object two of the present invention is to provide a kind of pymetrozine film-spreading oil solution.
Object three of the present invention is to provide a kind of efficient diffusant of film-spreading oil solution.This diffusant has lower surface tension, former for interior absorption the effective elements of the medicine can be spread rapidly at the water surface, and keep not breaking of medicine film for a long time.
Object of the present invention can be achieved through the following technical solutions: a kind of film-spreading oil solution for the former medicine of interior absorption, and it is formulated by weight primarily of following component: solvent carrier 1-93.5 part, diffusant 1-20 part and spreading aids 1-50 part; Described diffusant comprises environment-friendly type surfactant, this environment-friendly type surfactant primarily of C12 fatty alcohol polyoxypropylene polyoxyethylene ether phosphate and organosilicone polyoxyethylene ether in mass ratio routine 1:3 ~ 3:1 mix.
Described solvent carrier comprises: one or more the arbitrary proportion mixing of green solvent, soybean oil, corn oil, methyl laurate.
Described green solvent mixes according to mass ratio 1:5 ~ 5:1 primarily of sesquiterpene vegetable oil, methylated vegetable oil.
Described diffusant also comprises one or more the arbitrary proportion mixing of sulphosuccinates, sorbitol ester APEO, lauryl sulfate, phenethyl phenol polyethenoxy ether phosphate, triphenoethyl benzene phenol polyoxyethylene polyoxypropylene block polymer phosphate.
Described spreading aids mixes primarily of one or more arbitrary proportion of polyacrylamide, isopropyl alcohol, n-butanol, acetone, propane diols, 1-METHYLPYRROLIDONE, spectrasolv DMDA.
Further, a kind of film-spreading oil solution for the former medicine of interior absorption of the present invention, it is formulated by weight primarily of following component: solvent carrier 1-93.5 part, diffusant 1-20 part and spreading aids 5-50 part.
A kind of pymetrozine film-spreading oil solution, it comprises pymetrozine and solvent carrier film-spreading oil solution; Described pymetrozine and film-spreading oil solution ratio of weight and number are: 0.5 ~ 30:70 ~ 99.5.
A kind of diffusant, it comprises environment-friendly type surfactant, this environment-friendly type surfactant primarily of C12 fatty alcohol polyoxypropylene polyoxyethylene ether phosphate and organosilicone polyoxyethylene ether in mass ratio routine 1:3 ~ 3:1 mix.
The preparation method of pymetrozine film-spreading oil solution of the present invention, that described solvent carrier, spreading aids are uniformly mixed by agitator in common beaker, then add pymetrozine, and constantly stir until solution becomes completely transparent with agitator, then add diffusant and stir.
Technological merit of the present invention is: film-spreading oil solution of the present invention belongs to the one of biological organic solvent, especially green solvent (sesquiterpene vegetable oil, methylated vegetable oil) is employed environmentally friendly, do not dissolve each other with water, and proportion is less than water, in use can swim on the water surface for a long time, be conducive to forming medicine film; Environment-friendly type surfactant (C12 fatty alcohol polyoxypropylene polyoxyethylene ether phosphate and organosilicone polyoxyethylene ether) has lower surface tension, pymetrozine active ingredient can be made to spread rapidly at the water surface, and keep not breaking of medicine film for a long time.
Film-spreading oil solution of the present invention (Spreadingoil) is with biological organic solvent for carrier, and adds upstream face diffusant and cosolvent wherein, imposes on the film forming finish of the water surface.At present one of most labour-saving formulation in the dispenser of paddy field, in use does not need to be watered dilution, directly spreads fertilizer over the fields, have easy to use, the feature that effective rate of utilization is high.
