Description

Suspending agent of a kind of cyanogen insect amide and preparation method thereof
Technical field
The invention belongs to technical field of pesticide preparations, relate in particular to suspending agent of cyanogen insect amide and preparation method thereof.
Background technology
Cyanogen insect amide (English common name cyantraniliprole) is the second generation ryania receptor activators of the up-to-date exploitation of E.I.Du Pont Company, than chlorine insect amide the more insecticidal activity of wide spectrum is arranged.
CA registration number: 219714-96-2
Molecular formula: C 19H 14BrClN 6O 2
The structure of cyanogen insect amide (cyantraniliprole) is as follows:
Figure G2009101104878D00011
The cyanogen insect amide high-efficiency broad spectrum can very effective control be chewed class and suck class pest, and usage amount is 10-100 gram (a.i)/hectare, can prevent smelting diptera leaf mining insects, food leaf class coleoptera class, Lepidoptera class, fruit bat class, aleyrodid etc.Preliminary on probation confirm to prevent eliminating aphis, thrips, weevil, wood louse, aleyrodid, little cycle of sixty years, leaf roller, cotton leaf flea beetle etc.Cyanogen insect amide has stronger permeability, and medicament can pass stem's cuticular cellulose and enter xylem, thereby conducts to other position along xylem.The optional face spraying that gets rid of leaves of using method, drip irrigation, soil light irrigation method, seed treatment etc.Cyanogen insect amide can be used for the pest control of crops such as leguminous plant, corn, cotton, paddy rice, wheat, oat, beet, tomato, potato, eggplant coffee, citrus, brassicaceous vegetable, grape, muskmelon, improves quality and the harvest of crop.
Pesticide original medicine, except the minority volatility big or in water solvability big can directly use, all must be processed into various formulations.Common formulation has missible oil, pulvis, granule, aqueous emulsion, suspending agent etc.Especially formulation such as aqueous emulsion, suspending agent because use for environmentally friendly water as dispersion medium, greatly reduces the people of favor solvent in the regular dosage form more and more is subjected to to(for) the influence of environment.Suspending agent refers to water to be dispersant, the pesticidal preparations that pesticide original medicine and various auxiliary agent (wetting agent, dispersant, antifreezing agent etc.) are obtained through the wet method ultramicro grinding.Suspending agent can mix with arbitrary proportion with water, and is easy to use, has the advantage of wetting powder and missible oil concurrently, can reach bigger coverage rate after the dilution.Suspending agent once once was called epoch-making novel form by domestic and international pesticide industry.Be that dispersion medium makes it have environmental protection, cheap characteristics with water, do not need a large amount of auxiliary agents, production process safety, pollution-free problem simultaneously again.Suspending agent can be processed to the formulation of high concentration, and this also is one of trend of suspending agent development at present.Aspect drug effect, the suspending agent herbicide effects is better than wetting powder, and the insecticide effect is then close with missible oil.
At present as yet not relevant for the report of cyanogen insect amide related preparations.
