Abstract
The invention discloses an insecticide composition which comprises the following components: 1 to 50 percent of thiacloprid, 6 percent to 80 percent of chlorfenapyr, 2 percent to 12 percent of a dispersant, 1 percent to 6 percent of a wetting agent, 2 percent to 6 percent of a disintegrant, 1 percent to 5 percent of astragalus polysaccharide, 1 percent to 5 percent of carboxymethyl cellulose sodium and the balance of carrier. The carrier is plateau soil or bentonite. The synergistic insecticide composition disclosed by the invention is suitable for preventing and treating piercing-sucking mouthpart pests on rice, vegetables, fruit trees, flowers, lawn and the like. Compounding of two effective ingredients of the insecticide composition has an obvious synergistic effect and improves preventing and treating effects; the use amount of the pesticide is reduced, and popularization and application of the insecticide composition have relatively large economic benefits and social benefits.
Description
Technical field:
The present invention relates to the preparation method of Pesticidal combination, a kind of preparation method of the Synergistic insecticidal compositions that contains thiacloprid and capillary specifically, for preventing and treating the suckings pest such as paddy rice, vegetables, fruit tree, flowers, lawn.
Background technology:
Thiacloprid is a kind ofly new sucking pest to be had to efficient broad spectrum pesticide, and different according to crop, insect and method of application, its consumption is 50.4~100.8g a.i./hm2.Field trial shows, thiacloprid has excellent control efficiency to the important pests on tea tree, pomaceous fruits fruit, cotton, vegetables and potato.Except to aphid, aleyrodid, thrips effectively, it to various beetles (as colorado potato beetle, apple weevil, Lissorhoptrus oryzophilus Kuschel) and lepidoptera pest as the leaf miner on apple tree and codling moth also effective, and corresponding all crops are all suitable for.
Thiacloprid acts on nicotinic acid acetylcholinergic receptor.It and common insecticides do not have cross resistance as pyrethroid, organic phosphates and carbamates, thereby can be used for resistance management.Thiacloprid has interior absorption and has acute contact toxicity and stomach poison function.The soil half life period of thiacloprid is short, to birds, fish and multiple beneficial arthropods safety.It is very safe to honeybee, at flowering phase of crop, can use equally.Due to thiacloprid low toxicity, efficient, by numerous users, liked.
Capillary is new pyrrole class Insecticidal and acaricidal agent.Various pests, mite are had to stomach toxicity and action of contace poison, to crop safety, be applicable to prevent and treat brassicaceous vegetable diamond-back moth, beet armyworm, tea tree tea lesser leafhopper, looper, mite, citrus red mites etc., have the advantages such as preventive effect is high, the lasting period is long, dosage is low.
In recent years, the sucking pest on crops is caused harm seriously, and peasant uses the medicines such as Imidacloprid, Biphenthrin, chlopyrifos to produce serious resistance for a long time, occurs strengthening dosage, the poor problem of control efficiency, and it is serious that environmental pollution is also tending towards.
Being mixed of different pesticide species is the common methods of the agriculture resistant insect of control.By formulation of pesticide, screening, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the generation of pest resistance to insecticide, extend the service life of medicament, is the important means of integrated pest management.The inventor is on the basis of a large amount of indoor virulence screenings and field medicine effect test, and discovery thiacloprid and capillary are mixed the suckings pest such as aphid are had to synergistic function.
Water dispersible granular is disintegration dispersion rapidly in water, forming can be for suspension or the solution of spraying, its major advantage is without dust or there is few dust to produce when producing and using, to using and producer's safety, and have the advantage of aqueous emulsion and wetting powder concurrently, thereby become the fashion trend formulation of the most potential on international market and development prospect.
Summary of the invention:
The object of the invention is to overcome the shortcoming existing in prior art, provide using method simple, the object of the invention is of using is mixed different thiacloprid and the capillaries of the mechanism of action, make full use of the synergistic effect that both are mixed and produce, provide a kind of efficient, low toxicity, agricultural insecticide composition cheaply, for preventing and treating the suckings pest such as paddy rice, vegetables, fruit tree, flowers, lawn.
Technical scheme of the present invention:
A Pesticidal combination, is characterized in that, comprises following component:

Or, comprise following component:
Thiacloprid 1~30%, capillary 6%~40%, dispersant 2%~6%, wetting agent 1%~3%, disintegrant 2%~4%, astragalus polyose 1%~3%, sodium cellulose glycolate 1%~2%, surplus are carrier.
Described carrier is upland soil or bentonite.
The preparation method of Pesticidal combination, take thiacloprid and capillary as active ingredient, and in composition, the weight percentage of thiacloprid is 1~50%, the weight percentage of capillary is 5%~80%.
Pesticidal combination of the present invention adds suitable auxiliary agent to make water dispersible granules.
Described auxiliary agent is: dispersant 2%~12%, wetting agent 1%~6%, disintegrant 2%~6%, adhesive 1%~5%, sodium cellulose glycolate 1%~5%, surplus are carrier.
Wherein, dispersant is selected from one or more in alkylbenzenesulfonate, two naphthyl sulfonate, acrylic acid polymers sodium salt, ethoxylated dodecyl alcohol; Wetting agent is selected from lauryl sodium sulfate, pulls open powder, one or more in wetting and penetrating agent F, spaonin powder; Disintegrant is selected from one or more in bentonite, ammonium sulfate, aluminium chloride, citric acid, succinic acid, carbonic hydroammonium; Carrier is selected from one or more in kaolin, diatomite, white carbon.
Its preparation method carries out as follows.
(1) thiacloprid 1~50%, capillary 6%~80%, dispersant 2%~12%, wetting agent 1%~6%, disintegrant 2%~6%, astragalus polyose 1%~5%, sodium cellulose glycolate 1%~5%, surplus are carrier; Except astragalus polyose, other raw material mixes and obtains mixture.
(2) mixture after carrying out ultramicro grinding, airslide disintegrating mill is obtained to female powder.
(3) the female powder obtaining after ultramicro grinding is taken to certain amount and put into revolving fluid bed.
