Abstract
The invention relates to an insecticide composite with thiacloprid and butylene fipronil, belonging to the field of desinsection, and the composite is combined by the thiacloprid and the butylene fipronil. The insecticide composite has obvious synergistic effect, and is mainly used for controlling rice fulgorids, vegetable thrips and other piercing and sucking type pests.
Description
Technical field:
The invention belongs to technical field of pesticide, be specifically related to a kind of Pesticidal combination of forming by thiophene worm quinoline and butene-fipronil.
Technical background:
Chloro nicotinoids or anabasine insecticide Imidacloprid are to be used to prevent and treat one of the most effective pesticide active ingredient of piercing mouth parts and some biting mouth parts insects in 10 years in the past on the agricultural.Thereby Bayer farmingization company and Japanese Bayer farmingization company have carried out the extensive studies cooperation in development, and U.S. Bayer farmingization company has found another insecticide thiophene worm quinoline of this class formation.Thiophene worm quinoline is a kind ofly new sucking insect to be had broad spectrum pesticide efficiently, and according to crop, insect and method of application difference, its consumption is 48～180g a.i./hm
2Field trial shows that thiophene worm quinoline has excellent preventive effect to the important pests on pomaceous fruits fruit, cotton, vegetables and the potato.Except that to aphid and aleyrodid effectively, it is also effective to leaf miner and codling moth on various beetles (as colorado potato beetle, apple blossom weevil, Lissorhoptrus oryzophilus Kuschel) and lepidoptera pest such as the apple tree, and corresponding all crops all are suitable for.
The same with Imidacloprid, thiophene worm quinoline also acts on the nicotinic acid acetylcholinergic receptor.It and common insecticides such as pyrethroid, organic phosphates and carbamates do not have cross resistance, thereby can be used for resistance management.Thiophene worm quinoline has interior absorption and acute contact toxicity and stomach poison function is arranged.The soil half life period of thiophene worm quinoline is short, to birds, fish and multiple beneficial arthropods safety.It is very safe to honeybee, also can use at flowering phase of crop.Because its lower mammalian toxicity, thiophene worm quinoline is to operator and consumer safety.

Thorns suction class pests such as China's south rice growing area rice fulgorid, thrips were the large tracts of land generation in recent years, the peasant generally uses medicines such as Imidacloprid, Acetamiprid at thorns suction class pests such as preventing and treating rice hoppers, thrips, thereby caused insect that said medicine has been produced pesticide resistance serious, the pollution of environment also has been tending towards serious.Adopting two kinds of new component medicines to advance composite control resistant insect, is present comparatively desirable controlling way.
Water dispersion granule is disintegration dispersion rapidly in water, forming can be for the suspension or the solution of spraying, do not have dust when its major advantage is production and use or have few dust to produce, 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 and development prospect in international market.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that present control resistant rice plant hopper, thrips and thorn are inhaled class pest, providing a kind of is active ingredient with thiophene worm quinoline and butene-fipronil, and preparation is efficient, low toxicity, environment amenable environmental-pollution insecticide.
Purpose of the present invention realizes by following technology:
A kind of thiophene worm quinoline and butylene fipronil water dispersible granule, the percentage by weight of each component is in the prescription: thiophene worm quinoline 1%～70%, butene-fipronil 5%～80%, dispersant 1%～12%, wetting agent 1%～6%, disintegrant 1%～6%, adhesive 1%～5%, stabilizing agent 1%～5%, carrier supply 100%.
Wherein, dispersant is selected from one or more in alkylbenzenesulfonate, two naphthyl sulfonate, acrylic acid polymers sodium salt, the ethoxylated dodecyl alcohol;
Described wetting agent is selected from lauryl sodium sulfate, draws back powder, among the wetting and penetrating agent F, spaonin powder one or more;
Described disintegrant is selected from one or more in bentonite, ammonium sulfate, aluminium chloride, citric acid, succinic acid, the carbonic hydroammonium;
Described adhesive is selected from one or more in polyethylene glycol, polyvinyl alcohol, the polyvinylpyrrolidone;
Described carrier is selected from one or more in kaolin, diatomite, the white carbon;
Above-mentioned formulation material is mixed, pulverize,, add then and carry out granulation, drying, screening in the fluidized bed prilling dryer after sample analysis is made water dispersible granules product of the present invention through mediating with micro jet.
The present invention has following advantage:
1, it is remarkably productive that the present invention prevents and treats resistant rice plant hopper, thrips and leafhopper, and the wetting powder drug effect can improve 15%～20% relatively;
2, the wetting powder dust is fewer relatively, to producing and user's safety;
3, do not contain organic solvent among the present invention, environmental pollution is little, is convenient to accumulating and use;
4, preventive effect of the present invention is compared single agent and is had obvious synergistic effect.
