Description
Technical field
The present invention relates to a kind of insecticide acaricide composition having and improving performance, concretely relate to one and comprise acrinathrin and azoles demodicid mite
The insecticide acaricide composition of ester, belongs to field of pesticide preparation.
Background technology
Acrinathrin (acrinathrin) belongs to efficiently, low toxicity, wide spectrum, novel pyrethroid mite killing, insecticide.
Multiple planting property of food evil demodicid mite is agree have good activity, and to sucking insect and lepidoptera pest, as wood louse, leaf miner,
Thrips, aphid etc. also have good activity.For Cotton Gossypii, fruit tree, Semen sojae atricolor, Semen Maydis, vegetable, Folium Camelliae sinensis, Fructus Vitis viniferae, Citrus chachiensis Hort.
The crop such as Fructus Citri tangerinae, Nicotiana tabacum L..
Fenpyroximate (Fenpyroximate) be fenpyroximate be a kind of novel phenoxy group pyrazoles acaricide, unique E body knot
Structure is higher than common Z body structure acaricidal activity, speed fast, based on action of contace poison, adds the fat in suppression demodicid mite body simultaneously
The special auxiliary agent of fat synthesis.And no interactions resistance between existing acaricide, it is adaptable to resist for preventing and treating existing acaricide is produced
The pest mite class of property；.Mite killing spectrum is wide, and has the parasite killing effect of curing the disease concurrently.Mite killing speed is fast, and ovum children is double to be killed, and the lasting period is long,
Low toxicity, low-residual, safety are good.It is applicable in various plants prevent and treat tetranychus telarius and full pawl tetranychid.
There are some researches show, long-term repeated and single-minded use a kind of reactive compound and carry out pest control and will cause insect under many circumstances
Drug resistance strengthens, and for reducing pest resistance to insecticide, the most generally uses the mixture of different activities compound to carry out pest control.By having
The reactive compound of the different mechanisms of action is combined, and delaying drug resistance can produce, reduces amount of application, improves prevention effect, and reduce preventing and treating
Cost.
Summary of the invention
It is an object of the invention to: for insecticidal/acaricidal agent resistance problem in actual applications, the parasite killing filtering out two kinds of different action principles kills
Demodicid mite agent compounds, and with raising effect prevention effect, reduces formulation rate, expands range.
For achieving the above object, the invention provides one group of insecticide acaricide composition, said composition comprises two kinds of effective constituents A and B,
Active component A is acrinathrin, and active component B is fenpyroximate.Inventor is found by experiment that, above-mentioned Pesticidal combination potentiation is obvious,
Amount of application reduces, it is possible to decrease use cost.Different from the compound structure type of component B containing component A, mechanism of action is different, and two
The compounding action spectrum that can expand of person, and the generation of insect-resistant, and nothing between component A and component B can be delayed to a certain extent
Cross resistance.
Present invention offer comprises two kinds of effective constituents A and the compositions of B and it prevents and treats the application of crop pests at agriculture field.
The compositions of the present invention comprises two kinds of active components of A and B, and the weight ratio between two components is 1:30～30:1, preferred weight ratio
1:20～20:1, further preferred weight ratio is 1:10～10:1.In some embodiments, two kinds of active component A and B can
Select 9:1,8:1,7:1,6:1,5:1,4:1,3:1,2:1,1:1,1:2,1:3,1:4,1:5,1:6,1:7,1:8,1:9 etc. more
The proportioning of body.
Said composition can be aided with acceptable adjuvant on pesticide with active component and make any one dosage form of applicable agricultural use, specifically
, it can be with active component and be aided with normally used auxiliary agent in pesticidal preparations, solvent, carrier auxiliary element to make various being suitable for
The dosage form used in agricultural.
When this compositions makes a certain concrete dosage form, wherein active component mass content be 1～99%, preferably 1～90%, enter
One step preferably 5～85%, further 10～55%, most preferably 10～35%.
The compositions of the present invention can be prepared as various dosage form by available known method, can by effective ingredient and auxiliary agent,
