Description
Technical field
The invention belongs to the synergetic pesticide composition field that botanical pesticide combines with chemical pesticide, the specific one kind that provides contains
Active component epoxy worm pyridine and the synergetic pesticide composition of sophora alopecuroides extract.
Background technology
Cycloxaprid (Cycloxaprid), cycloxaprid are a kind of new neonicotinoid insecticides, belong to high-efficiency low-toxicity
Environment friendly agricultural, it is mainly used to prevent and treat pierce-suck type implication insect.According to 2 kinds of ground effect experiments of formulation 14, cycloxaprid is to Rice Brown
Plant hopper, white backed planthopper, small brown rice planthopper are efficient, also have good preventive effect to cabbage aphid and Cucumber blight, have to rice leaf roller compared with
Good simultaneous anti-effect, is significantly higher than imidacloprid to cotton field Bemisia tabaci activity.In addition, its honeybee toxicity is significantly reduced, and to pyrrole
Worm quinoline resistant insect (imidacloprid-resistant pest) is efficient.Cycloxaprid is by East China University of Science's medicine chemical industry
Research institute formulates, and has applied for Chinese patent 2 (CN 101747320A, CN 200910258534.3).
Sophora alopecuroide (Sophora alopecuroides L), also known as eel grass, belong to leguminous perennial herb, and plant is complete
Strain is poisonous, and the compounds such as aloperine and sparteine are contained in Sophora alopecuroide body.Contained alkaloid is to insect acetyl courage in Sophora alopecuroide
Alkali ester is mould obvious inhibitory action, while the respiration of insect is had a certain impact, available for killing aphid, red spider
Deng Sophora alopecuroide methanolic extract has preferable preventive and therapeutic effect to aphid.
Pea tail reparing aphid (Megoura japonica (Matsumura)), is Homoptera, Aphidiadae.It is distributed in Beijing, Ji
Woods, Liaoning, the Inner Mongol, Ningxia, Taiwan etc..Pea tail reparing aphid cause harm broad bean, pea peak period in 4~June, mainly in spray and
Cause harm on blade back, cause cauline leaf to crispatura, shortened internodes, suppress growth, influence yield.
Bean aphid (Aphis craccivora Koch), alias aphis craccivora, Aphis medicaginis, belong to Homoptera Aphidiadae, legume
Important pests.Bean aphid occurs 20 more than generation in Yangtze river basin year, winter with into, larvae aphid in beans such as broad bean, winter pea or Chinese milk vetch
Survived the winter at aphid legume lobus cardiacus or blade back.Throughout the year, when 8~10 DEG C of monthly mean temperature, bean aphid starts normally on winter host
Breeding.The first tenday period of a month in late April to May, into, that larvae aphid is clustered in reserve seed for planting Chinese milk vetch and broad bean tender tip, inflorescence, petiole, pod etc. is numerous
Grow harm；In 5 months, after the last ten-days period, with the aging of plant, produce alatae and move to summer, autumn sword bean, cowpea, French beans, peanut etc.
Parasitized breeding on legume；Late October between November, with the aging of mercury dropped and host plant, produces alatae again
Move to breeding on the winter hosts such as Chinese milk vetch, broad bean and survived the winter thereon.
The single use of agricultural chemicals can bring resistance risk, and agriculture chemical compounding is the effective way for solving resistance problem.
Develop new product bactericide is expensive, the cycle is grown, and by contrast, exploitation is efficient, less toxic, low-residual with research
Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The combination of cycloxaprid and sophora alopecuroides extract has no report.
The content of the invention
The present invention in order to for it is above-mentioned deficiency and a kind of composition pesticide containing sophora alopecuroides extract and cycloxaprid is provided,
For preventing and treating pea bean aphid, pea tail reparing aphid.
The present invention is achieved through the following technical solutions：
A kind of composition pesticide containing sophora alopecuroides extract and cycloxaprid, contains active component cycloxaprid and Sophora alopecuroide
The mass fraction ratio of extract, cycloxaprid and sophora alopecuroides extract is 30:1~1:30, it is preferably in a proportion of 15:1~1:15,
Further preferred ratio is 6:1~4:1, still more preferably ratio is 4:1 and 6:1.
The described composition pesticide containing cycloxaprid and sophora alopecuroides extract, contains active component cycloxaprid and hardship
Bean or pea extract, also contains insecticides adjuvant, and in order to be processed into insecticides adjuvant, wherein cycloxaprid and sophora alopecuroides extract is in group
Gross weight percentage composition in compound is 0.1%~60%, and remaining is insecticides adjuvant；Preferable cycloxaprid and Sophora alopecuroide extraction
The gross weight percentage composition of thing in the composition is 5%~40%, and remaining is insecticides adjuvant.
The described composition pesticide containing cycloxaprid and sophora alopecuroides extract, can be processed into aqueous suspension agent, water and milk
Agent, microemulsion.
The aqueous suspension agent formulation weight percent forms：Cycloxaprid 0.1~40%, sophora alopecuroides extract 0.1
~20%, dispersant 0.1~15%, wetting agent 0.1~10%, thickener 0.1~2%, antifreezing agent 0.1~5%, deionized water
Carrier complements to 100%；Specifically production stage is：Active ingredient and other auxiliary agents are mixed, disperseed through high speed shear, sand mill
After middle sand milling, high dispersive, stable suspension system are formed in water-medium, the aqueous suspension of corresponding weight percentage is made
Agent.
The aqueous emulsion agent weight percent forms：Cycloxaprid 0.1~20%, sophora alopecuroides extract 0.1~
10%, emulsifying agent 0.1~10%, solvent 0.1~25%, dispersant 0.1~5%, stabilizer 0.1~3%, antifreezing agent 0.1~
5%, deionized water carrier complements to 100%；Specifically production stage is：By above-mentioned active ingredient, solvent, emulsifying agent, dispersant
Oil phase is mixed to form with stabilizer, antifreezing agent dissolves in water forms aqueous phase, and oil phase is slowly added water under cutter effect
Xiang Zhong, and continue shearing 30 minutes, that is, the aqueous emulsion is made.
The micro-emulsion form weight percent forms：Cycloxaprid 0.1~25%, sophora alopecuroides extract 0.1~
15%, solvent 2-20%, stabilizer 0.1~5%, emulsifying agent 0.1~10%, antifreezing agent 0.1~3%, deionized water carrier are mended
Enough to 100%；Specifically production stage is：Active ingredient is completely dissolved with solvent, emulsifying agent, stabilizer is then added, prevents
Freeze agent to be well mixed, deionized water is eventually adding, after being sufficiently stirred, you can the microemulsion is made.
Described sophora alopecuroides extract is Sophora alopecuroide branches and leaves (dry) methanolic extract.
The extracting method of Sophora alopecuroide branches and leaves (dry) methanolic extract is：Take Sophora alopecuroide branches and leaves (dry), grinding and sieving
(40 mesh), the methanol of 2 times of quality is added, airtight heating is kept for 2 hours, filtered after being cooled to 20 degrees Celsius to 90 degrees Celsius
(100 mesh), gained filtrate decompression are concentrated into 1/5th i.e. obtained Sophora alopecuroide branches and leaves methanol for adding initial methanol quality
Extract.
The described composition pesticide containing sophora alopecuroides extract is applied to preventing and treating pea tail reparing aphid, pea bean aphid, can also
