Filtrate is collected in filtering, is removed ethyl alcohol, is obtained extract；
3) mass ratio that 200mL is added in every gram of extract is to stir 40 points in the ethyl acetate of 1:6 and the mixed liquor of water
Clock, stratification, collected organic layer, concentration.
Wormwood essential oil is made by the following method in embodiment 2-8:
1) wormwood leaf crushed, cross 30 meshes, obtain wormwood powder；The second of 40mL mass concentration 65% is added in every gram of wormwood powder
Alcohol, 70 DEG C are stirred 1 hour；Cooled and filtered collects filtrate, removes ethyl alcohol, obtains extract；
2) mass ratio that 200mL is added in every gram of extract is to stir 40 points in the n-hexane of 1:7 and the mixed liquor of water
Clock, stratification, collected organic layer, concentration.
In the embodiment of the present invention, virulence test operating method:
Using leaf pipe medicine embrane method.Prick several apertures in 4mL centrifuge tube pipe lid and tube bottom, aperture with prevent thrips from escaping for
It is quasi-.Then reagent agent is diluted with water to 5 concentration, under about 1mL medical fluid is added in centrifuge tube after reverse shaken several times
Medical fluid is outwelled, naturally dry in pipe lid rear chamber is opened；Then fresh and tender cowpea beanpod is cut with a knife into the piece that length is about 2cm
Section is placed in for naturally dry after dipping 10s in reagent liquid, is sandwiched in centrifuge tube, and suck 20 cowpea Jis with pest sucking device
It is sprung into centrifuge tube after horse (the big thrips of beans) adult；It is (25 ± 2) DEG C that centrifuge tube, which is then placed in temperature, and L:D=is arranged in illumination
Check that test worm death condition (touches polypide with small writing brush pen tip, motionless person is considered as extremely in the growth cabinet of 14h:10h, after 48h
It dies).Every pipe is 1 repetition, and every concentration is repeated 3 times.Using clear water as blank control.Virulence equation and cause are calculated with least square method
Concentration LC50, calculates the toxicity index and mixed co-toxicity coefficient (i.e. CTC value) of medicament in dead.
The synergistic effect of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), i.e. CTC≤80 are antagonism, 80 < CTC
< 120 is summation action, and CTC >=120 are synergistic effect.
Survey toxicity index (ATI)=(LC50 of the LC50/ reagent agent of standard agent) × 100；
The virulence of the percentage composition+B medicament of A medicament refers in toxicity index × mixture of theoretical toxicity index TTI=A medicament
The percentage composition of B medicament in number × mixture；
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.

1 20.4% chlorfenapyr microemulsion of comparative example
By following weight proportion:
The field control effectiveness test of the prevention and treatment thrips of embodiment 10
Experimental plot design is carried out according to China State Bureau of Quality and Technical Supervision's " pesticide field efficacy medicine test criterion (1) " standard,
Each plot area is 20m2, 40 cells are set altogether, and the isolation strip of 1.2m is set between each cell.Insecticide-applying way uses spray-on process,
With power spraye even spraying 1 time when application.
It participates in the experiment crop: cowpea
Reagent agent: embodiment 2~9, comparative example 1, clear water control.Every group of processing sets 4 repetitions.
Effective component dosage: 60g/hm2
Meteorological condition: weather is fine or cloudy, gentle breeze, and 23~32 DEG C of temperature.
Investigation method: adjusting Check insect population before application, is sampled with 5 points of every cell diagonal line, every solid point, which is seted the tone, looks into 10 plants of cowpeas
Beans simultaneously mark.The work borer population on 50 plants of cowpeas is looked into altogether.1d, 3d, 7d and 14d carry out tune Check in the same way after application,
Calculate preventive effect.
The field control effectiveness test of the prevention and treatment thrips of table 2
As the result is shown: average preventive effect reaches 82% or more after embodiment medicament application 3 days, and display embodiment medicament has speed
Effect property；Average preventive effect reaches 87% or more after embodiment medicament application 7 days, shows synergistic effect, after embodiment medicament application 14d
Preventive effect still maintains 75% or more, illustrates that lasting effect is good, wherein the quick-acting and holding effect of 7 microemulsion of embodiment 6 and embodiment
Property it is obviously preferable, application 14 days after preventive effect still reach 95%.
In the embodiment of the present invention, effective component dosage is 60g/hm2When reaches good insecticidal effect, and (inventor will
Effective component dosage is improved to 100g/hm2Shi Faxian, 1d, 3d, 7d, 14d preventive effect slightly rise), and the routine of capillary
Dosage is generally 100g/hm2(test discovery, is increased to 100g/hm for the effective component dosage of comparative example 1 for left and right2Afterwards, 1d,
3d, 7d, 14d preventive effect are still significantly lower than each embodiment medicament), it can be seen that, pesticidal preparations of the present invention not only insecticidal effect compared with
It is good, and effective component dosage is less, alleviates the influence to environment.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made.
