The influence of the extension of chemical prevention medication history, the agricultural chemicals not factor such as scientifical use, it follows that agricultural pests resistance day
Beneficial serious, the pest species for producing resistance are persistently increasing, and are one of current agricultural problems for being badly in need of solving.
Bifenazate (bifenazate) is biphenyl hydrazine acaricide, and sterling is white solid, is a kind of new selective
Foliar spray acaricide, belongs to non-internal-absorting acaricide, to each life stage of mite effectively, with ovicidal activity and into
Mite knocks down activity, influences minimum to predatory mite, is very suitable for the comprehensive regulation of insect.
Etoxazole (etoxazole) is a kind of acaricide of SUMITOMO CHEMICAL KCC research and development, belongs to diphenyl evil
Oxazoline derivative, mainly tags and stomach poison function, substantially without absorbability, ovum, young mite, deutonymph etc. can be prevented and treated, to citrus, apple
Fruits and vegetables, the tetranychid of flowers and other crops volume, Panonychus citri, Tetranychus urticae, Tetranychus cinnabarinus etc. are effectively.
A kind of miticide compositions containing etoxazole and Bifenazate of Chinese patent CN101999382A, can be configured to moisture and dissipate
Granula, suspending agent, wettable powder, dispersible oil-suspending agent, missible oil, aqueous emulsion or micro-emulsion form, to citrus, apple tree,
Cotton red spider has preferable prevention effect.
Chinese patent CN104054732A discloses a kind of agricultural acaricides aqueous suspension agent composition, specifically comprising etoxazole
And Bifenazate, the preventive effect to tetranychid can be effectively improved.
Chinese patent CN105613542A discloses a kind of Synergistic mite killing composition containing etoxazole and Bifenazate, formulation
For suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wettable powder, ultra low volume liquids, microcapsule suspending agent etc., with association
Same synergistic effect, usage amount is few, cost is low, for preventing and treating Panonychus citri, Tetranychus urticae, the section shapes such as field crop, water fruits and vegetables
Tetranychid, Tetranychus cinnabarinus etc..
Although prior art discloses Bifenazate and the compound of etoxazole, but the research of this respect only resides within association
With synergy aspect, namely by indoor or field experiment, composition is determined relative to the virulence or preventive effect of single dose, is not carried out more
Profound research or improvement, prior art is never concerned about or paid attention to the effective rate of utilization after pharmacy application, for example, penetrates evil
The dose of mite body surface, which results in unnecessary waste.

(Two)Evil mite body surface penetration test
1st, citrus tetranychid is tested
For examination evil mite:Citrus tetranychid (Panonychuscitri)
Reagent agent and comparison medicament:Bifenazate, etoxazole;Cyflumetofen
For examination synergist and control auxiliary agent:N-380;NF-100(A kind of glycosyl modified organic silicon auxiliary agent), penetrant t
Test method:
Bifenazate and etoxazole compound that total concentration is 5000mg/L are prepared with ethyl acetate(Bifenazate:Etoxazole=1:
15)Mother liquor, and the cyflumetofen mother liquor that concentration is 5000mg/L, it is standby.
A certain amount of synergist N-380, and control auxiliary agent NF-100 and penetrant t are weighed respectively, and each personal distilled water is matched somebody with somebody
Concentration is made and is 50 mg/L solution, and is divided into several pieces.According to the experimental design of such as table 1 below, divide into the solution prepared
The a certain amount of mite killing medicament mother liquor prepared in advance is not added, is 400mg/L to drug concentration.Mite killing medicament is with increasing in each solution
The weight ratio for imitating agent is 8:1.
Select citrus tetranychid nymph of the same size.Take dactylethrae some, 100 nymphs are placed in each dactylethrae, so
Each processing solution 5ml prepared is each added afterwards, dactylethrae is then fixed on shaking table, and keeps gently rocking.1 hour
Afterwards, solution in dactylethrae is outwelled, and cleans with ethyl acetate deutonymph surface 3 times, to clean the medicament of deutonymph surface remaining.
Using improved QuEChERS extraction methods, it is put into centrifuge tube, adds after the deutonymph of clean epidermis medicament is smashed to pieces
2ml ethyl acetate, is vortexed uniform 2 minutes, stands 10 minutes;Then 3000 revs/min centrifuge 10 minutes, take supernatant, addition contains
Anhydrous sodium sulfate and primary secondary amine(PSA)Centrifuge tube in, be vortexed uniform 10 seconds, 3000 revs/min centrifuge 10 points
Clock, membrane filtration is closely dry by supernatant concentration, and with 1ml ethyl acetate constant volumes, the pesticide concentration in sample is detected with GC.Often
Handle 3 repetitions.As a result it see the table below 1.
The infiltration capacity of each treatment agent of table 1
The above results are not difficult to find out that synergist N-380 can substantially increase Bifenazate and etoxazole compound penetrates evil mite body
The amount of table, infiltration capacity is 4.21 μ g, is far longer than infiltration capacity when addition NF-100 and penetrant t.But, synergist N-380
To the osmotic effect of comparison medicament cyflumetofen when adding NF-100, penetrant t compared with, substantially increase is not observed.
2nd, apple tetranychus are tested
For examination evil mite be apple tetranychus (Panonychusulmi)
Remaining test method is tested with citrus tetranychid.As a result 2 be see the table below.
The infiltration capacity of each treatment agent of table 2
The above results are not difficult to find out that synergist N-380 can substantially increase Bifenazate and etoxazole compound penetrates evil mite body
The amount of table, infiltration capacity is 3.95 μ g, is far longer than infiltration capacity when addition NF-100 and penetrant t.But, synergist N-380
To the osmotic effect of comparison medicament cyflumetofen when adding NF-100, penetrant t compared with, substantially increase is not observed.
Examples detailed above is only that the present invention is explained further, and is not limitation of the invention, by by above-mentioned side
Case carries out simply adjusting the scheme obtained from, equally within the protection domain of the application.
