Composition pesticide of the present invention (former medicine content is lower than 25mg/kg) under low concentration has inhibition evil mite to cast off a skin, suppress the effect that the evil mite lays eggs: slightly high concentration (former medicine content is higher than 37mg/kg) just has well tagging property, the interior absorption simultaneously had, but can not be mixed with basic agent while using.After spraying this product, 20 minutes two spotted spider mite stop harm, the adipogenic effect of the inhibition that two spotted spider mite has been had, tagging property to young mite is best, just can reach 80.67% lethality at 24 hours, male and female become mite death slow, just there will be peak mortality in the time of 5 days, the lethality that can only reach 83.12%, 7d according to test data demonstration 5d lethality can reach 96.88%.Due to the specific functional groups in composition, can strengthen assimilation, make the fruit pol that crop is born strengthen, maximum can be increased to 15 pols, has the Associative nitrogen fixation effect simultaneously, strong plant.Quick-acting obviously is better than tetronic acid class miticide, and the lasting period slightly is longer than tetronic acid class miticide, is a kind of good oranges and tangerines miticide.
The present invention has following advantage and useful technique effect:
1. kill mite and compose wide, strong adaptability
Fluorine mite piperazine all has fine preventive effect to panonychus citri, rust Pi lice, yellow tea mite, Tetranychus cinnabarinus and Tetranychus urticae evil mite, and the mite evil that can be used for citrus, grape fruit tree and eggplant, capsicum, tomato solanaceous crops is administered.In addition, fluorine mite piperazine has the well double effect of controlling to pear sucker, oystershell scale and leafhopper class insect.
2. double the killing of ovum children
The ovicidal effect is excellent especially, if the children mite is also had to good action of contace poison simultaneously.Although fluorine mite piperazine can not kill female one-tenth mite quickly, female one-tenth mite is had to good sterilisation-effect.Female one-tenth mite touches the ovum produced after medicine has 96% can not hatch, and dies from late embryogenesis, although fluorine mite piperazine has, well the interior absorption of tagging property is more weak, only has the interior absorption of moderate, so spraying is wanted evenly.
3. the lasting period is long
The lasting period of fluorine mite piperazine is long, can control citrus red mite (crm) harm with 6000 times of dilutions in production and reach 40~50 days.Resistance of rainwater washing against after fluorine mite piperazine is executed on crop leaf, the spray medicine is met the normal performance that moderate rain does not affect drug effect after 2 hours.From the test of entrusting government test department, find out, the high outbreak period is 42 days in the lasting period in Guangxi, and 39 days Zhejiang lasting periods, the Sichuan lasting period is 32 days.The lasting period of non-high outbreak period control two spotted spider mite is the longest reaches 55 days, the shortest in 49 days.
4. low toxicity, low-residual, safety are good
Fluorine mite piperazine is very safe to crop under different temperature conditions, to people and animals and crop safety, low toxicity.Be suitable for nuisanceless production.Draw in the destructive testing of doing in our living survey group, dilute 150 times (100ml mono-sprayers) and can not cause any harm to flower and young fruit.The extension rate of all kinds of harmful mites of normal control is more than 6000 times.
5. mixed property is strong
Can use with existing the mixing now of most of agricultural chemicals (except strong basicity agricultural chemicals and copper agent); Mixed with existing miticide, both can improve the quick-acting of fluorine mite piperazine, be conducive to again the resistance management of mite evil.

The embodiment comparative trial
1, experimental subjects
Panonychus citri (Panonychus citri (Mc Gregor)): pick up from Horticulture Inst., Hunan Prov.'s citrus orchard, cultivate in indoor continuous generation breeding.
2, test is processed
First use the former medicine of acetone solution fluorine mite piperazine and the former medicine of tebufenpyrad, then make the single dose mother liquor with 0.1% Tween 80 aqueous solution dilution.According to the result of preliminary experiment, on the basis of above-mentioned mother liquor, the mixture of fluorine mite piperazine and tebufenpyrad and both five kinds of different proportionings is mixed with to 5 series mass concentration solution for later use with 0.1% Tween 80 aqueous solution dilution respectively.Fluorine mite piperazine dilution is 48,24,12,6,3mg/L; Tebufenpyrad dilution is 20,10,5,2.5,1.25mg/L; The mixture of fluorine mite piperazine and tebufenpyrad and both five kinds of different proportionings (the active ingredient proportioning is 16:1,11:5,1:1,5:11,1:16) dilution is 24,12,6,3,1.5mg/L.
3, assay method
Two-sided tape is sticked to slide one end, if then with the writing brush point, the children mite is provoked gently, and the mite back of the body gently is affixed on double faced adhesive tape.The slide that posts mite is placed in culture dish, and after 4 hours, with binocular magnascope microscopy, all mite foots motionless person reject with needle point.Finally will there is the mite slide to insert in the liquid prepared, shake gently several under, after 5S, take out, blot unnecessary liquid on blotting paper, slightly after airing, it is inserted in the moisturizing culture dish, in (25 ± 1) ℃ environment, cultivate, to soak not containing medicament but compare containing the processing of the Tween 80 aqueous solution of corresponding organic solvent and 0.1%.Every processing repeats for 4 times, several 30 of every reprocessing insect population.
4, data survey and statistical analysis
48h " Invest, Then Investigate " result, record total mite number and dead mite number (the writing brush point of take touches the motionless person of mite body as dead).If contrast lethality<5%, do not proofread and correct; The contrast lethality is proofreaied and correct between 5%~20%; Contrast lethality>20%, test need be reformed.
The logarithm value of drug concentration (mg/L) of take is independent variable x, and the probit value of (correction) lethality of take is dependent variable y, sets up respectively active regression equation, adopts DPS software to calculate the LC of each medicament 50reach 95% confidence limit, LC 90reach the co-toxicity coefficient (CTC) of 95% confidence limit, mixture, relatively the synergy situation.
5, interpretation of result and discussion
According to the symphyogenetic co-toxicity coefficient criteria for classifying of NY/T1154.7-2006 mixed insecticide: co-toxicity coefficient (CTC) >=120 shows as synergistic effect; CTC≤80 show as antagonism; 80<CTC<120 show as summation action.
As can be seen from Table 1: fluorine mite piperazine and tebufenpyrad all are greater than 120 at the co-toxicity coefficient of 5 kinds of proportioning mixtures such as 16:1,11:5,1:1,5:11 and 1:16, show as synergistic effect.
