A kind of containing double third ring worm esters and the composite insecticide of ethofenprox and applicationTechnical field
The present invention relates to the prevention and control field of insect, particularly relate to a kind of containing double third ring worm ester and composite insecticidals of ethofenproxAgent and application thereof.
Background technology
Bemisia tabaci is a kind of quarantine pest, has started since coastal area from 2003, and area expands rapidly, dangerEvil degree increases the weight of year by year.Bemisia tabaci has become the restriction yield of commercial crops such as booth Capsicum annuum L., Fructus Solani melongenae and quality improves one hinders greatlyHinder.Bemisia tabaci is mainly manifested in 3 aspects to the hazardness of crops: one is to inhale plant juice by sucking mouth parts thorn and makeKilled plant leaf chlorisis, turning yellow, wilt, even Herb is withered；Two is the viral disease that spreads disease, and Bemisia tabaci can be propagated and plant virus more 30Disease, causes virosis extension to spread；Three be Bemisia tabaci adults, nymph secretion honeydew can induce the fungal diseases such as sooty mould, press downFabrication photosynthesis, reduces yield and quality, and the most due to illness the field that insect density is high is ruined Seedling, even had no harvest.
For a long time, the preventing and treating of Bemisia tabaci relies primarily on imidacloprid, avilamycin, Buprofezin, pymetrozine, Nitenpyram etc.Single insecticide, has produced obvious Drug resistance, and prevention effect drastically declines, and therefore, research and development efficiently prevent and treat Bemisia tabaciComposite insecticide kind is to tackle its drug-fast problem, it has also become the task of top priority.
Currently also there is the research of some composite insecticides, but be both for the broad spectrum insecticide of various pests, actualThe insecticidal effect of upper special reply Bemisia tabaci is not very well, according to life habit and the medicine resistance ability of Bemisia tabaci, specializes inGo out a kind of worth discussion of composite insecticide for Bemisia tabaci with good result.
Summary of the invention
Goal of the invention: in order to overcome the preventing and treating of Bemisia tabaci present in prior art to there is obvious Drug resistance, preventing and treating effectThe problem that drastically declines of fruit, the present invention propose a kind of Bemisia tabaci is controlled effective, reduce dosage, reduce environmental pollution andThe residual of agricultural product, lasting period length and delay drug-fast containing double third ring worm ester and ethofenprox to single insecticide of Bemisia tabaciComposite insecticide and application.
Technical scheme: in order to solve above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of containing double third ringsWorm ester and the composite insecticide of ethofenprox, by weight by the auxiliary agent of main component, 5%～30% of 5%～60% and remainingThe carrier composition of amount；Wherein said main component includes double third ring worm ester and mixing of ethofenprox that weight ratio is 1:50～50:1Thing.
Being more highly preferred to, the dosage form of described composite insecticide is in water dispersible granules, wettable powder, aqueous emulsionKind.
Being more highly preferred to, described auxiliary agent is emulsifying agent, wetting agent, stabilizer, dispersant, thickening agent, defoamer, ph regulationAgent, filler.
Being more highly preferred to, the dosage form of described composite insecticide is water dispersible granules, and main component percentage by weight is 24%,Concrete component is: 8g double third ring worm ester, 16g ethofenprox, 4g sodium lauryl sulphate, 2g polyoxyethylene lauryl ether, 2g is woodenElement sulfonate, 2g sulfonic acid polyformaldehyde condensation substance, 2g Polyethylene Glycol, 4g ammonium sulfate, 10g sodium carboxymethyl cellulose, Kaolin are mended extremely100g。
Being more highly preferred to, the dosage form of described composite insecticide is wettable powder, and main component percentage by weight is 36%,Concrete component is: the double third ring worm ester of 12g, 24g ethofenprox, 4g sodium lauryl sulphate, 4g sodium lignin sulfonate, 2g pull open powder,Kieselguhr complements to 100g.
Being more highly preferred to, the dosage form of described composite insecticide is aqueous emulsion, and main component percentage by weight is 24%, specificallyComponent is: 8g double third ring worm ester, 16g ethofenprox, 10g dimethylbenzene, 5gN-methyl pyrrolidone, 2g alkyl benzene calcium sulfonate, 6g benzeneEthyl phenol mela mine-formaldehyde resin polyoxyethyl ether, 4g ethylene glycol, 0.4g silicone compound, 0.1g xanthan gum, 0.8g aluminium-magnesium silicate, waterMend to 100g.
The invention allows for above-mentioned containing double third ring worm esters with the application of the composite insecticide of ethofenprox, specifically for cigaretteThe preventing and treating of aleyrodid.
It is more highly preferred to, above-mentioned containing double third ring worm esters with the application of the composite insecticide of ethofenprox, for every mu of crop,The consumption of composite insecticide is 25g/ mu.
Beneficial effect: it is a kind of containing double third ring worm esters and the composite insecticide of ethofenprox and application that the present invention provides,For the life physiological habit of Bemisia tabaci, and the different insecticidal mechanisms of various medicament, its perfect adaptation is got up, it is suitable to be aided withAuxiliary agent and carrier, seek most suitable proportioning and Bemisia tabaci prevented and treated, with tradition water prevention and controls compared with have followingAdvantage: a) this kind has obvious potentiation to Bemisia tabaci compared with single dose, is remarkably improved prevention effect；B) can replaceFor poison insecticide high in part, reduce dosage, reduce environmental pollution and the residual of agricultural product；C) Bemisia tabaci can be delayed singleThe Drug resistance of insecticide；The advantage d) with lasting period length, compared with single medicament, it is possible to decrease cost.
