Abstract
The invention relates to a pesticide composition, the effective components of which are tolfenpyrad and bifenazate in a weight part ratio of 25:1-1:25. The tolfenpyrad and bifenazate compounded pesticide composition provided by the invention has an obviously increased effect on homoptera pests, increase efficiency obviously, improves the pest control effect, simultaneously expands the insecticidal spectrum, and also has a good treatment effect on mite, lepidoptera, coleopteran and thysanoptera pests.
Description
Technical field
The invention belongs to field of agricultural pesticide, be specifically related to a kind of composition pesticide that Tolfenpyrad, Bifenazate be active ingredient of take, mainly be applicable to prevent and treat homoptera pest, mite class, Lepidoptera, coleoptera, Semiptera, thrips pest had to the preferably double effect of controlling simultaneously.
Background technology
Along with progressively eliminating of high-toxic pesticide, need efficient, low toxicity, safety, environment amenable pharmaceutical preparations, the long-term use of agricultural chemicals simultaneously produces the pesticide resistance of disease pest and weed, requirement to control medicament is also more and more higher, this just needs agricultural chemicals research staff to develop the pharmaceutical preparations of highly effective and safe, meets control requirement.Because China's agricultural chemicals initiative is at the early-stage, the pesticide species with independent intellectual property right can't be satisfied the demand, so the pesticide mixed preparation of development of new, is the only way of current Agrochemicals.
The novel pyrazole heterocyclic insecticidal/acaricidal agent of Tolfenpyrad Shi Yuan Mitsubishi chemical company (its agricultural chemicals partly now belong to Japanese agricultural chemicals company) exploitation, its main mechanism is the oxidative phosphorylation that stops insect, also there is ovicidal, press down food, oviposition deterrence effect, Homoptera, thrips insect are had to special efficacy.
Bifenazate is wide spectrum organosulfur acaricide, if to becoming mite and mite to have special efficacy, can be used for preventing and treating cotton, vegetables, apple, citrus, tea, the various harmful mites of flowers and other crops, to most natural enemies securities.
Agricultural chemicals is rationally composite is to improve preventive effect, expands and kills pest scope, delays the speed of pest communities succession, reduces the resistance risk that the single use of agricultural chemicals brings, and alleviates the pollution to environment, reduces use cost and reduces residual a kind of effective ways.The inventor conducts in-depth research being mixed of Tolfenpyrad, Bifenazate, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that Tolfenpyrad, Bifenazate are mixed, within the scope of certain mixed ratio, tea lesser leafhopper is shown to synergistic function, after further study, completed the present invention.
Summary of the invention
The object of the invention is to solve the deficiency that agricultural chemicals is single while using, provide a kind of efficient, low toxicity, low cost, quick-acting good, and the lasting period is long, is conducive to the composition pesticide that tea plant pest does harm to the integrated pest managements such as mite.
Technical scheme of the present invention is: a kind of composition pesticide, by active ingredient Tolfenpyrad and Bifenazate and suitable insecticides adjuvant, formed, and the ratio of weight and number of Tolfenpyrad and Bifenazate is 25:1～1:25.
Described agricultural chemicals Herbicidal combinations those skilled in the art can, according to known method, select suitable pesticidal preparations auxiliary element, the formulation of using in the applicable agriculturals such as excipient suspending agent, wetting powder, water dispersible granules.
The processing technology of the various preparations of agricultural chemicals Herbicidal combinations of the present invention is prior art, according to different situations, can change to some extent.
The insecticides adjuvant using in agricultural chemicals Herbicidal combinations of the present invention comprises that solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, pH adjusting agent, defoamer, antifreezing agent, packing agent etc. are of value to active ingredient and in preparation, stablize and bring into play the known substance of drug effect, be all various compositions conventional in pesticidal preparations or that allow to use, concrete composition and consumption require to determine by test according to formula.
Composition pesticide provided by the invention, is mainly used in preventing and treating homoptera pest, as tea lesser leafhopper etc., mite class, Lepidoptera, coleoptera, Semiptera, thrips pest is had to the preferably double effect of controlling simultaneously.
Composition pesticide provided by the invention has following beneficial effect:
1, composition pesticide provided by the invention, expanded the scope of application of Tolfenpyrad and Bifenazate single dose, within the scope of 25:1～1:25, homoptera pest is shown to obvious synergistic function, the control efficiency of composition has had raising than single dose, reduce the using dosage of agricultural chemicals, reduced drug cost and the agricultural chemicals risk to ecotope adverse effect.
2, composition pesticide provided by the invention, can reduce the resistance risk that the single Tolfenpyrad of long-term use or Bifenazate produce, and extends the service life of medicament, the comprehensive regulation important in inhibiting to insect.
3, composition pesticide provided by the invention, has the preferably double effect of controlling to mite class, Lepidoptera, coleoptera, Semiptera, thrips pest.
Accompanying drawing explanation
Fig. 1 is the synergy equivalence line chart that Bifenazate and Tolfenpyrad are mixed to smaller green leaf hopper.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the present invention describes with following specific embodiment, but the present invention only limits to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as limitation of the scope of the invention.It should be pointed out that all any modifications of making within the spirit and principles in the present invention, be equal to replacement and improvement etc., within all should being included in protection scope of the present invention.
In these embodiments, unless otherwise indicated, all percentage is all weight percentage.
Embodiment mono-: Bifenazate and Tolfenpyrad and the toxicity test being mixed to smaller green leaf hopper thereof.
Table 1, Bifenazate and Tolfenpyrad and the regression relation being mixed to the dose-response of smaller green leaf hopper thereof.
Fig. 1, Bifenazate and Tolfenpyrad are mixed to the equivalent line chart (Fig. 1 draws with reference to NY/T1155.7-2006, and draw data derives from table 1) of the synergy of smaller green leaf hopper.
By Fig. 1 learn Bifenazate and Tolfenpyrad in 25:1,15:1,7:1,3:1,1:1,1:3,1:7,1:15,1:25 ratio to the equivalent point of tea tree smaller green leaf hopper all under theoretical equivalent line, show as synergistic function; The equivalent point line corresponding to each ratio, Bifenazate and Tolfenpyrad actual measurement equivalent line, under theoretical equivalent line, show as synergistic function to tea tree smaller green leaf hopper.
