Description
Technical field
The invention belongs to pharmaceutical arts, are related to a kind of composition containing Nylar and decis, combination of the invention
Object can be effectively used for the pests such as prevention and treatment thrips, aleyrodid, aphid, housefly, mosquito.
Background technique
Since the breeding amounts such as important agricultural insect thrips, aleyrodid, aphid and sanitary insect pest housefly, mosquito, cockroach are big and from generation to generation
Overlapping is obvious, the phenomenon that pharmacy control efficacy generally reduces occurs to the prevention and treatment of these pests.Moreover, because single and not scientific use
Medicine causes drug cost to significantly improve, environmental pollution and the destruction of ecological environment etc..By two kinds of different structures, different role machine
The ingredient of reason is compounded, and is to reduce and delaying drug resistance pest, the effective way for expanding prevention and treatment target, improving drug effect.
Nylar is that phenylate class upsets the insect growth regulator, IGR of insect growth, belongs to the new type disinsection of juvenoid
Agent, have interior suction transfer activity, low toxicity, lasting period it is long, to crop safety, it is small to eco-environmental impact, to thrips, pear sucker,
Bemisia tabaci, scale insect, diamondback moth, beet armyworm, prodenia litura, pear psyllid etc. have good control efficiency, while this product pair
The sanitary insect pests such as fly, mosquito have good control efficiency.Decis, which has, tags and stomach poison function, action of contace poison are fast
Speed knocks down that power is strong, insecticidal spectrum is wide, effective to various pests such as Thysanoptera, Homoptera, Diptera, Lepidoptera, coleopteras.
Inventor has carried out the pharmacodynamic test of the composition of a large amount of Nylars and decis, it was found that many unexpected
Effect.The invention improves drug effect and expands prevention and treatment target, is conducive to reduce times for spraying, reduces drug cost.
Summary of the invention
The object of the present invention is to provide a kind of energy delaying drug resistance pests, the one kind for expanding prevention and treatment target, improving control efficiency
Composition and its application containing Nylar and decis.
Composition containing Nylar and decis, the insecticidal active ingredient in composition are Nylar and bromine cyanogen chrysanthemum
Ester, mass parts ratio 1:10-10:1, it is preferred that mass parts ratio 1:4-6:1.
Above-mentioned composition is processable to be configured to microemulsion, aqueous emulsion, suspending agent, water dispersible granules, wettable powder, particle
Agent etc., processing method are the formulation preparation method of this field routine.
Composition of the invention is for preventing and treating agricultural pests and sanitary insect pest.
Controlling object of the invention be Thysanoptera, Homoptera, Diptera, coleoptera, Lepidoptera pest.Preferably, evil
Worm be Thysanoptera, Homoptera, Diptera pest, it is further preferred that pest be thrips, aleyrodid, aphid, scale insect, housefly,
One of Culex pipiens pallens is a variety of.
Composition pesticide of the invention compared with prior art, generate it is following the utility model has the advantages that
(1) composition is obvious to synergistic effects such as pest thrips, aleyrodid, aphid, scale insect, housefly, Culex pipiens pallens；
(2) since the mechanism of action of composition active constituent is different, according to pest resistance insecticide theory and practice, composition
Using the resistance development that can delay pest, prolong its service life.

Effect of the composition of 6 pyriproxyfen-containing of embodiment and decis to cowpea thrips
Medicament is configured to microemulsion according to trial test, is tested using infusion process.Pick the biggish cowpea of thrips worm amount
Beans blade counts.Blade is soaked 2 seconds in the medicament diluted respectively, after taking-up is dried, is put into the culture dish of moisturizing, if
Leaching clear water is blank control, and every concentration is repeated 3 times.Handle (25 ± 1 DEG C, the 12H/12H) raisings of Hou Fang observation ward.It inspects periodically dead
Number is died, calculates corrected mortality with Abbott formula.Data statistics is carried out according to the following formula.Appliance computer program is found out respectively
For trying single dose lethal concentration of 50 LC50, the co-toxicity coefficient (CTC value) of mixed medicament is calculated according to Sun Yunpei's Method, CTC value is greater than 120
It is synergistic effect.Circular is as follows:
A kind of single dose (A) is set as standard single dose, specifying its toxicity index (TI) is 100, then:
Percentage of the theoretical toxicity index (TTI) of mixture=each single dose of Σ TI × single dose in mixture
1 Nylar of table compounds the virulence result to cowpea thrips with decis

Effect of the composition of 8 pyriproxyfen-containing of embodiment and decis to mango thrips
According to scheme, medicament is configured to by aqueous emulsion according to trial test, and carry out activity preliminary experiment.It is pre- according to determination of activity
Preparation is configured to the concentration needed by test.Before test, setting cell, listed, the radix of investigation mango thrips, and set corresponding
Single dose and blank control, using manual sprayer regular constant spray.7d investigates medicament to the effect of mango thrips after medicine.It uses
Percentage is converted into preventive effect by Abbot formula.
In theoretical effect, the effect for the substance A that x is concentration when being a, the effect for the substance B that y is concentration when being b compares reason
By effect and actual effect, the synergistic effect of composition is evaluated.It the results are shown in Table 3.
Effect of the composition of 3 pyriproxyfen-containing of table and decis to mango thrips
As seen from Table 3, Nylar and decis 3 proportion compositions are above reason to the practical decline rate of mango thrips
By decline rate, illustrate that Nylar is compounded with decis, having in above-mentioned 3 proportions good has synergistic effect.
In addition, testing the present embodiment 3 compoundings with when corresponding single dose to Cucumber blight, citrus scale insect, light color library
The effect of mosquito, it is found that the compounding effect of 3 proportions shows apparent synergistic effect.
The composition of 9 pyriproxyfen-containing of embodiment and decis is to housefly indoor pharmacodynamic test
Medicament is configured to microemulsion according to trial test, is tested using glass box method.Room is put before every glass box test
Interior 3~4 age in days adult housefly of emergence 100 or so, spray amount 2mL for connecting generation raising throughout the year, start timing after having sprayed, from family
Different time points test worm is recorded when fly starts to occur knocking down phenomenon knocks down number, and every processing is repeated 3 times, counts and calculate KT50, it is dead
Die rate.
Effect of 4 compounding agent of table to housefly
Nylar is compounded with decis is shown in Table 4 to the effect of housefly, it is found that under same spray concentration, Nylar
