Description

A kind of Pesticidal combination containing Herba Polygoni hydropiperis
Technical field
The present invention relates to agricultural insecticide compositions and application thereof, a kind of Pesticidal combination containing Herba Polygoni hydropiperis.
Background technology
Metaflumizone belongs to semicarbazones insecticides, and Main Function mechanism is that it is attached to the receptor of sodium-ion channel On, hinder sodium ion to pass through, and then suppression neural impulse makes polypide excessively loosen, benumbs, after several hours, insect stops taking Food, dead in 1 to 3 days.This medicament mainly kills off the insect pests with stomach poison function, and action of contace poison is less, without systemic action.It can have Effect ground prevents and treats each Species of Lepidopterous Insect Pests and the larva of some coleoptera, adult, it is also possible to be used for preventing and treating Formica fusca, Coptotermes formosanus Shtrari., flies, Cicadae The insects such as dung beetle.To mammal impassivity toxicity, low to the acute toxicity of birds, danger low to Apis, owing in water, energy is fast Hydrolyze and photodissociation fastly, aquatile is endangered without reality.
Press down food hydrazine, be a kind of novel insect growth regulator, IGR, main by reducing or the taking food of suppression larva and adult Ability, promotes insecticide to accelerate to cast off a skin, and minimizing is laid eggs, and hinders insect reproduction, is finally reached the purpose of parasite killing.To insect mainly with stomach Toxic action is main, and insecticidal spectrum is wide, and Lepidoptera, Diptera and coleopteran pest are had good prevention effect, and quick-acting is poor, After dispenser 2-3 days take effect, and the lasting period is longer.
Herba Polygoni hydropiperis (formal name used at school is Polygonum hydropiper), calls as Herba Polygoni hydropiperis, Herba polygoni hydropiperis, rose, anxiety knotweed, rose knotweed, rose anxiety, pool Knotweed, pungent dish, knotweed bud vegetable, be a kind of polygonaceae plant, also referred to as Herba polygoni hydropiperis.
At present, not yet there is metaflumizone and press down food hydrazine and Herba Polygoni hydropiperis extracting solution compositions report in terms of parasite killing.
Summary of the invention
It is an object of the invention to provide a kind of Pesticidal combination containing Herba Polygoni hydropiperis, said composition has synergistic function.
Technical scheme: a kind of Pesticidal combination containing Herba Polygoni hydropiperis, effective ingredient is metaflumizone and presses down food hydrazine and Herba Polygoni hydropiperis extraction Liquid, metaflumizone and press down food hydrazine and Herba Polygoni hydropiperis extracting solution weight ratio in the composition be 1:1:1.
Metaflumizone and press down food hydrazine and Herba Polygoni hydropiperis extracting solution gross weight percentage composition in the composition be 6～60%.
The auxiliary element used in the present composition includes solvent, cosolvent, emulsifying agent, wetting agent, disintegrating agent, stablizes Agent, dispersant, thickening agent, penetrating agent, pH adjusting agent, synergist, defoamer, antifreezing agent, carrier etc. are of value to effective ingredient and exist Stable and the known substance of performance drug effect in preparation is all conventional in pesticidal preparations or allows the various compositions used, and specifically becomes Divide and consumption is determined by test according to recipe requirements.
The dosage form of Pesticidal combination is suspending agent, aqueous emulsion, microemulsion, cream, wettable powder, water dispersible granules.
Frequency of administration and the amount of application of the present composition have small variations with crops, insect, weather condition change, The purpose effectively prevented and treated can be reached by using suitable dosage.
Compared with prior art, it is an advantage of the current invention that.
1, the present invention has synergistic function, is used alone than each single dose and significantly improves the effect of the preventing and treating to insect Really.
2, the mechanism of action of the present invention is different, can delay the generation of pest resistance to insecticide.
3, The present invention reduces the usage amount of effective ingredient, reduce use cost, decrease the pollution to environment simultaneously.

1, the indoor joint toxicity measuring to diamondback moth.
For examination worm: indoor diamondback moth 3 instar larvae for many generations raising health.
Reagent agent: A uses the 96% former medicine of metaflumizone, and B uses 95% to press down the food former medicine of hydrazine, and C uses 90% Herba Polygoni hydropiperis to extract Liquid.
Test method: use folder poison blade method to be measured, specific as follows.
First beat with the card punch of diameter 1cm and take leaf butterfly, put into culture dish, moisturizing.Then will be each with capillary tube dropper Treatment agent is from the beginning of low concentration, and every leaf butterfly drop 1ul medicinal liquid, after solvent volatilizees and another sheet scribbles the leaf butterfly pair of gelatinized corn starch Folder poison leaf butterfly is made in conjunction, makes in the complete hole being put in 12 hole tissue culturing plates.Last tissue culturing plate connects 1 examination in each hole Worm, is placed in temperature 27 ± 1 DEG C, in relative humidity is the intelligent insectary of 70%.Connecing worm 2～after 4 hours, worm to be tried has taken food and has contained After medicine leaf butterfly, in cultivating plate hole, add clean feeds continue to raise to investigation, eliminate the examination worm not eaten a complete leaf butterfly. Often process and set 4 repetitions, often repeat no less than 12 folder poison leaf butterflies, and the process setting the corresponding organic solvent without medicament is made For comparison.After process, 72h investigation examination worm death condition, records total borer population and dead borer population.
Carry out statistical analysis with DPS statistical analysis software, calculate the LC of each medicament50, and calculate mixture according to the abundant method of Sun Yun Co-toxicity coefficient (CTC value).
Actual measurement toxicity index (ATI)=(standard agent LC50/ reagent agent LC50)×100。
Percentage composition+B medicament the toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed The percentage composition of B in agent.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] × 100.
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as Potentiation；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficient (CTC) ＜ 120 show as being added and make With.
Table 1, indoor joint toxicity measuring to diamondback moth.
2, the field control effectiveness test to diamondback moth
This embodiment is used for preventing and treating Caulis et Folium Brassicae capitatae diamondback moth, investigates insect population radix before dispenser, and after medicine, 3d, 7d, 10d investigate residual respectively Borer population alive, investigation Shi Mei community is stayed to carry out by diagonal 5 point sampling, every some residual diamondback moth larvae looked on 2 strain Caulis et Folium Brassicae capitataes, note Carry borer population of living, calculate prevention effect.Prevention effect computational methods are as follows.
Prevention effect (%)=(1-CK1×Pt1/CK2×Pt2)×100.Wherein: CK1Represent insect population number before the medicine of check plot； Pt1Represent insect population number after treatment region medicine；CK2Represent insect population number after the medicine of check plot；Pt2Represent insect population number before treatment region medicine.
Table 2 respectively processes the result of the test of chemical control Caulis et Folium Brassicae capitatae diamondback moth.
In sum, the present invention adopts compositions, has synergistic function.Compared with existing unitary agent, parasite killing is imitated Fruit significantly improves, and the lasting period is long, to crop safety, is worth popularization and application in agricultural production.
