Abstract

The invention discloses a synergistic insecticidal composition containing flonicamid and silafluofen and application thereof. The synergistic insecticidal composition comprises main effective components of flonicamid and silafluofen in a weight ratio of 0.1-80:0.1-55. The composition provided by the invention can be used for the control of Hemiptera insects and produce high synergism, overcomes and delays the insect resistance, expands spectrum of control, and has fast insecticidal speed, reduced drug usage cost, and especially has control effect on aphid and whitefly significantly higher than that of a single agent.

Description

Synergistic insecticidal compositions of a kind of fluorine-containing pyridine insect amide and silafluofene and uses thereof
Technical field
The invention belongs to pesticide field, relate to a kind of Pesticidal combination and uses thereof, especially a kind of Pesticidal combination take flonicamid and silafluofene as active component and uses thereof.
Background technology
Flonicamid (flonicamid, flunicotamid), chemical name: N-cyanogen methyl. (trifluoromethyl) vitamin PP.
Flonicamid belongs to the lower toxicity insecticide variety.This agent is effective to various suckings pest, and has good osmosis.It can be from root to stem, the infiltration of leaf section, but by leaf section to stem, root osmosis relatively a little less than.
This medicament causes effect by hindering the insect act of sucking.Insect stops to suck after taking in medicament very soon, and is last hungry and dead.
Insect according to electronics sucks behavior (EMIII) parsing, and this agent can make the lancet tissue of the sucking insects such as aphid can't insert plant tissue and cause effect.10% water dispersible granules, every 667m when the insects such as vegetable aphid such as control cucumber 2Use 10% water dispersible granules 30-50g that water is sprayed.When for fruit aphids such as control apples, add water 2500-5000 with 10% water dispersible granules and doubly spray.Use proof through test and land for growing field crops, flonicamid is to various aphids, plant hopper, aleyrodid, leafhopper, fruit bat, wireworm, thrips, ant class, leaf miner, and the first-class sucking pest of springtail has special efficacy, and pests with chewing mouthparts is also had good control efficiency.
Silafluofene (alphacypermethrin) chemical name: (4-ethoxybenzene) [4-fluoro-(3-phenoxy group benzene) propyl group] dimethylsilane, it is a kind of siliceous novel Organophosphorus insecticides thing, tool stomach toxicity and action of contace poison have the characteristics such as activity is high, low to mammal and toxicity in fish, stable chemical nature.Termite is shown good repellent action.Rat acute per os LD 50Greater than 5000 mg/kgs.
At present, the Semiptera insect, such as termite, aphid etc., resistance increases gradually, and the agricultural chemicals single dose descends gradually to the effect of control of insect, there is no effective preparation for the control of Semiptera insect.The inventor finds that after deliberation the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, not yet finds up to now the Pesticidal combination of relevant flonicamid and silafluofene.
Summary of the invention
The Synergistic insecticidal compositions that the purpose of this invention is to provide a kind of fluorine-containing pyridine insect amide and silafluofene, but this Pesticidal combination high-efficiency prevention and control resistance Semiptera insect, production cost is low, have quick-acting and the long-acting pesticidal effect.
The present invention also provides this Insecticidal combinations to prevent and treat application in the resistance Semiptera insect insecticidal materials in preparation.
For achieving the above object, the present invention takes full advantage of both mutual supplement with each other's advantages by the network analysis to flonicamid and silafluofene insecticidal properties, and flonicamid and silafluofene is composite according to certain ratio.
The objective of the invention is to implement in the following manner:
The Synergistic insecticidal compositions of a kind of fluorine-containing pyridine insect amide and silafluofene is characterized in that this Synergistic insecticidal compositions take flonicamid and pyridalyl as main active ingredient, and wherein, the weight ratio of flonicamid and silafluofene is 0.1~80: 0.1~55.The weight ratio of preferred flonicamid and silafluofene is 0.2~50: 0.5~50, and the weight ratio of further preferred flonicamid and silafluofene is 0.5~30: 1~40.
In the present composition, the two weight percentage that accounts for composition of flonicamid and silafluofene is 1~80%.Preferably the two weight percentage that accounts for composition is 3~50%." % " of the present invention is mass percent.
Pesticidal combination of the present invention take flonicamid and silafluofene as main active ingredient (active component) and insecticides adjuvant, excipient be mixed with any one formulation that allows on the agricultural chemicals.The preferred missible oil of described formulation, aqueous emulsion, microemulsion and suspending agent.Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, emulsifier 600 #, polyoxyethylene polyoxy third rare block compound (such as farming breast 33 #), the one or more combinations in the polyoxyethylene nonylphenol ether, excipient comprises cyclohexanone, solvent naphtha, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent, excipient can alone or also also can add other auxiliary material mixing use with reaching.
Above-mentioned Pesticidal combination is prevented and treated application in the insecticidal materials of resistance Semiptera insect in preparation, especially anti-eliminate aphis and aleyrodid on successful be higher than its single dose and use
Beneficial effect of the present invention:
The invention provides the Pesticidal combination of a kind of flonicamid and silafluofene, it compared with prior art can produce higher synergistic function, and overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has reduced drug cost.Compare with single dose, said composition antagonism Semiptera insect has notable synergistic such as aphid and aleyrodid etc., has obviously improved control efficiency.
