Abstract

The invention discloses a synergistic insecticidal composition containing flonicamid and pyridalyl and application thereof. The synergistic insecticidal composition comprises main effective components of flonicamid and pyridalyl in a weight ratio of 0.1-80:0.2-70. The insecticidal composition can produce high synergetic effect, overcomes and delays the insect resistance, and has high insecticidal speed, long duration and reduced use cost. The composition provided by the invention can control hemipteran pests in crops, especially rice planthopper, whiteflies and aphids, and has effect obviously higher than that of a single agent.

Description

Synergistic insecticidal compositions and the application thereof of a kind of fluorine-containing pyridine insect amide and pyridalyl
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof take flonicamid and pyridalyl as main active ingredient.
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.But at present, the homoptera pests such as plant hopper and aphid are under the condition of long-term prescription, and resistance increases gradually, uses separately flonicamid can not effectively prevent and treat this class pest.
Pyridalyl (pyridalyl), chemical name 2,6-two chloro-4-(3,3-, two chloroallyloxyaminos) phenyl 3-[5-(trifluoromethyl-2 hydroxy pyrimidine) propyl group] ether.Structural formula is as follows:
Pyridalyl has simultaneously tags and stomach poison function, and the larva of lepidoptera pest main in the agricultural production is had very high insecticidal activity.In addition, pyridalyl also demonstrates good insecticidal activity to thrips and dipterous insect, and is opposite with its high activity, and pyridalyl is very low to various useful arthropodan toxicity.
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 pyridalyl.
Another object of the present invention provides above-mentioned Synergistic insecticidal compositions and prevents and treats application in the resistance Semiptera insect insecticidal materials in preparation.
For achieving the above object, two kinds of insecticidal materials flonicamids and pyridalyl that the present invention is different with controlling object are composite, obtain the new and effective multifunctional insecticide composition of a class.This Pesticidal combination has good preventive effect to the various pests that rice fulgorid, aphid, diamond-back moth easily produce resistance; And suppress insect to the pesticide resistance generation of unitary agent (flonicamid or pyridalyl).
The present invention adopts following technical scheme:
The Synergistic insecticidal compositions of a kind of fluorine-containing pyridine insect amide and pyridalyl is characterized in that this Synergistic insecticidal compositions take flonicamid and pyridalyl as main active ingredient, and wherein, the weight ratio of flonicamid and pyridalyl is 0.1~80: 0.2~70.
The weight ratio of flonicamid and pyridalyl preferred 0.5~60 in this Synergistic insecticidal compositions: 2~50, more preferably 1~30: 4~20.
In the present composition, the two percentage by weight that accounts for composition of flonicamid and pyridalyl is 3~80%.Be preferably 5~50%, most preferably 5~20%." % " of the present invention is mass percent.
Above-mentioned Insecticidal combinations is take flonicamid and pyridalyl as main active ingredient (active component), and insecticides adjuvant, excipients are mixed with any one formulation that allows on the agricultural chemicals.Be preferably missible oil, suspending agent, aqueous emulsion, wetting powder, microemulsion and water dispersion granule.
Described auxiliary agent specifically can adopt usual auxiliaries, such as calcium dodecyl benzene sulfonate, emulsifier 600 #, polyoxyethylene polyoxy third rare block compound (such as farming breast 33 #), polyoxyethylene nonylphenol ether etc., excipient can adopt cyclohexanone, solvent naphtha, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Auxiliary agent, excipient can alone or mixing and usefulness, also can add other auxiliary material that allows on the pesticidal preparations.
Above-mentioned Pesticidal combination can be prevented and treated application in the insecticidal materials of resistance Semiptera insect in preparation, and the control efficiency of the present composition is used apparently higher than its single dose, and described Semiptera insect refers in particular to rice fulgorid, aphid, aleyrodid.
Indoor bioassay and field control effectiveness test show that compound insecticidal medicine of the present invention has significant synergistic insecticidal action to the Semiptera insect, all is significantly higher than the effect of corresponding single dose agricultural chemicals especially to the insecticidal effect of water rice hopper, aphid, aleyrodid.
Beneficial effect of the present invention: the flonicamid that provides of the present invention and pyridalyl Pesticidal combination, can produce higher synergistic function, desinsection speed is fast, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum has reduced drug cost simultaneously, and its successful is higher than its single dose to be used.
