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
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof that flonicamid and pyridalyl be main active ingredient of take.
Background technology
Flonicamid (flonicamid, flunicotamid), chemical name: N-cyanogen methyl. (trifluoromethyl) vitamin PP.Flonicamid belongs to 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 portion, but by leaf portion to stem, root osmosis relatively a little less than.This medicament causes effect by hindering insect act of sucking.Insect stops sucking after taking in medicament very soon, 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 cannot 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 to spray water.When preventing and treating the fruit aphids such as apple, with 10% water dispersible granules, add water 2500-5000 and doubly spray.Through test and land for growing field crops, use proof, 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 to good control efficiency.But at present, the homoptera pests such as plant hopper and aphid are under the condition of long-term prescription, resistance increases gradually, uses separately flonicamid can not effectively prevent and treat this class pest.
Pyridalyl (pyridalyl), chemical name 2, the chloro-4-of 6-bis-(3,3-, bis-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 agricultural production is had to very high insecticidal activity.In addition, pyridalyl also demonstrates good insecticidal activity to thrips and dipterous insect, contrary with its high activity, and pyridalyl is very low to various useful arthropodan toxicity.
Summary of the invention
The object of this invention is to provide a kind of Synergistic insecticidal compositions containing flonicamid and pyridalyl.
Another object of the present invention is to provide above-mentioned Synergistic insecticidal compositions and prevents and treats the application in resistance Semiptera insect insecticidal materials in preparation.
For achieving the above object, the present invention is composite by different two kinds of insecticidal materials flonicamids and the pyridalyl of controlling object, obtains the new and effective multifunctional insecticide composition of a class.The various pests that this Pesticidal combination easily produces resistance to rice fulgorid, aphid, diamond-back moth has good preventive effect; And suppress insect the pesticide resistance of unitary agent (flonicamid or pyridalyl) is produced.
The present invention adopts following technical scheme:
Containing a Synergistic insecticidal compositions for flonicamid and pyridalyl, it is characterized in that it is main active ingredient that this Synergistic insecticidal compositions be take flonicamid and pyridalyl, wherein, the weight ratio of flonicamid and pyridalyl is 0.1～80: 0.2～70.
In this Synergistic insecticidal compositions, the weight ratio of flonicamid and pyridalyl preferably 0.5～60: 2～50, and 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.
It is main active ingredient (active component) that above-mentioned Insecticidal combinations be take flonicamid and pyridalyl, and insecticides adjuvant, excipients are mixed with any one formulation allowing on 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, if calcium dodecyl benzene sulfonate, emulsifier 600 #, the rare block compound of polyoxyethylene polyoxy third are (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., excipient can adopt cyclohexanone, solvent naphtha, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Auxiliary agent, excipient can alone or mixing use, also can add other auxiliary material allowing on pesticidal preparations.
Above-mentioned Pesticidal combination can be prevented and treated the 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 Semiptera insect, is all 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 providing of the present invention and pyridalyl Pesticidal combination, can produce higher synergistic function, desinsection speed is fast, overcome and delayed pest resistance to insecticide, expanding prevention spectrum, has reduced drug cost simultaneously, and its successful is used higher than its single dose.
