The insecticidal composition comprises main effective components of flonicamid and fenvalerate in a weight ratio of 0.1-80: 0.5-80. The insecticidal composition can produce high synergetic effect, overcomes and delays insect resistance, and has high insecticidal speed, long duration, reduced use cost, and control effect obviously better than that of a single agent. The composition provided by the invention can control Homoptera pests in crops, especially rice planthopper and aphid, and has effect obvious better than that of a single agent.

Description

Compound pesticide compositions of a kind of fluorine-containing pyridine insect amide and sumicidin and uses thereof
Technical field
The invention belongs to pesticide field, be specifically related to compound pesticide compositions of a kind of fluorine-containing pyridine insect amide and sumicidin 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.
Sumicidin (fenvalerate) has another name called: Belmark, kill the chrysanthemum ester, Belmark, isoamyl Cyano chrysanthemate, Belmark.Chemical name is: (R, S)-a-cyano group-3-phenoxy benzyl (R, S)-2-(4-chlorphenyl)-3 Methylbutanoic acid ester, and structural formula is:
Sumicidin is the pyrethroid insecticides of high-efficiency broad spectrum, and insecticidal spectrum is wide, to the natural enemy non-selectivity, to tag with stomach poison function as main, without interior suction conduction and fumigation action.Effective to lepidopterous larvae, the insects such as Homoptera, orthoptera, Semiptera also there is better effects, invalid to the mite class.And to the volume increase of crop with promote that precocity has certain effect.To the people, animal moderate toxicity.
But rice fulgorid and aphid are under the condition of present long-term prescription, and resistance increases gradually, and the agricultural chemicals single dose descends gradually to the effect of control of 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 sumicidin.
Summary of the invention
The compound pesticide compositions that the purpose of this invention is to provide a kind of fluorine-containing pyridine insect amide and sumicidin, this Pesticidal combination are the multifunctional insecticide compositions of control homoptera pest.
Another object of the present invention provides this Pesticidal combination and prevents and treats application on the insecticidal materials of resistance homoptera pest in preparation, particularly the application on the insecticidal materials of preparation control plant hopper, aleyrodid or aphid.
The objective of the invention is to be achieved through the following technical solutions:
The compound pesticide compositions of a kind of fluorine-containing pyridine insect amide and sumicidin, this Pesticidal combination is take flonicamid and sumicidin as main active ingredient, and wherein, the weight ratio of flonicamid and sumicidin is 0.1~80: 0.5~80.Be preferably 0.5~50: 2~50, more preferably 0.5~10: 4~30.Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
In compound pesticide compositions of the present invention, the two weight percentage in this compound pesticide compositions of flonicamid and sumicidin is 3~80%.Be preferably 5~55%, most preferably 10~40%." % " of the present invention is mass percent.
Pesticidal combination of the present invention take flonicamid and sumicidin as main active ingredient and insecticides adjuvant and excipient be mixed with any one formulation that allows on the agricultural chemicals, the preferred emulsion of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion and water dispersion granule.
Auxiliary agent can adopt calcium dodecyl benzene sulfonate, emulsifier 600 #, polyoxyethylene polyoxy third rare block compound (such as the newborn 33# of farming), polyoxyethylene nonylphenol ether etc., and excipient comprises isopropyl alcohol, vegetable oil, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can alone or and usefulness.
Pesticidal combination of the present invention has good preventive effect to the multiple homoptera pest that rice fulgorid and aphid etc. produce resistance easily; And suppress insect to the pesticide resistance generation of unitary agent (flonicamid or sumicidin are arbitrary).
Above-mentioned Pesticidal combination is prevented and treated the application on the insecticidal materials of resistance homoptera pest in preparation, especially the effect on the insecticidal materials of preparation control aleyrodid, rice fulgorid or aphid is remarkable.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism homoptera pest such as rice fulgorid, aphid etc. have obvious synergistic function, overcome and have delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has obviously improved control efficiency; (2) reduce control recruitment, drug cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the sumicidin single dose with flonicamid, produce and the use cost reduction; (6) suppress homoptera pest to the resistance enhancing of agricultural chemicals, its successful is higher than its single dose to be used.
