Abstract
The invention discloses a compound insecticidal composition containing flonicamid and chlorfenaypr, and an application thereof. The synergistic insecticidal composition employs flonicamid and chlorfenaypr as main effective components, wherein a weight ratio of flonicamid to chlorfenaypr is 0.1-80 : 0.5-80. The insecticidal composition can produce a relatively high synergistic interaction effect, overcomes or delays pest resistance, has fast insecticidal speed and long efficacy duration, reduces pesticide cost and has a prevention effect obviously higher than that of a single dosage. The insecticidal composition can be used for preventing homoptera pests generated on crops, and is particularly suitable for preventing rice hopper and aphid, with an effect obviously higher than that of the single dosage.
Description
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 capillary 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.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.
Capillary (chlorfenapyr); Chemical name is: 4-bromo-2-(4-chlorphenyl)-1-(ethoxyl methyl)-5-(trifluoromethyl) pyrroles-3-nitrile, and structural formula is:
This medicine is the new pyrrole compounds, acts on the mitochondria of insect bodies inner cell, works by the mixed-functional oxidase in the insect bodies, mainly suppresses adenosine diphosphate (ADP) to the conversion of adenosine triphosphate (ATP).And adenosine triphosphate storage cell is kept the necessary energy of its vital functions.This medical instrument has stomach toxicity and action of contace poison.Permeability is strong on the blade face, and certain systemic action is arranged, and has the advantages that insecticidal spectrum is wide, preventive effect is high, holding effect is long, safe.Can control resistant insect.
Capillary has insect tags and fumigation action, and the power of knocking down is strong, and holding effect is short.Can prevent and treat the various vegetables insects such as diamond-back moth, cabbage caterpillar, beet armyworm, prodenia litura, Oeobia undalis, vegetable aphid, liriomyza bryoniae, thrips.Poisonous to fish.
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 capillary.
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 capillary, this Pesticidal combination is take flonicamid and capillary as main active ingredient, and wherein, the weight ratio of flonicamid and capillary 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 capillary is 3～80%.Be preferably 5～55%, most preferably 10～40%.
Pesticidal combination of the present invention take flonicamid and capillary 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 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 comprises isopropyl alcohol, vegetable oil, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent and excipient all can use one or more.
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 capillary are arbitrary).Therefore, above-mentioned Pesticidal combination is prevented and treated the application on the insecticidal materials of resistance homoptera pest in preparation, and especially the effect on the insecticidal materials of preparation control aleyrodid, rice fulgorid or aphid is remarkable.
" % " of the present invention is mass percent.
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 capillary 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.
