Description

A kind of Synergistic insecticidal compositions and application thereof that contains alpha-cypermethrin and flonicamid
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions and application thereof take alpha-cypermethrin and flonicamid as main active ingredient.
Background technology
Alpha-cypermethrin (alphacypermethrin), chemical name: (RS)-and cyano group (3-phenoxy phenyl) methyl (IRS) cis is trans-3-(2,2-dichloroethylene)-2, and 2-dimethyl cyclopropane carboxylic acid ester.
Alpha-cypermethrin can be used the control of the pest on crop such as cotton, vegetables, fruit tree, tea tree, soybean and beet.The control efficiency that the various pests such as the Lepidoptera on cotton and the fruit tree, Semiptera, diptera, orthoptera, coleoptera, thrips and Hymenoptera have all been had.Cotton bollworm, pink bollworm, cotten aphid, lychee stink-bug and citrus leaf-miner there is special efficacy.
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.
The homoptera pests such as rice fulgorid, Bemisia tabaci, 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, there is no effective preparation for the control of homoptera pest.The inventor finds after deliberation, and the composite of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, finds not yet that up to now the complex insecticidal composition of relevant alpha-cypermethrin and flonicamid is used for preventing and treating the resistance homoptera pest.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains alpha-cypermethrin and flonicamid, this Pesticidal combination production cost is low, have quick-acting and the long-acting pesticidal effect.
The present invention also provides the application on this Insecticidal combinations prevents and treats the resistance homoptera pest in preparation the insecticidal materials.
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 alpha-cypermethrin and flonicamid insecticidal properties.
The objective of the invention is to implement by the following technical programs:
A kind of Synergistic insecticidal compositions that contains alpha-cypermethrin and flonicamid, this Synergistic insecticidal compositions is take alpha-cypermethrin and flonicamid as main active ingredient, wherein, the weight ratio of alpha-cypermethrin and flonicamid is 0.1~70: 0.1~80.The weight ratio of alpha-cypermethrin and flonicamid preferred 0.5~50 in this Synergistic insecticidal compositions: 0.5~60, more preferably 1~40: 10~50.
In the above-mentioned Synergistic insecticidal compositions, the two accounts for the weight percentage 1~80% of composition alpha-cypermethrin and flonicamid, and the best is 4~60%.Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
This Pesticidal combination is take alpha-cypermethrin and flonicamid as main active ingredient (active component) and insecticides adjuvant, excipient are mixed with take alpha-cypermethrin and flonicamid as main active ingredient and insecticides adjuvant, excipients are mixed with any one formulation that allows on the agricultural chemicals.The preferred missible oil of described formulation, aqueous emulsion, microemulsion or suspending agent.Above-mentioned 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 with reaching.
The various pests that Pesticidal combination antagonism homoptera pest, particularly aphid of the present invention, Bemisia tabaci, plant hopper etc. easily produce resistance has good preventive effect, and effect is significantly higher than the application of alpha-cypermethrin and flonicamid single dose.
Therefore, the present invention's Synergistic insecticidal compositions of containing alpha-cypermethrin and flonicamid is used at the insecticidal materials of preventing and treating the resistance homoptera pest.Particularly in the insecticidal materials of preparation control water rice hopper, Bemisia tabaci and aphid, use.
" % " of the present invention is mass percent.
Pesticidal combination of the present invention compared with prior art, produce following beneficial effect: (1) is compared with single dose, present composition antagonism homoptera pest has obviously improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with flonicamid or alpha-cypermethrin single dose, produce and the use cost reduction; (6) suppress homoptera pest to the resistance enhancing of agricultural chemicals.
