Abstract

The invention relates to a synergistic insecticidal composition containing spinosad and flonicamid, and an application thereof. The synergistic insecticidal composition employs spinosad and flonicamid as main effective components, wherein a weight ratio of spinosad to flonicamid is 0.1-80 : 0.1-50. The insecticidal composition can produce a relatively high synergistic interaction effect, overcomes or delays insect resistance, enlarges prevention spectrum, has fast insecticidal speed and reduces pesticide cost. The insecticidal composition can be used for preventing lepidoptera pests and has an effect obviously higher than that of a single dosage.

Description

Contain Synergistic insecticidal compositions of pleocidin and flonicamid and uses thereof
Technical field
The invention belongs to pesticide field, be specifically related to a kind of Synergistic insecticidal compositions that contains pleocidin and flonicamid and uses thereof.
Background technology
Pleocidin (spinosad) compounds is first new type natural insecticide that is developed by Dow AgroSciences, derive from the secondary metabolite that soil actinomycetes thorniness saccharopolyspora strain (saccharopolyspora spinosa) obtains through aerobic fermentation in culture medium, its active ingredient is to encircle greatly pleocidin spinosyn A and spinosyn D.
Pleocidin can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some takes food the insect of blade in a large number in coleoptera and the orthoptera.
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.
At present, the resistance of lepidoptera pest 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 lepidoptera pest.The inventor finds after deliberation, and agriculture chemical compounding can obviously improve drug effect, and can delay the generation of pest resistance.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains pleocidin and flonicamid, this Pesticidal combination production cost is low, have quick-acting and the long-acting pesticidal effect.
The present invention also provides this Insecticidal combinations to prevent and treat application in the insecticidal materials of resistance lepidoptera pest in preparation.
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 pleocidin and flonicamid insecticidal properties, and pleocidin and flonicamid is composite according to certain ratio, obtains Pesticidal combination of the present invention.
The objective of the invention is to implement in the following manner:
A kind of Synergistic insecticidal compositions that contains pleocidin and flonicamid, it is take pleocidin and flonicamid as main active ingredient, and wherein, the weight ratio of pleocidin and flonicamid is 0.1~80: 0.1~50.The weight ratio of preferred pleocidin and flonicamid is 0.5~60: 0.5~40.The weight ratio of pleocidin and flonicamid more preferably 1~30: 1~30 most preferably is 1~10: 1~10.
In the present composition, the two weight percentage that accounts for composition of pleocidin and flonicamid is 1~85%, and the preferred weight percentage composition is 6~50%." % " of the present invention is mass percent.
This Pesticidal combination is take pleocidin and flonicamid as main active ingredient (active component) with any one formulation that allows on insecticides adjuvant and the excipients preparation agricultural chemicals, preferred missible oil, aqueous emulsion, microemulsion or suspending agent.Described 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 solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent, excipient can be alone or and with or also add other auxiliary material.
Above-mentioned Pesticidal combination is prevented and treated application in the insecticidal materials of resistance lepidoptera pest in preparation, especially uses to have remarkable result in the insecticidal materials of the insects such as preparation control thrips, diamond-back moth and beet armyworm.
Beneficial effect of the present invention:
The invention provides the Pesticidal combination of a kind of pleocidin and flonicamid, it compared with prior art can produce higher synergistic function, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, reduced drug cost, its successful is higher than its single dose to be used.
