Abstract

The invention belongs to the technical field of compounding pesticides, and specifically relates to a suspoemulsion containing spinosad and tebufenpyrad and an application of the suspoemulsion. The effective components of the suspoemulsions are spinosad and tebufenpyrad in a weight ratio of 5:1-15:1. The suspoemulsion containing spinosad and tebufenpyrad relieves the problem of existing pest resistance to insecticide to the maximum extent, so that the use level of pesticides is reduced, and the influence on the environment is further relieved, thereby satisfying the trend of environmental protection of the future society. The composition provided by the invention has the optimal crop protective effect.

Description

The suspension emulsion of a kind of multiple killing teichomycin and tebufenpyrad and application
Technical field
The invention belongs to the composite technical field of agricultural chemical insecticide, be specially suspension emulsion and the application of a kind of multiple killing teichomycin and tebufenpyrad.
Background technology
Multiple killing teichomycin
It is a kind of macrolides Nuisanceless high-efficient biological insecticides that extract in thorn sugared many born of the same parents bacterium (Saccharopolyspora spinosa) zymotic fluid that multiple killing teichomycin has another name called pleocidin (Spinosad).Produce parent strain soil actinomycetes thorniness saccharopolyspora strain (the Saccharopolyspora spinosa Metrz & Yao) initial separation of pleocidin from one of Caribbean discarded wine brewing field.The researcher of The Dow Agrosciences, LLC. (Xian Wei Dow Agrosciences LLC) finds that this bacterium can produce the compound that insecticidal activity is very high, and practical product is the mixture of spinosyn A and spinosyn D, therefore be called spinosad.The mode of action of multiple killing teichomycin is novel, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Multiple killing teichomycin also can affect GABA acceptor, but mechanism of action is unclear.At present also do not know whether have cross tolerance with the insecticide of other types.These compounds can cause that target plant-feed insect is as dead rapidly in caterpillar, leaf miner, thrips and leaf-feeding beetle, although administrative department's strong request is not used when resistance occurs, the moderate residual activity of this compound has reduced resistance and the raw possibility of mass-sending.When applying with 12-150g/hm, find no poisoning.
Fusing point (℃): Spinosyn A:84.0~99.5, Spinosyn D:161.5~170.
Solvability: water 235mg/L(PH=7); Can be miscible with arbitrary proportion and alcohols, aliphatic hydrocarbon, aromatic hydrocarbon, halogenated hydrocarbons, ester class, ethers and ketone.
Insect is had and tagged fast and stomach poison function, blade is had to stronger osmosis, can kill subepidermal insect, the longevity of residure is longer, and some insects are had to certain ovicidal action.Without systemic action.Be suitable for using on vegetables, fruit tree, gardening, crops, insecticidal effect be subject to rain affect less.Make insect generally to such medicament, produce very strong pesticide resistance, preventive effect is not equal to before.
Tebufenpyrad
English name: Tebufenpyrad
Molecular formula: C18H24CLN3O
CA registration number: 119168-77-3
Chemical name: N-(4-tertiary butyl benzyl) the chloro-3-ethyl-1-of-4-methylpyrazole-5-base formamide
Fusing point (℃): 61~62
Vapour pressure: 0.010787mPa (40 ℃)
Purposes:
This product belongs to amide-type miticide.Various mite classes and Semiptera, homoptera pest are had to tall and erect effect, and all have immediate effect with efficient the dawn each vegetative period to mite class, the lasting period is long.
But its action effect is also very single, after large-scale application, resistance risk is also very high.
Summary of the invention
The object of the present invention is to provide a kind of suspension emulsion and application thereof that has multiple killing teichomycin and tebufenpyrad; said composition active ingredient is multiple killing teichomycin and tebufenpyrad; wherein the weight ratio of multiple killing teichomycin and tebufenpyrad is; multiple killing teichomycin: tebufenpyrad=5:1-15:1; farthest alleviate the problem of current pest resistance to insecticide, thereby reduced the consumption of agricultural chemicals, also alleviated the impact for environment; the trend that meets future society environmental protection, composition of the present invention is received best crop protection effect.
Technical scheme of the present invention is:
A suspension emulsion for multiple killing teichomycin and tebufenpyrad, active ingredient is multiple killing teichomycin and tebufenpyrad, wherein the weight ratio of multiple killing teichomycin and tebufenpyrad is, multiple killing teichomycin: tebufenpyrad=5:1-15:1.
As preferably, the weight ratio of multiple killing teichomycin and tebufenpyrad is, multiple killing teichomycin: tebufenpyrad=8:1-12:1.
The suspension emulsion of multiple killing teichomycin of the present invention and tebufenpyrad, it consists of following component by weight percentage:
Multiple killing teichomycin 10-70%,
Tebufenpyrad 1-10%,
150# solvent naphtha 3-10%,
Lauryl sodium sulfate 1-3%,
Agriculture breast 400 #5-10%,
Propane diols 1-5%,
Maleic acid disodium salt 1-2%,
Tributyl phosphate 1-4%,
Gelatin 3-5%,
Kathon CG 0.5-1.5%,
Water surplus.
As preferably, the suspension emulsion of multiple killing teichomycin of the present invention and tebufenpyrad, it consists of following component by weight percentage:
Multiple killing teichomycin 20-50%,
Tebufenpyrad 2-6%,
150# solvent naphtha 3-10%,
Lauryl sodium sulfate 1-3%,
Agriculture breast 400 #5-10%,

Wherein, the total weight percentage of described active ingredient is 25-55%.
The suspension emulsion of multiple killing teichomycin of the present invention and tebufenpyrad, for preventing and treating citrus red mite, Tetranychus cinnabarinus, panonychus ulmi, is particularly useful for preventing and treating panonychus ulmi.
Beneficial effect of the present invention is:
Said composition is compound suspend emulsion composition, compare with single product, the feature with binary composition, strengthened significantly effect, delay the generation of pest resistance to insecticide, and expanded effective active control spectrum, and thering is speed fast, the lasting period is long, consumption is low, eco-friendly feature, the more important thing is, this compounded combination has effectively resisted the problem that pest resistance produces, farthest alleviated the problem of current pest resistance to insecticide, thereby reduced the consumption of agricultural chemicals, also alleviated the impact for environment, met the trend of future society environmental protection.The control efficiency of composition of the present invention is especially good to control panonychus ulmi, is mainly by the result of the synergistic function between each component.
To the compound synergic research of composition of the present invention, test adopts panonychus ulmi for test.
According to the abundant method of Sun Yun, calculate the toxicity index of medicament and mixed co-toxicity coefficient (CTC value).
The toxicity test result of the different proportion relations of table 1 to panonychus ulmi
Process Co-toxicity coefficient
Multiple killing teichomycin 5: tebufenpyrad 1 147.9
