Description

The suspension emulsion of a kind of multiple killing teichomycin and cartap and application
Technical field
The invention belongs to the technical field that agricultural chemical insecticide is composite, be specially suspension emulsion and the application of a kind of multiple killing teichomycin and cartap.
Background technology
Multiple killing teichomycin
It is a kind of macrolides Nuisanceless high-efficient biological insecticides extracted in sugared many born of the same parents bacterium (Saccharopolysporaspinosa) zymotic fluid of thorn 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.'s (being now Dow Agrosciences LLC) finds that this bacterium can produce the very high compound of insecticidal activity, and practical product is the mixture of spinosyn A and spinosyn D, therefore is 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.Also do not know whether have cross tolerance with the insecticide of other types at present.These compounds can cause target plant-feed insect as dead rapidly in caterpillar, leaf miner, thrips and leaf-feeding beetle, although administrative department is strongly required to use when resistance does not occur, the moderate residual activity of this compound reduces the possibility of resistance and mass-sending life.When applying with 12-150g/hm, find no poisoning.
Fusing point (DEG C): Spinosyn A:84.0 ~ 99.5, Spinosyn D:161.5 ~ 170.
Solvability: water 235mg/L(PH=7); Can with arbitrary proportion and alcohols, aliphatic hydrocarbon, aromatic hydrocarbon, halogenated hydrocarbons, ester class, ethers and ketone miscible.
Have insect and tag fast and stomach poison function, have stronger osmosis to blade, can kill subepidermal insect, the longevity of residure is longer, has certain ovicidal action to some insects.Without systemic action.Be suitable for vegetables, fruit tree, gardening, crops use, insecticidal effect affects less by raining.Make insect generally produce very strong pesticide resistance to such medicament, preventive effect is not equal to before.
Cartap
Molecular formula: C 7h 15n 3o 2s 2hCl
Molecular mass: 273.81
S, S'-[2-(dimethylamino)-1,3-propane two base] thiocarbamate hydrochloride
Character description: white powder, fusing point 179-181 DEG C.Water-soluble, be slightly soluble in methyl alcohol, ethanol, be insoluble to the organic solvents such as acetone, ether, ethyl acetate, chloroform, benzene.The aqueous solution pH of 1% is 3-4.Normal temperature and stable under acidic conditions, unstable under alkali condition.
Cartap stomach poison function is strong, has simultaneously and tags and the effect such as certain food refusal, ovicidal.Knock down soon insect, the longevity of residure is long, desinsection wide spectrum.
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 the application thereof that have multiple killing teichomycin and cartap; said composition active ingredient is multiple killing teichomycin and cartap; wherein the weight ratio of multiple killing teichomycin and cartap is; multiple killing teichomycin: cartap=5:1-15:1; farthest alleviate the problem of current pest resistance to insecticide, thus decrease the consumption of agricultural chemicals, also alleviate the impact for environment; meet the trend of future society environmental protection, composition of the present invention receives best crop protection effect.
Technical scheme of the present invention is:
A suspension emulsion for multiple killing teichomycin and cartap, active ingredient is multiple killing teichomycin and cartap, and wherein the weight ratio of multiple killing teichomycin and cartap is, multiple killing teichomycin: cartap=5:1-15:1.
As preferably, the weight ratio of multiple killing teichomycin and cartap is, multiple killing teichomycin: cartap=8:1-12:1.
The suspension emulsion of multiple killing teichomycin of the present invention and cartap, it consists of following component by weight percentage:
Multiple killing teichomycin 10-70%,
Cartap 1-10%,
Methylate rapeseed oil 3-10%,
Lauryl sodium sulfate 1-3%,
Peaceful newborn 36# 5-10%,
Propane diols 1-5%,
Acrylate homopolymer sodium salt calcium lignosulfonate 1-2%,
Tributyl phosphate 1-4%,
Aluminium-magnesium silicate 3-5%,
Glutaraldehyde 0.5-1.5%,
Water surplus.
As preferably, the suspension emulsion of multiple killing teichomycin of the present invention and cartap, it consists of following component by weight percentage:
Multiple killing teichomycin 20-50%,
Cartap 2-6%,
Methylate rapeseed oil 3-10%,
Lauryl sodium sulfate 1-3%,
Peaceful newborn 36# 5-10%,
Propane diols 1-5%,
Acrylate homopolymer sodium salt calcium lignosulfonate 1-2%,
Tributyl phosphate 1-4%,
Aluminium-magnesium silicate 3-5%,
Glutaraldehyde 0.5-1.5%,
Water surplus.
Wherein, the total weight percentage of described active ingredient is 25-55%.
The suspension emulsion of multiple killing teichomycin of the present invention and cartap, for preventing and treating thorn apple rust mite, black peach aphid, apple aphid, is particularly useful for preventing and treating apple aphid.
Beneficial effect of the present invention is:
Said composition is compound suspend emulsion composition, compared with single product, there is the feature of binary composition, significantly enhance effect, delay the generation of pest resistance to insecticide, and expand effective active control spectrum, have 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 alleviate the problem of current pest resistance to insecticide, thus decrease the consumption of agricultural chemicals, also alleviate the impact for environment, meet the trend of future society environmental protection.The control efficiency of composition of the present invention is especially good to control apple aphid, mainly by the result of the synergistic function between each component.
Study the compound synergic of composition of the present invention, test adopts apple aphid to be used for test.
Toxicity index and the mixed co-toxicity coefficient (CTC value) of medicament is calculated according to the abundant method of Sun Yun.
Table 1 different ratio relation is to the toxicity test result of apple aphid
Process Co-toxicity coefficient
Multiple killing teichomycin 5: cartap 1 200.9
Multiple killing teichomycin 8: cartap 1 302.7
