Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic insecticidal compositions that contains rotenone and Affirm (Merck Co.).
Background technology
Rotenone is the efficient insecticide active substance of generally acknowledging in the world, and it is to environment, people and animals, pest natural enemy and other beneficial organism safety, and insect is not easy to develop immunity to drugs; Affirm (Merck Co.) is a kind of new and effective semisynthetic antibiotics insecticide that begins to synthesize from fermented product AVM B1; It has super-high-efficient, low toxicity (preparation is closely nontoxic), low-residual; The nuisanceless characteristics that wait biopesticide; With AVM at first insecticidal activity improved 3 one magnitude, active high to the larva of lepidopterous insects and other many insects, the double again action of contace poison of existing stomach poison function; Under low-down dosage (active ingredient 0.084～2 gram/hectare), have good effect, and in the process of pest control, beneficial insect is not injured.Rotenone and Affirm (Merck Co.) all belong to environment amenable insecticide active substance, and the two is mixed and helps the integrated control to insect, has enlarged insecticidal spectrum, has reduced the toxicity to people and animals.
Development along with agricultural science; Especially country strengthened the attention to agricultural development in nearly 2 years; Importance at control agricultural disease, worm, grass is particularly outstanding; Develop multiple rotenone, Affirm (Merck Co.) insecticide variety in succession, but mostly formulation is missible oil or single agent composition, this situation causes the use of agricultural chemicals when improving crop yield, also to accelerate the rapid raising of pest resistance to insecticide.
The modern formulations of pesticide promptly are the formulations of pesticide of matrix with water, promptly with big old formulations of missible oil of water baseization pesticidal preparations replace organic solvent consumption such as suspending agent, microemulsion, aqueous emulsions towards water baseization, ultramicronising, no efflorescence and the development of sustained release aspect.Wherein microemulsion, aqueous emulsion are the novel pesticide formulations that a kind of organic solvent can lack usefulness, good drug efficacy, environmentally-friendly water-basedization, also are a kind of good liquid dosage forms that replaces emulsifiable concentrates for agricultural chemicals.After the applicant reasonably is mixed to rotenone and Affirm (Merck Co.) through great deal of experimental, has reached and can overcome pest resistance to insecticide, the expanding prevention spectrum reduces the purpose of consumption.
Being mixed and using of rotenone and Affirm (Merck Co.) still do not have report at present.
Summary of the invention
The purpose of this invention is to provide a kind of Synergistic insecticidal compositions that contains rotenone and Affirm (Merck Co.), said composition has active height, good stability, advantage that control efficiency is good.
The present invention is that environment amenable insecticide active substance rotenone and Affirm (Merck Co.) is composite, is mixed with the pesticidal preparations of water baseization.
The present invention is achieved through following technical scheme: a kind of Synergistic insecticidal compositions each component that contains rotenone and Affirm (Merck Co.) is following by weight percentage: rotenone 0.5～5%; Affirm (Merck Co.) 1～10%; Solvent 5～40%, anion-nonionic phenotype surfactant 5～20%, assistant for emulsifying agent 0.05～5%; Stabilizing agent 0.5～3%, all the other waters complement to 100%.
Described solvent is one or more the combination in methyl alcohol, ethanol, ether, acetone, cyclohexanone, ethyl acetate, dimethyl formamide, N-Methyl pyrrolidone, diethyl phthalate, dibutyl phthalate, the alkane.
In described anion-nonionic phenotype surfactant, mark meter by weight, non-ionic surface active agent is 40～80%, and anion surfactant is 1～10%, and surplus is a hydrophilic organic solvent.
Described non-ionic surface active agent is made up of two or more non-ionic surface active agents.
Described non-ionic surface active agent is benzylphenol APEO, alkaryl phenol polyethenoxy ether phosphate, AEO, APES, castor oil polyoxyethylene ether, dehydrating sorbitol monooleate, styryl phenyl APEO or polyol fatty acid ester.
Described anion surfactant is one or more the combination in alkylbenzenesulfonate, ether alcohol sulfate, triphen ethyl-phenol polyoxyethylene phosphate or the sulphate.
Described hydrophilic organic solvent is one or more the combination in methyl alcohol, ethanol, n-butanol, the ethyl acetate.
Described assistant for emulsifying agent is one or more the combination in propyl alcohol, hexanol, octanol, isobutanol, ethylene glycol, glycerine, cyclohexanol, methyl diethylene glycol (DEG), ethyl diethylene glycol (DEG), castor oil, lauryl sodium sulfate, potassium chloride, the sodium sulphate.
Described stabilizing agent is antioxidant 264, epoxidized soybean oil, epoxy linseed oil, epoxy fat, pentaerythrite, xylitol, pyrogallic acid.
Described a kind of Synergistic insecticidal compositions that contains rotenone and Affirm (Merck Co.) can be mixed with aqueous emulsion or microemulsion.
Preparation method of the present invention: at first all be dissolved in rotenone and Affirm (Merck Co.) in the solvent; Then emulsifier is slowly added in the entry, stir when adding emulsifier, form emulsifier aqueous solution; Add assistant for emulsifying agent and stabilizing agent again, stir; Directly join rotenone and the Affirm (Merck Co.) of dissolving at last and mix stirring in the emulsifier aqueous solution or sheared 0.5～1.0 hour, obtain microemulsion or aqueous emulsion.Synergistic insecticidal compositions of the present invention has following beneficial effect.
1, the present invention substitutes most organic solvent with water, reduces environmental pollution, helps ecological environmental protection; Reduce production costs, save a large amount of petrochemical industry resources, and the present invention adopts and not contain the phenyl ring class and to the solvent of environment or human body low toxicity; Significantly reduce organic solvent to the pollution of human body and environment and residual; Produce pollution, explosive and poisoning problem in avoiding producing, pesticide processing is hanged down poison, ensure human and mammiferous safety and health.
2, rotenone provided by the invention, Affirm (Merck Co.) and anion-nonionic phenotype surfactant and the Synergistic insecticidal compositions prepared; Said composition spray droplet in use is little, to crop and polypide have better wetting, sprawl, adhere to and permeability, it is many to absorb soup; Improve drug effect; Said composition improves crop pests is active, compares with the rotenone or the Affirm (Merck Co.) microemulsion of prior art, and stability is strong, safety is good.Synergistic insecticidal compositions of the present invention is being diluted under the identical situation of application concentration; The control efficiency of Synergistic insecticidal compositions of the present invention is apparently higher than rotenone of the prior art or the single preparation of Affirm (Merck Co.); Have efficient, low toxicity, pollution-free simultaneously; Environmentally friendly, person poultry safety, the characteristics that usage amount reduces, be difficult for developing immunity to drugs to insect.
