Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of new and effective insect aerosol synergist.
Background technology
Insect aerosol synergist generally be take chemical synergists as main, and the most frequently used is Octacide 264 (MGK-264) and Butacide (S1).Octacide 264 is wherein to use the most general insect aerosol synergist, and it is better that it has effect, advantage with low cost, and Butacide (S1) cost is very high.Therefore now in the urgent need to seeking a kind of insect aerosol synergist of high efficiency, low cost, make up the blank in synergist market.Azone is that the outer optimal new and effective nontoxic infiltration of a kind of Now Domestic promotes synergist, there is strong short oozing property, emulsification compatibility and good infiltration adhesive force, can make various pesticide with high permeability with all kinds of mixed pesticides, can spread rapidly the cuticula of wetting animals and plants damage by disease and insect body surface, impel farm chemical ingredients effectively to enter in body until target, killing effect significantly improves, and can reduce and eliminate the pesticide resistance of damage by disease and insect, in equal drug effect situation, the active ingredient of pesticide with high permeability declines more than 50% than former agricultural chemicals, the production cost 30%-50% that can decline.Fatty alcohol-polyoxyethylene ether is widely used in daily use chemicals, has fabulous infiltration, moistens and emollescence multiplex emulsifier, bleeding agent and the wetting agent of making dyeing and printing products.More in the pesticide synergistics such as desinsection, sterilization and weeding, penetration enhancing activity research about azone and fatty alcohol-polyoxyethylene ether, and report seldom aspect insect aerosol synergist.The data-searching of carrying out according to applicant, does not retrieve azone and the fatty alcohol-polyoxyethylene ether application document aspect insect aerosol synergist.
Summary of the invention
In order to study azone and fatty alcohol-polyoxyethylene ether in the application in insect aerosol synergist field, the object of the invention is to, a kind of new and effective insect aerosol synergist is provided.
In order to realize above-mentioned task, the present invention takes following technical solution:
A kind of insect aerosol synergist, it is characterized in that, the form that makes this synergist is oil-based liquid preparation, by following raw materials by weight, formed: azone: 5%～25%, fatty alcohol-polyoxyethylene ether: 10%～30%, emulsifier: 10%～30%, solvent: 15%～75%, the percentage sum of raw material is 100%.
Above-mentioned insect aerosol synergist becomes potentiating pesticidal aerosol liquid filling with pesticide species formulated in combination, its preparation form is aerosol.Pesticide species is the cinerins agricultural chemicals such as dtetramethrin or rich_d_transallethrin or d-phenothrin or beta-cypermethrin.
In above-mentioned potentiating pesticidal aerosol, the percentage by weight formula of each composition is: insect aerosol synergist: 0.3%～0.8%, pesticide species: 0.2%～1.0%, stabilizing agent: 2%～5%, solvent: 93.2%～97.5%, the percentage by weight sum of each composition is 100%.
Aforementioned stable agent is BHT, and solvent is debrominate kerosene.
Through applicant's evidence, this insect aerosol synergist and pesticide species form synergetic pesticide composition has good synergistic effect to pesticide species, safe noresidue, environment friendly and pollution-free, synergy target is many, synergy mode is various, insect is difficult for developing immunity to drugs, smell can be used for well the features such as odorless formulation, can reduce the consumption of insect aerosol pesticide original medicine, reduce production costs, improve insecticidal effect.And wide material sources, efficient, low toxicity, environmental protection, can be widely used in insect aerosol product, has good Application and Development potentiality.
Embodiment
Below by test, implement that the present invention is described in further detail.
Applicant, in to the research process of insect aerosol synergist, through long-term research, finds that azone and fatty alcohol-polyoxyethylene ether have synergistic effect to the pesticide species in insect aerosol.
According to technique scheme, the form of this insect aerosol synergist is oil-based liquid preparation, consists of: azone: 5% ~ 25% following raw materials by weight, fatty alcohol-polyoxyethylene ether: 10% ~ 30%, emulsifier: 10% ~ 30%, solvent: 15% ~ 75%, the percentage sum of raw material is 100%.
