Description

Avermectin electrostatic oil agent and preparation method thereof
Technical field
The present invention relates to technical field of pesticide preparations, and in particular to avermectin electrostatic oil agent and preparation method thereof.
Background technique
Avermectin (Avermectins) belongs to efficient, wide spectrum, non-harmful biological source insecticide, mainly by B1aAnd B1b It forms, wherein B1a80% or more is accounted for, is the hexa-atomic big ring of one kind ten developed first by Japanese North university and United States Merck company Lactone compound has stomach toxicity and action of contace poison to mite class and insect, and has faint fumigation action, and no systemic action is right Blade has very strong osmosis, can kill subepidermal pest, and the lasting period is long.The insecticidal mechanism of avermectin is interference insect Nervous physiology activity, act on the γ-aminobutyric acid A receptor (GABAA) of insect, stimulation release γ-aminobutyric acid, interference The information transmitting of nerve endings in insect bodies leads to insect paralysis, food refusal, dead so that the non-tip of block nerves and muscle contact It dies.Avermectin can be used for preventing and treating various mite class, pear sucker, cabbage caterpillar, diamondback moth, golden line leaf moth, beet armyworm, leaf miner, Various pests or the harmful mites such as Liriomyza, Americal rice leaf miner and vegetables trialeurodes vaporariorum, especially have special efficacy to root-knot nematode.
Electrostatic oil agent is one kind of pesticidal preparations dosage form, it is low by selective volatilization, flash-point is high, it is high to raw medicine dissolubility, Organic solvent lower to chemical injury of crops, that viscosity is low is prepared, without adding water when electrostatic oil agent is administered, generally without addition Other organic solvents, but directly applied with electrostatic sprayer.Electrostatic Spraying technique is to apply high-pressure electrostatic in spray head and be sprayed Establish an electrostatic field between target, and liquid pesticide flows through after spray head is atomized under electrostatic field, passes through different charging sides Method is filled with charge, forms group's charged droplets, then under the synergy of electrostatic field force and other external force, droplet is oriented Each position of target is moved and is adsorbed on, it is good to reach that deposition efficiency is high, float of mist droplet scatters and disappears less, improves the ecological environment etc. Performance.
In general, compared to the traditional formulations of pesticide and application method, electrostatic oil agent is had the advantage that
1, electrostatic spray, which has, outflanks effect, point effect, penetration effect, covers uniformly to Target crops, deposition is high. Electrostatic spray makes the droplet of each ejection have same sex electrostatic charge, it is easier to be captured by target, and droplet is in spatial movement It is mutually exclusive, it does not agglomerate, the induction of Charged Droplet makes the external of crop generate the charges of different polarity, under the action of electric field force, Droplet quick adsorption improves deposition of the pesticide on Target crops to the front and back sides of crop, improves the equal of pesticide deposition Even property.
2, the utilization rate for improving pesticide reduces the usage amount of pesticide, reduces control cost.Electrostatic spray droplet size Generally at 45 μm or so, it can be effectively reduced mist droplet particle size, improve spectrum of fog drop uniformity, meet biological optimum grain-diameter theory, easily It is captured in by target, and more preferable to the penetrability of the targets such as plant strain canopy.Significantly increase the machine that droplet is contacted with pest and disease damage Meeting has doubled up prevention and control of plant diseases, pest control effect (improving 2 times or more by spraying than conventional under similarity condition).And finish is to insect Body wall has affinity, readily penetrates through body wall and enters in pest body, pest is made quickly to be poisoned.Dosage is than conventional spraying saving 30% or more.
3, smaller on water source, environment influence, reduce pollution of the pesticide to environment.Electrostatic spray spouting liquid is few, per acre only For 60~150mL, only routinely spraying more than one percent, and the suction-operated of electric field force reduces the drift of pesticide, makes agriculture Medicine utilization rate is high, avoids pesticide loss, reduces pollution of the pesticide to environment.
4, the electrostatic spray lasting period is long.Charged Droplet adsorption capacity on crop is strong, and comprehensively uniformly, spray pattern Height, it is firm that pesticide adheres on leaf, resistance of rainwater washing against, and the high boiling solvent in finish can effectively delay pesticide effectively at The degradation divided, drug effect are permanent.
5, work efficiency is high, and prevention and treatment is timely.Hand-held electrostatic ultra low volume spray improves 10~20 times of work efficiency than conventional by spraying, east Red -18 type power knapsack electrostatic sprayer can spray 20~30 mu per hour.
6, electrostatic spray uses matched electrostatic oil agent, without adding water, breaks out especially suitable for water scarcity, pest and disease damage category Property and occurring area is big, the occasion that must be administered on a large scale in the short time.
7, electrostatic spray is not likely to produce phytotoxicity to crop, and without obvious residual, the quality of crop can be improved.
Currently, preparing solvent used in electrostatic oil agent is heavy aromatics or two wires oil.Earliest electrostatic oil agent with a line oil or The charged particles that two wires oil is generated as cosolvent, agriculture breast 500# as conductive agent (CN1058505A) as solvent, medium alcohol Limited, conductivity is only up to 10-3μs·cm-1Rank.The electrostatic oil agent in two generations mainly has nitenpyram static oil agent, penta Azoles alcohol electrostatic oil agent, acetamiprid electrostatic oil agent, avermectin and chlorpyrifos dualistic combination electrostatic oil agent etc., these electrostatic oil agents Using heavy aromatics as solvent, conductivity 10-1μs·cm-1Rank (CN101518231A, CN101897331A, CN101578979,CN101578993).However, solvent heavy aromatics or two wires oil used in conventional electrostatic preparation are not only to environment Pollute it is larger, and generate charged particles it is limited, limit further increasing for deposition of the droplet on target.
Currently, the preparation of VM single dose mainly has missible oil, microemulsion, granule and aqueous emulsion etc., only Avermectin The electrostatic oil agent of element and chlorpyrifos mixture, and the electrostatic oil agent of VM single dose has not been reported both at home and abroad.
Summary of the invention
To solve the technical problems existing in the prior art, the purpose of the present invention is to provide a kind of avermectin electrostatic oil Agent and preparation method thereof.
On the one hand, the present invention provides glycol acetate and/or modified urethane in preparing pesticide electrostatic oil agent Application, the application is solvent as electrostatic oil agent.
Inventor is devoted for years in the research of pesticide electrostatic oil agent, aiming at the problem that solvent of traditional electrostatic oil agent, such as Two wires oil has disabled, and the conductivity of heavy aromatics is limited and environmental pollution is larger etc., carries out the electrostatic oil with excellent performance The research of agent solvent.By attempting a variety of common solvents, inventor has found that Ester is more suitable as the oil of electrostatic solvent Agent, however find through a large amount of comparative tests, the electrostatic solvent that the esters of different structure are prepared as solvent is in dissolubility, conductivity It differs greatly in terms of viscosity.Contain different number ester bond, different molecular weight size Ester, inventor by screening It was found that the two is used alone or mixing connection when the solvent of glycol acetate and modified urethane as electrostatic oil agent With the pesticide electrostatic oil agent of preparation can generate higher conductivity, lower viscosity, outstanding physical and chemical performance cooperation Electrostatic Spraying technique is in use, significantly improve the deposition on crops.
