Description
Technical field
The present invention relates to technical field of pesticide, and in particular to Biphenthrin electrostatic oil agent and preparation method thereof.
Background technique
Biphenthrin (bifenthrin) is a kind of pyrethroid Insecticidal and acaricidal agent efficiently synthesized.With knocking down
The features such as effect is strong, wide spectrum, does not move efficiently, quickly, in the soil, safer to environment, long residual effect, with action of contace poison and
Based on stomach poison function, no systemic action.It can be used for preventing and treating bollworm, pink bollworm, tea geometrid, Euproctis pseudoconspersa, apple or the red spider of hawthorn
The small moth of spider, small heart-eating peach worm, vegetable aphid, cabbage caterpillar, dish, phyllocnistis citrella stainton etc..
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 spray finish 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 spray formulation are not only right
Environmental pollution is larger, and the charged particles generated are limited, limit further increasing for deposition of the droplet on target.
Currently, the existing preparation of Biphenthrin mainly has missible oil, aqueous emulsion, microemulsion, suspending agent etc., and Biphenthrin electrostatic
Finish has not been reported both at home and abroad.
