Description
Technical field
The present invention relates to a kind of nitenpyram static oil agent and preparation method thereof, belong to the pesticidal preparations field.
Background technology
Nitenpyram (nitenpyram) is an anabasine insecticide, has unique chemical and biological property.Mainly act on the insect nerve, insect cynapse acceptor is had the nerve block effect.Have efficient, low toxicity, interior suction and do not have four big advantages such as cross resistance, and insecticidal spectrum extensively, the lasting period is longer.Safe in utilization, insect is difficult for producing resistance.Be the desirable substitute products of conventional pesticides such as Imidacloprid, Acetamiprid.Nitenpyram can be widely used in paddy rice, fruit tree, vegetables and tea; Prevent and treat various plant hoppers, aphid, thrips, trialeurodes vaporariorum, Bemisia tabaci, leafhopper etc.; The insect that conventional pesticides has been produced resistance has remarkable control efficiency, is one of nicotinoids agricultural chemicals last word.
The existing preparation of Nitenpyram mainly contains aqua, pulvis, granule, solvable pulvis, solvable granula and soluble concentrate etc.And nitenpyram static oil agent does not appear in the newspapers both at home and abroad.
Electrostatic oil agent through the screening volatility low, flash-point is high, to the organic solvent that former medicine dissolubility is high, lower to chemical injury of crops, viscosity is low, not to water,, but directly use during dispenser with electrostatic sprayer generally also not to other organic solvents.Electrostatic spray makes the droplet of each ejection all have electrostatic charge; Be easier to caught by target; Higher than general finish deposition; Penetrability to target such as plant strain canopy is more superior, thus efficient especially with economize medicine, it is one of present target hit rate is the highest, environmental pollution the is minimum formulations of pesticide and method for using.And not containing the high volatile volatile composition in the droplet, its size does not have significant change with quality from leave facility arrival target process, reduced volatilization and drift.Droplet is tiny and even, meets " biological optimum grain-diameter " requirement, has significantly improved deposition.Electrostatic oil agent directly uses and need not be to water, is specially adapted to water scarcity, damage by disease and insect and belongs to fulminant and big, the occasion that must dispenser on a large scale in the short time of area takes place.
The electrostatic spray technology is that applying high voltage static is set up an electrostatic field between shower nozzle and spraying target; And agricultural chemicals liquid is flowed through after the shower nozzle atomizing; Filled with electric charge through different charging methods, formed colony's charged droplets, then under the synergy of electrostatic field force and other external force; Droplet is done directed movement and is adsorbed on each position of target, reaches good performances such as deposition efficiency height, float of mist droplet scatter and disappear less, improve the ecological environment.Atomization of liquid mechanism more complicated under the electrostatic field; It has been generally acknowledged that: electrostatic interaction can reduce surface tension of liquid, reduces the resistance that atomizes, simultaneously; Repulsive interaction generation between the same sex electric charge additional external and internal pressure opposite with surface tension is poor, thereby improves fogging degree.
The droplet charging has three kinds of modes: (1) corona charging method, utilize the electrostatic high-pressure corona to make droplet charged; (2) contact mise-a-la-masse method directly places soup to the static high voltage, after the nozzle ejection, is charged droplet; (3) inductive charging method is externally under the voltage electric field action, utilizes the electric field between electrode and soup jet to make droplet charged.
The electrostatic spray technology has the following advantages:
1. electrostatic spray has the effect of outflanking, point effect, penetration effect, and the target crop is covered evenly, and deposition is high.The droplet that electrostatic spray forms has same sex electric charge; In spatial movement, repel each other, do not condense, the induction of charged droplet makes the outside of crop produce the charges of different polarity; Under the effect of electric field force; Droplet is adsorbed onto the positive and negative of crop fast, has improved the deposition of agricultural chemicals on the target crop, has improved the uniformity of agricultural chemicals deposition.Agricultural chemicals improves more than 36% than conventional spraying at the deposition on the crop surface, and leaf back side agricultural chemicals deposition is tens times of conventional spraying, and crop top, middle part and root agricultural chemicals deposition distributing homogeneity all are significantly increased.Adopt electrostatic spray at vegetable protecting field, the deposition that droplet drops on the electrical insulator plastic film is more much lower than conventional spraying, can improve the deposition of droplet on plant, effectively utilizes agricultural chemicals, reduces drift and is deposited in the loss on the plastic film.
2. improve the availability of agricultural chemicals, reduce the usage amount of agricultural chemicals, reduce the control cost.The footpath generally about 45 μ m, can reduce mist droplet particle size effectively in the electrostatic spray droplet volume, improves the spectrum of fog drop uniformity, and it is theoretical to meet biological optimum grain-diameter, is easy to caught by target.When electrostatic potential was 20KV, it is about 10% that mist droplet particle size reduces, and the spectrum of fog drop uniformity improves about 5%.Significantly increase the chance that droplet contacts with damage by disease and insect, improved extermination of disease and insect pest effect (similarity condition improves more than 2 times than conventional spraying down) exponentially.And finish has affinity to insect body wall, is easy to penetrate body wall and gets in the pest body, and insect is poisoned fast.Dosage is practiced thrift more than 30% than conventional spraying.
3. little to water source, environmental influence, reduced the pollution of agricultural chemicals to environment.The electrostatic spray spouting liquid is few, and every mu is merely 60～150mL, is merely more than one percent of conventional spraying, and the suction-operated of electric field force reduced the drift of agricultural chemicals, makes the agricultural chemicals availability high, has avoided the agricultural chemicals loss, has reduced the pollution of agricultural chemicals to environment.
4. the electrostatic spray lasting period is long.Charged droplet high adsorption capacity on crop, and comprehensively evenly, dispenser efficient is high, it is firm that agricultural chemicals adheres on leaf, resistance of rainwater washing against, and the high boiling solvent in the finish can effectively delay the degraded of pesticide active ingredient, and drug effect is permanent.
5. work efficiency is high, and control in time.The hand-held electrostatic ultra low volume spray improves 10～20 times of work efficiency than conventional spraying, and Dongfanghong-18 type power knapsack electrostatic sprayer per hour can spray 20～30 mu.
6. electrostatic spray adopts supporting electrostatic oil agent, need not to add water, is particularly suitable for the drought and water shortage area and uses.
7. electrostatic spray be difficult for to produce poisoning to crop, does not have obviously residually, can improve the quality of crop.
