Background technology
Nitenpyram as active ingredient I is anabasine insecticide, has unique chemistry and biological property.Main Function is neural in insect, and insect cynapse acceptor is had the nerve block effect.Have efficient, low toxicity, interior suction and without four large advantages such as cross resistances, and insecticidal spectrum extensively, the lasting period is longer.Use safety, insect is difficult for producing resistance.The desirable substitute products of the 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.
Imidacloprid as active ingredient II is the nitro-methylene-type systemic insecticide, is the acting body of nicotinic acid nAChR ligands, disturbs the pest movements nervous system that chemical signal is transmitted malfunctioning, without the cross resistance problem.Be used for control sucking pest and resistant strain thereof.Imidacloprid is chloro nicotine insecticide of new generation, has wide spectrum, efficient, low toxicity, low-residual, and insect is difficult for producing resistance, to characteristics such as people, animal, plant and natural enemies securities, and have tag, stomach toxicity and the multiple drug effect of interior suction.After insect contact medicament, the nervous centralis normal conduction is obstructed, and makes its paralysis dead.Quick-acting is good, higher preventive effect is namely arranged in 1 day after medicine, and residual life reached about 25 days.Be mainly used in preventing and treating sucking pest.Can be used for preventing and treating the insects such as spiraea aphid, apple leaf curling aphid, black peach aphid, pear sucker, leaf roller, aleyrodid, liriomyza bryoniae.
The existing preparation of the binary Pesticidal combination that the present invention relates to mainly contains missible oil, aqueous emulsion, microemulsion and wetting powder etc.And the electrostatic spray liquor of Nitenpyram and Imidacloprid binary composition has no report both at home and abroad.
The mixing match of two kinds of active ingredients is I: II=1: 10 to 1: 200, be preferably the composition of 1: 10 to 1: 100.
The organic solvent that the electrostatic spray liquor is low by the screening volatility, flash-point is high, high to former medicine dissolubility, lower to chemical injury of crops, viscosity is low not to water, generally also not to other organic solvents, but is directly used with electrostatic sprayer during dispenser.Electrostatic spray makes the droplet of each ejection all with electrostatic charge, be easier to be caught by target, higher than general finish deposition, penetrability to target such as plant strain canopy is more superior, therefore 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 using method.And not containing the high volatile volatile composition in 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.The electrostatic spray liquor directly uses and need not be to water, is specially adapted to water scarcity, damage by disease and insect and belongs to fulminant and occur that area is large, occasion that must dispenser on a large scale in the short time.
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 shower nozzle atomizing, filled with electric charge by different charging methods, form 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 the good performances such as deposition efficiency is high, float of mist droplet scatters and disappears less, improve the ecological environment.Atomization of liquid mechanism more complicated under 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 is placed in liquid to the static high voltage, is Charged Droplet after the nozzle ejection; (3) inductive charging method is externally under the voltage electric field action, utilizes the electric field between electrode and medical liquid 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 even to the target vegetation, deposition is high.The droplet that electrostatic spray forms is with same sex electric charge, mutually repel in spatial movement, 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, the droplet quick adsorption has improved the deposition of agricultural chemicals on the target crop to the positive and negative of crop, has improved the uniformity of agricultural chemicals deposition.Agricultural chemicals improves more than 36% than conventional spraying at the deposition on 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.More much lower than conventional spraying at the deposition that vegetable protecting field adopts electrostatic spray, droplet to drop on the electrical insulator plastic film, can improve the deposition of droplet on plant, effectively utilize agricultural chemicals, reduce drift and be deposited in loss on plastic film.
2. improve the availability of agricultural chemicals, reduce the usage amount of agricultural chemicals, reduce cost accounting.The electrostatic spray droplet size generally about 45 μ m, can reduce mist droplet particle size effectively, improves the spectrum of fog drop uniformity, meets biological optimum grain-diameter theoretical, is easy to be caught by target.When electrostatic potential was 20KV, mist droplet particle size reduced approximately 10%, and the spectrum of fog drop uniformity improves approximately 5%.Significantly increase the chance that droplet contacts with damage by disease and insect, improved exponentially extermination of disease and insect pest effect (improving more than 2 times than conventional spraying under similarity condition).And finish has affinity to insect body wall, is easy to penetrate body wall and enters in pest body, makes insect poisoning fast.Dosage is saved 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 only 60～150mL, is only 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 is high adsorption capacity on crop, and comprehensively evenly, dispenser efficient is high, and it is firm that agricultural chemicals adheres on leaf, resistance of rainwater washing against, and the high boiling solvent in 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 spray liquor, need not to add water, is particularly suitable for drought and water shortage area use.
7. electrostatic spray is difficult for producing poisoning to crop, without obviously residual, can improve the quality of crop.
