Description
Technical field
The present invention relates to Nitenpyram (active ingredient I hereinafter referred to as) and Buprofezin (active ingredient II hereinafter referred to as) for electrostatic spray liquor of the binary Pesticidal combination of active ingredient and preparation method thereof, belong to the pesticidal preparations field.
Background technology
Nitenpyram as active ingredient I 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 tree, 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.
Buprofezin as active ingredient II is the insecticide that coleoptera, part Homoptera and Acarina is had the lasting effect larvicidal activity.Can prevent and treat Cicadellidae, Delphacidae on the paddy rice effectively; Cicadellidae on the potato; Aleyrodidae on citrus, cotton and the vegetables; A red-spotted lizard section on the citrus, armored scale material and Pseudococcidae.Plant hopper, leafhopper, aleyrodid and scale insect class pest to Homoptera have special efficacy.
The existing preparation of above binary Pesticidal combination mainly contains missible oil, aqueous emulsion, microemulsion and wetting powder etc.And the electrostatic spray liquor of Nitenpyram and Buprofezin binary composition does not appear in the newspapers both at home and abroad.
Two kinds of mixing active ingredients proportionings are I: II=1: 10 to 1: 200, be preferably 1: 10 to 1: 100 composition.
The electrostatic spray liquor is low by the screening volatility, flash-point is high, to former medicine dissolubility height,, organic solvent that viscosity low lower to chemical injury of crops, 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 be caught by target, than general finish deposition height, penetrability to target such as plant strain canopy is more superior, so 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 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.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 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 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 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, 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 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, the target crop is covered evenly the deposition height.The droplet that electrostatic spray forms has same sex electric charge, in spatial movement, repel mutually, 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.More much lower at the deposition that vegetable protecting field adopts electrostatic spray, droplet to drop on the electrical insulator plastic film than conventional spraying, can improve the deposition of droplet on plant, effectively utilize agricultural chemicals, reduce drift and be deposited in 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, meets biological optimum grain-diameter theory, is easy to be 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 enters in the pest body, and insect is poisoned 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 only is 60～150mL, only is more than one percent of conventional spraying, and the suction-operated of electric field force reduced the drift of agricultural chemicals, makes agricultural chemicals availability height, 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 height, 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. the work efficiency height is prevented and treated 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 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.
