Description
Technical field
The present invention relates to one of them (hereinafter referred to as active ingredient) of emamectin-benzoate, Methomyl, chlopyrifos, lufenuron, indoxacarb, capillary or wherein both arbitrarily in conjunction with (hereinafter referred to as effective constituents A, B) for the monobasic of active ingredient or binary Pesticidal combination be used for ultra low volume liquids of preventing and treating the cotton noctuidae pests and preparation method thereof, belong to the pesticidal preparations field.
Background technology
The cotton noctuidae pests is the common insect on cotton, mainly contains prodenia litura, beet armyworm, cotton bollworm.Cotton region, the Huanghe valley, cotton region, the Yangtze river basin are injured heavier.In recent years, Xinjiang cotton also happens occasionally.The host also endangers the crops such as corn, peanut, beans, fruit and vegetables except cotton.Main control medicament has first dimension salt, Methomyl, chlopyrifos, lufenuron, indoxacarb, capillary etc., and the method for preventing and treating is mainly take foliar spray as main.
The existing preparation of the monobasic that the present invention relates to or binary Pesticidal combination mainly contains missible oil and suspending agent.And with emamectin-benzoate, Methomyl, chlopyrifos, lufenuron, indoxacarb, capillary one of them or wherein both are combined into arbitrarily the monobasic of active ingredient or the electrostatic spray liquor of binary Pesticidal combination, have no report both at home and abroad.
Summary of the invention
The purpose of this invention is to provide one of them of a kind of emamectin-benzoate, Methomyl, chlopyrifos, lufenuron, indoxacarb, capillary or wherein both are combined into arbitrarily the ultra low volume electrostatic spray liquor of the control cotton noctuidae pests of the monobasic of active ingredient or binary Pesticidal combination.
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.
The technical solution used in the present invention is:
