The existing preparation of the binary Pesticidal combination the present invention relates to mainly contains missible oil, aqueous emulsion, microemulsion and wetting powder etc.And the electrostatic oil agent of Avermectin and chlopyrifos 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 1: 10 to 1: 100, the composition that for example preferred proportioning is 1: 15,1: 24,1: 74.
The organic solvent that electrostatic oil agent 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 directly use 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, as more superior as the penetrability of plant strain canopy to target, therefore efficient especially with economize medicine, it is one of current 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, has reduced volatilization and drift.Droplet is tiny and even, meets " biological optimum grain-diameter " requirement, has significantly improved deposition.Electrostatic oil agent is directly used 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 the shower nozzle atomization, 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 atomization resistance, simultaneously, repulsive interaction generation between the same sex electric charge additional external and internal pressure contrary 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 be placed in liquid to the static high voltage, after the nozzle ejection, is Charged Droplet; (3) inductive charging method, be 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, in spatial movement, mutually repel, 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, to the positive and negative of crop, has improved the deposition of agricultural chemicals on the target crop, has improved the uniformity of agricultural chemicals deposition.The deposition of agricultural chemicals on crop surface improves more than 36% than conventional spraying, 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 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, in 45 μ m left and right, can reduce mist droplet particle size effectively, improves the spectrum of fog drop uniformity, meets biological optimum grain-diameter theory, is easy to be caught by target.When electrostatic potential is 20KV, mist droplet particle size reduces 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, be easy to penetrate body wall and enter in pest body, make 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 efficiency 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 oil agent, without adding water, is particularly suitable for the drought and water shortage area and uses.
7. electrostatic spray is difficult for producing poisoning to crop, without obviously residual, can improve the quality of crop.
