Atomizer (Sprayer) is one of the gardening and farm equipment that is used to help the work such as watering plants and of course as a tool to provide fertilizer and pesticide spraying leaves for existing disease pests safely on plants. For the workings of the sprayer to be used as a tool for controlling pests and plant diseases, namely by mixing of pesticides to be used with water, of the pesticide active ingredient dissolved in water then we use to spray the plant (leaves, stalks, fruit) and spray targets (pest–disease). Efficiency and effectiveness of the spray tool is determined by the quality and quantity of the active ingredients contained in each grain gets sprayed with solution (droplets) attached to the target object and spray.
Sprayer is a tool/machine that serves to break up a liquid, solution or suspension becomes granular liquid (droplets) or spray. Pesticide applicator tool sprayer is indispensable in order for the eradication and control of pests and diseases of plants. Sprayer is also defined as a pesticide applicator tool is indispensable in order for the eradication and control of pests and plant disease &. The performance of the sprayer very determined suitability droplets the size of applications that can be issued in a specific unit of time so that compliance with the conditions of use of pesticide doses that will be sprayed.
From the results of several studies suggest that the type of sprayer that is widely used in the field is the type of hand sprayer (pump type), but the results are less effective, inefficient and easily corrupted. The results of the study conducted by the Department of agriculture in 1997 in several places in Indonesia shows that sprayer type carrying often suffered damage. The sprayer components often have damage include: tube leaking pump, shaft the shaft easily broken, leaking valves, rubber gasket is often torn, worn, screw the hose nozzle and burst, Contracting faucet sprayer easy carrying strap breaks, disconnect, connection las corrosion, etc. (Director General of food crops, 1977). In addition to the issue on the device the Prod, another problem is most pesticides that are applied are not appropriate (beyond) of the recommended dose and this one is caused by the design of the sprayer is lacking support applications (Mimin, et.al., 1992).
From previous research results can be known that performance sprayer electrostatics are better than any other type of sprayer, but need further modification mainly on power sources (batteries) so that the its droplet dispersion pattern and its expenditure actually controlled, fluid contact carrier materials (media contacts) that expensive considering not all chemicals can be applied using electrostatic sprayer. The other weakness is still not created the design of ergonomic (less heavy and flexible) so it was a bit difficult in the operational field. In addition the design of electrostatic sprayer needs to be modified considering the price or cost of production is still high when compared to other types of sprayer (especially the type of sprayer knapsack sprayer/carrying), both local and imported products. Research results Kusdiana (1991) and Roni Kastaman (1992) suggests that the actual type of sprayer that can be considered the most good and meets the criteria of the desired usage by users (particularly farmers) is the Microner type of sprayer or Electrostatic Sprayer.
Generally many users preferred criteria is criterion guarantees the availability of spare parts, safety in the use of tools, economical, capacity and practicality. Similarly, the conclusions of the study results Mimin et.al. (1992), namely that the sprayer is the best in terms of performance is pump electrostatic sprayer and worst of hydraulic sprayer. Pesticides used in crop cultivation are generally liquids and some are shaped like flour, used to control weeds, pests and diseases of plants. For applying liquid pesticides used so-called atomizer sprayer, whereas for pesticides used flour shaped tool called wheelbarrows. In its use of everyday peasants often encounter problems such as engineering usage, as well as repair and maintenance. Things like this will ultimately determine the level of efisisnsi and effectiveness in its use.
Based on the energy use of the atomizer atomizer with differentiated into hand power (hand sprayer), and atomizer with high pressure pumps. The performance of the sprayer very determined suitability droplets the size of applications that can be issued in a specific unit of time so that compliance with the conditions of use of the pesticides will be sprayed dose (Hidayat, 2001). From the results of several studies suggest that the type of sprayer that is widely used in the field is the type of hand sprayer (pump type), but the results are less effective, inefficient and easily corrupted. Results of a study conducted by the Ministry of agriculture in 1977 in several places in Indonesia shows that sprayer type carrying often suffered damage. The sprayer components often have damage include: tube leaking pump, shaft the shaft easily broken, leaking valves, rubber gasket is often torn, worn, screw the hose nozzle and burst, Contracting faucet sprayer easy carrying strap breaks, disconnect, connection las corrosion, etc. In addition to the issue on the device the Prod, another problem is the most recommended and this one is caused by the design of the sprayer is lacking to support the application.
The Function Of The Sprayer On The garden sector.
The main function of the sprayer is to break the liquid that is sprayed into small droplets (droplets) and distribute evenly on the protected object.
The special sprayer uses as follows:
Spraying insecticide to prevent and eradicate pests.
Spray a fungicide to prevent and eradicate the disease.
Spraying herbicides to prevent and eradicate weeds.
Spraying of liquid fertilizer.
Fluid squirt of the hormone on the plant for a specific purpose.
Purpose Of The Sprayer On The Agricultural Sector
In order to be able to perform calibration as well as determine the amount of solvent to certain cultivation requirements.
Type–the type of Sprayer Which are often used in the agricultural sector.
Sprayer for agricultural purposes known by 3 types of sprayer knapsack sprayer, namely, motor sprayer, and CDA sprayer.
Knapsack sprayer or spray tool known as the backs. Sprayer is most commonly used by farmers in almost all agricultural area of rice, vegetables, or garden.
Knapsack sprayer working principles:
Excluded from the solution tank is a result of the existence of air pressure through the pump’s power generated by the movement of the hand sprayers. At the time of the handle of the pump digerakan, the solution out of the tank towards the air tube so that the pressure inside the tube increases. This situation led to a solution of the pesticide in the tank was forced out through a.k.a. and further directed by the nozzle the spray target field.
The air pressure generated by the pump is kept constant temperatures, i.e. of 0.7 – 1.0 kg/cm2 or 10-15 Psi. The pressure of that obtained by means of pump as much as 8 times. To keep the pressure steady, pumping is done every 2-step pump must run use once heaving. Knapsack sprayer tank capacity varies in the range 13, 15, 18, 20 depending on the brand. Examples of knapsack sprayer Brands among others, Solo, Hero, CP 5, Matabi, Berthoud, and PB.
Sprayer type engines as propulsion pump which serve to remove the solution in the tank. How to use motor sprayer varies depending on the type and brand, the other in his arms on the back , are drawn with the vehicle, placed above the ground, brought the aircraft, and so on. An example is the mist blower sprayer motor power sprayer, and boom sprayer.
The advantage of using a motor sprayer especially very large capacity with a relatively short time, can penetrate the target although overgrown weeds and minimal labor.
The price is relatively expensive and the cost of use and treatment which is also expensive.
Not recommended on young plants because it was feared the drift damage plants
Motor sprayer should be treated routinely include servicing, replacement parts, etc.
Unlike the 2 types of sprayer before, CDA sprayer does not use air pressure to deploy the solution spray to spray the target, but rather based on the style of gravity and round disc.
The workings of the CDA sprayer is: the solution flows from the tank through the hose towards the nozzle, received by a round serrated disc (spining disc), and deployed in the direction of the field goal. use plate round by dinamo with 12 volt source power bater. The round disc of 2,000 rpm and granules coming out of uniform with a size of 250 microns. Size 250 microns is the optimal size to moisten the surface of the weeds. Based on the uniformity of the resulting granules form then the tool this spray called CDA (controlled Droplets Application).
