Sprayers are fully integrated, mechanical systems, meaning they are composed of various parts and components that work together to achieve the desired effect, in this case: the projection of the spray fluid. This can be as simple as a hand sprayer attached to a bottle that is pumped and primed by a spring-lever, tube, and vacuum-pressure; or as complex as a 150 foot reach boom sprayer with a list of system components that work together to deliver the spray fluid.


For more complex sprayers, such as agricultural sprayers, common system components include: the spray nozzle, sometimes with a spray gun, fluid tank, sprayer pump, pressure regulators, valves and gaskets, and fluid plumbing.[2] The sprayer pump can be just as important as the sprayer type itself as there are many sprayer pump design types with various construction materials, inlet/outlet sizes, and performance specifications. Common sprayer pump types include diaphragm, centrifugal, and roller pumps.[3]

Agricultural sprayers come in various design types, sizes, equipment and performance specifications. They range from small spot-spraying machines to very large sprayers with extensive land and plant coverage. Agricultural sprayers have been engineered to optimize their applicability and performance for the many purposes that the machines are put to, whether being used on crops, vegetation, or soil. Agriculture sprayers are often used for applying water and water/chemical solutions containing acids or caustic materials for crop-performance or pest-control; i.e. fertilizers and pesticides.[4]

There are a number of agriculture sprayers designed for spraying applications and designed to be versatile and suitable for various uses from spot applications, gardens, crops, row crops, crop trees, fruit, groves, vineyards, perimeter maintenance, livestock needs, weed control, pastures and rangeland. Self-propelled sprayers help farmers improve spraying efficiency and productivity while taking full advantage of every minute they have in the field.[5]

Improperly calibrated pesticide spraying equipment may cause either too little or too much pesticide to be applied. This free mobile app was created to aid in the proper calibration of spraying equipment. Simply select the type of sprayer you want to calibrate (Broadcast or Banded), insert values in each input box, select what you want the app to calculate (Volume/Area or Catch/Nozzle), and tap 'Calculate'. Each input's units can be customized by tapping the units. Sprayers can be saved with user-defined names.

"Calibration" simply means determining the output of a sprayer so a known amount of spray solution is applied to a given area. Applicators must know this if they wish to apply an herbicide at a specific dosage, which is described as the amount of product per given area (e.g., ounces or quarts per acre). Failure to calibrate spray equipment can result in misapplication of herbicides, repeat applications, damaged nontarget plants, excess costs, and environmental concerns.

The amount of spray applied to an area will depend on walking speed, spray pressure, spray swath width, and the spray tip selected. If any one of these variables changes, the amount of spray applied per unit area changes and the sprayer must be calibrated from the beginning. Each applicator may have a different walking speed, regulate pressure differently, and have a different idea of what adequate coverage looks like. Therefore, it is important to have each applicator calibrate.

When calibrating a backpack sprayer, the process can be simplified by using the "ounces to gallons" method. With this method, the amount of spray, measured in ounces, converts directly to gallons per acre. It is based on making the calibration application to an area of 1/128 acre, or 340 square feet (43,560 square feet per acre 128 = 340 square feet).

When measuring the time required to treat the calibration area, operate the backpack as you would when spraying in the field. Adjust the spray nozzle to the desired setting, hold the wand at a consistent height above the vegetation, and pump the sprayer to the normal operating pressure. Record the time it takes to cover the distance. Do this several times to get a reliable average. If more than one applicator is doing treatments, then times must be recorded for each applicator.

Once you know how long it takes to treat the calibration area, the next step is to determine how much liquid is applied in that time. Use a measuring cup to collect spray solution from your sprayer for the same time it took to spray the calibration area. This amount, in ounces, will equal the gallons per acre of your application. If it takes 15 seconds to cover the calibration area, then collect spray water from your backpack in a measuring cup for 15 seconds, and measure the volume in ounces.

When collecting, it is important to pump the sprayer the same way as when making the test application; otherwise, the flow rate will differ and calibration will be less accurate. To get a reliable average volume, repeat this process two or three times to get the average nozzle output.

Since we are using a backpack sprayer, we want to mix smaller amounts. The first step is to determine how much herbicide to add to each gallon of solution. This is a division process that gives the answer in ounces per gallon. Simply divide the ounces of herbicide recommended per acre by the gallons of mix applied per acre.

Now you are ready to measure out the amount of herbicide needed, mix it in your sprayer, and begin treating. Be sure to use the same walking speed, spray pressure, spray swath width, and spray tip used when calibrating. This will ensure that the herbicide is being applied at the proper rate.

The most common use of a backpack sprayer will likely be to "spot" treat undesirable weeds that are scattered about a site. Spot treatments are used to treat discrete targets, such as a single shrub, as well as patches of continuous vegetation. Spot herbicide treatments are commonly used to control invasive shrubs such as multiflora rose, shrub honeysuckle, autumn olive, Japanese barberry, and privet. Calibrating for these types of treatments allows the applicator to estimate spray coverage so the mix will be effective without over- or underapplying.

In our example, we started with 40 ounces of water in the graduated container and had 5 ounces left after the sprayer was refilled to the starting level. Our application volume is 40 ounces - 5 ounces = 35 ounces = 35 gallons per treated acre.

However, since we are using a backpack sprayer, we want to mix smaller amounts. The same formula used for band applications applies here. To determine the amount of herbicide to mix in each gallon, simply divide as shown below to get your answer in ounces of herbicide per gallon of spray solution.

To make a basic wall, build the wall to the desired dimensions out of Wooden Scaffolding. Switch to your loaded CF sprayer, walk up to the wall and [Right Click]. Scaffold blocks should fly everywhere and in their place should be Construction Foam.

Before calibrating a sprayer, service the entire unit. Check that all nozzles are the same size and not worn. Check for uniform nozzle output and pattern and determine exactly how much liquid the sprayer tank holds. Install a pressure gauge on the boom to determine actual pressure at the nozzles.

Nozzle Output and Pattern - Check for uniformity of nozzle output and the spray angles, spacing and height are consistent. To check for uniform nozzle output, install the selected nozzle tips and check to be sure the tank is clean. Then partially fill the tank with clean water and operate the sprayer at a pressure within the recommended range. Place a container, such as a quart jar, under each nozzle and check to see whether all the jars fill at about the same time (Figure 6). Replace any nozzle tips with an output that significantly varies compared to the output of the rest of the tips, have an obviously different fan angle or have a non-uniform appearance in spray pattern. The rule of thumb is nozzles with flow rates greater than 10% above a new nozzle of identical make should be replaced. 041b061a72
