Buying Guide

Backpack sprayers are essential products while spraying any chemicals in a farm or field. Thus, proper research is necessary to conduct before choosing a backpack sprayer. Although the above list of the best backpacks gives you an idea of what to pick, this buying guide enhances your decision-making process even more.

What is a Backpack Sprayer?

A backpack sprayer is a machine that allows the user to spray different liquids, water-soluble powders, chemicals like insecticides, pesticides, and many more on a wide area of land. It comes with a tank that stores the volumes of chemicals, a lever-operated hand pump to adjust the pressure, and a wand that can be attached with different types of nozzles. A backpack sprayer makes spraying easy for wider areas, and a maneuverable wand reaches hard to spray regions. It is a tool/machine that is portable and allows the spraying of liquids and chemicals on a wide variety of lands.

Why Does a Gardener Need a Backpack Sprayer?

A backpack sprayer is a convenient mechanism that allows the spread of different fluids like chemicals usually used in gardens and lawns like weed killers, herbicides, and insecticides. However, specific regions in a garden are hard to spray or some areas that need a calculated amount of spraying to avoid any damage to the plants. That’s when a backpack sprayer comes to the rescue. It is quick, portable. A thin wand reaches narrower regions and different nozzles to regulate and circulate the spray as per requirements. That’s the reason why a backpack sprayer is a need for avid gardeners.

Piston vs. Diaphragm Backpack Sprayer

The most considerable difference between a piston and a diaphragm sprayer is the pressure each can handle. Piston Sprayers can usually handle up to 90 PSI, and Diaphragm sprayers reach up to 60 PSI. Higher PSI allows a larger size of a droplet and vice versa for a diaphragm backpack sprayer. Piston sprayer tanks cannot be filled with strong or harsh chemicals but only herbicides, weed killers, and insecticides. However, you can use it with water-soluble fluids, powders, or bleaches on the flip side. Using the opposite kind of liquids or fluids in either type of sprayers could cause damage to the pump.

How to Calibrate a Backpack Sprayer?

Backpack sprayers are easy to use, but they will only give you optimal results if calibrated properly. A lot of precision goes into calibrating a sprayer. You need to know a few statistics before calibrating, those are,

  • Size of the area to be sprayed.
  • Amount of water you would need to spray the area.
  • Amount of chemical liquid or fluids to use on the area.

These statistics are necessary to prevent spraying too little or too much of the chemical on the area. The speed of walking while spraying also becomes a secondary consideration as it determines the pressure and coverage time. The type of nozzle also determines uniformity and the amount of fluid to be let out of the tank in one go. Once these parameters are fulfilled, move on with the calibration process.

  • Select the type of nozzle required.
  • Spray water on the area you wish to spray and check the uniformity of the stream.
  • Once you achieve a desirable stream. Start spraying from a proper spot maintaining the speed and the position of your hand while spraying.
  • Once the tank is empty, stop and make sure you mark the spot.
  • To determine the area covered, calculate the length in square feet by multiplying the length and width of the area.

Now, calculate the volume of gallons by dividing every gallon sprayed by the area. After achieving all these statistical data, you can easily determine the volume of pesticide needed for the area you desire to spray.

How to Use a Backpack Sprayer?

Backpack sprayers are used after examining the field or land that needs to be sprayed. After following the above calibration steps, you would need to make sure that you appropriately decide the type of nozzle and the pressure that needs to be maintained to spray the area.

  1. Wear the backpack sprayer and consistently walk on the field without changing the position of your hand while spraying.
  2. Use the valve on/off to shut the spraying process in case of exhaustion.
  3. Do not forget to mark the spot you left from.

Types of Backpack Sprayers


Manual or handheld backpack sprayers are the most commonly used sprayers in the market. A simple reason being their affordability. As there is no mechanical assistance, it makes a manual backpack sprayer lighter and also cheaper. In addition, manual sprayers are equipped with a hand pump that allows the constant release of chemicals and maintains constant pressure.


Undoubtedly, the addition of technology adds the ease of using a sprayer. However, it also makes it extremely expensive in comparison to manual sprayers. This kind of sprayer is recommended for use in larger regions. It is faster and more convenient in comparison to the handheld backpack sprayer.

Sprayer Parts


Various types of nozzles are compatible with the hose to get the desired stream. You can change or adjust it as per user requirements. Every single type of nozzle has a set of perks and is usable in different situations. There are a few types of nozzles from a flat fan, cone, streaming, and more made of various materials, including brass, steel, and plastic.


A backpack sprayer wand is a long steel/plastic tube attached at the tip with a hose to attach the nozzle. This part of the sprayer allows a calculated stream of chemicals or fluid sprayed around the area.


A backpack isn’t a backpack without straps. Most of the mentioned products in our list come with premium quality shoulder straps attached to the tank, which can be easily worn, making the sprayer portable and comfortable. A thick padded set of straps is necessary as spraying takes a long time, leading to injuries and back pain.


The pump in a sprayer is the main component as it allows the flow of chemicals and maintains the pressure in the tank. There are broadly two types of pumps. One is a piston, and the other is the diaphragm. Most are deceptively different with their pressure scale, repairability, and also liquid compatibility.

What to Use to Clean a Sprayer Tank?

Smaller parts of the sprayer tank like the hose and the nozzles should be cleaned with normal water. To avoid chemical reactions inside the tanks, people use dish soap liquid with warm water to clean the tank. Cleaning other parts like the pump can be done by damping a semi-wet cloth on the same, and cleaning other parts is a fairly straightforward process, just by rinsing them under clean water.

Backpack Sprayer Tips and Tricks

From choosing a backpack sprayer to using it, many tips and tricks will assist you in getting the best outcome for your bucks.

  • When it comes to spraying a small garden just with water or non-corrosive fluids or spray painting a wall in your house, the type of pump you would use is the piston.
  • While working with corrosive chemicals like herbicides and insecticides, a diaphragm pump is useful.
  • The nozzles also have specific uses with differing shapes and sizes. The narrower tip of the nozzle allows spraying in one particular place and hard-to-reach areas like a cone nozzle.
  • A broader or wider nozzle should be used for spraying over a large portion of land like a hollow and a flat fan nozzle.
  • Another tip is to predetermine the seasonality of your region to ensure spraying in a pre-emergent or a post-emergent environment.

What to Look for When Buying a Backpack Sprayer?

There are various things to take into your account before getting yourself the best backpack sprayer. And those factors are as mentioned below:


There are two types of backpack sprayers, manual and motorized. Usually, manual backpack sprayers are also known as handheld sprayers. A manual sprayer requires more effort and time because of its hand-operated pump to maintain flow. However, the motorized backpack sprayer is easy to handle, convenient, and works fully on technology. One thing that defines their purpose is the difference in prices; manual sprayers are cheaper and vice versa for motorized sprayers.


One of the most important features to look out for is including nozzles with the sprayer. Despite their small size, nozzles pose to be an integral part of a weed killer backpack sprayer. Look out for including at least 2 or 3 nozzles like the flat fan, cone spray, and streaming nozzles. While they are extremely cheap compared to the other parts, they are really necessary for a controlled and calculated spraying process.


The pump is the ultimate component in every backpack sprayer. It is responsible for pushing out liquids from the tanks promptly to ensure continuous flow. There are broadly two types of pumps, piston and diaphragm pumps. The fundamental difference between the two is the pressure. Piston pump maintains 90 PSI while Diaphragm pump maintains 60 PSI. A diaphragm pump is more expensive than a piston pump, but piston pumps cannot hold heavier fluids like insecticides and herbicides.

Price and Safety

The price of the sprayer should be affordable and yet provide great features. However, most cheap sprayers are less durable and strong, and they can wear off sooner than expected. The price range for a 4-gallon tank backpack sprayer should be between $80 to $125. In addition, various safety features like thick padded shoulder straps and gentle grip on a manual pump are necessary for backpack sprayers.
