Best Backpack Sprayer for Efficient Pesticide Application

Gardening may be fun and relaxing, but some aspects are not that enjoyable. However, with the right tools, you can make it a little easy. One of the easiest ways to garden and get rid of weeds from your garden is to use the best backpack sprayer to apply pesticides. Backpack sprayers are not only used to spray pesticides, but they are also used to apply fertilizers, and even on construction sites, you can use them to apply chemicals like paint removers.

Backpack sprayers are the best for handling heavy-duty tasks and in large companies where precision and evenness are required. These sprayers have different nozzle sizes that ensure that there is accuracy. With the best backpack sprayers, you can access the hard-reach places and spray easily without straining for too much.

When handling harsh chemicals, a good backpack sprayer will always keep you safe from coming into contact with the chemicals. There are different backpack sprayers, and we shall go through them before we look into the best backpack sprayer. They differ depending on the type of pumps they use and are available in three main types, which include;

(i). Manual Backpack Sprayer

Manual sprayers are the most widespread backpack sprayers. They are simple and easy to operate. You only need to move the handle to generate pressure and spray. Because they are simple, they are easy to repair and do not require a lot of work.

(ii). Gas Backpack Sprayer

Gas backpack sprayers are the most powerful, and you can use them to spray large areas effectively and within a short time. They are gas-operated and are expensive to operate, and are even higher priced. These types of sprayers are ideal for large-scale projects and are more effective for big landscaping companies. Gas sprayers are suitable for applying contact-based products and not liquids that need heavy droplets due to their high Pounds per Square Inch (PSI) output.

(iii). Battery-Powered Backpack Sprayer

Battery-powered backpack sprayers have a constant PSI that you can adjust. The battery allows this backpack sprayer to generate pressure without the need to create pressure with a pump. One disadvantage of this sprayer is that it is heavy due to the weight of the battery. They are also delicate as the battery may be compromised if water gets into the compartment.

Now that you know the different types of sprayers, I would like to take you through the best backpack sprayers and their buying guide.

Factors to Consider Before You Buy the Best Backpack Sprayer

There are many backpack sprayers in the market, and you may not know what to look for when buying one. Each one is different and has various features that make it unique in its way. Therefore we will discuss the features that you need to look for when buying the best backpack sprayer. There are various features that you may need to consider, and they include;

a). Material

The material used in making a product determines if it can hold harsh chemicals or not. If you need a sprayer that will carry all your chemicals without corroding them, ensure that its material is corrosion-resistant. It also needs to be U.V. resistant to withstand long hours of being used in the sun.

b). Wand and Nozzles

Sprayers have different wand lengths, which also vary according to the materials used to make them. A good backpack sprayer needs to have a long and flexible spray wand to make spraying easier and less hassle-free. A flexible wand is easy to use as you can extend it to reach a higher place to spray all the regions that need spraying.

c). Capacity

Most backpack sprayers have four-gallon tanks, which is more than enough if it is for home use. However, if you want your sprayer for professional services, you will need a tank with a higher capacity. Some tanks can hold up to 7 gallons of liquid. However, carrying such a large amount of chemicals may make you get tired fast before you spray a large area. Therefore, you may need to manually calibrate your backpack sprayer to know how many chemicals you need to mix, and it will save you from carrying excess liquids.

d). Pounds per Square Inch

PSI is the measurement unit used to measure the pressure that a sprayer can generate. If the PSI of pressure is high, the liquid droplets will be more divided after passing through the nozzle. Different products need different PSI depending on the droplet size. Most professional backpack sprayers range between PSI of 30 on the lower sider and PSI of 150 on the upper end.

e). Type of Sprayer

As discussed earlier, we saw different types of sprayers, depending on their power source. A battery-powered pump sprayer uses batteries to pump the liquid, and they are quieter, more friendly to the environment, and more efficient. They also require less maintenance. On the other hand, you cannot use a manual pump to spray a large area as they are slow and easy to use.

f). Straps and Lumbar Support

You cannot easily get a backpack sprayer designed to carry less than four gallons of water. So if you carry a backpack sprayer full of four gallons of liquid and the weight of the sprayer itself, you can see that it is a lot. That is why the best backpack sprayer needs to have proper straps and lumbar support. A good feature is the waist strap, which helps distribute the weight across your hips, not to weigh you down. It also prevents you from experiencing back and shoulder pains.

Whether you choose to go with a battery-powered backpack sprayer or a gas sprayer, or even a manual sprayer, that is all dependent on you. However, you need to ensure that the product you are buying is worth it and provide the necessary services. I hope you make the right choice.
