Backpack Sprayers Buyer’s Guide

We usually need Backpack Sprayers for taking care of our garden. It helps us to protect our plants from pest infestation and for keeping away certain diseases. To buy the right one, we need first to identify our purpose and review all of its components. Also, there are some other factors that we need to keep in mind while purchasing the best backpack sprayers. Check them out in the following.


The tanks hold different chemicals like insecticides, pesticides, and fertilizers. Home gardeners must opt for lightweight tanks of 2 to 4 gallons. However, professional landscapers have to make broad coverage. That is why they need a large holding capacity. So if you have a large farm or lawn, you need a tank with a greater retaining degree. Some tanks are made with plastic polythene, which enhances its durability, protects from UV, and makes it chemical resistant.


The types can either be manual or motorized. Its main function is to shift the liquid from the pressure unit to the wand from the tank. The manual ones are more affordable. Though the manual type has less wear and tear, the electric variety can offer 1.75 hours of constant spray. The latter also provides greater coverage. The electric ones cause less fatigue than manual Sprayers. They are also heavier.


The pumps have the function of taking the fluid to the pressure unit from the tank. They are of two types- piston and diaphragm. Diaphragm pumps are more costly. The piston pump can handle the pressure of 150 psi, while the diaphragm pump can take up 40 to 60 psi. The piston is not suitable for retaining wet powder, but the diaphragm can have different kinds of products.


The nozzles of the Backpack Sprayer are the essential components. There are usually three to four types: the stream nozzles, the cone spray, direct, and the flat fan. It controls the level of flow and distribution. Its tip is adjustable that maintains the spraying pattern. The nozzles can disperse 0.3 to 0.5 gallons in each minute.

Application wand

The application wand is a long shaft that maintains accuracy during the spraying process. You can also access tighter spots with the help of the application wand. It also makes sure that there is enough distance between the wand operator and the chemicals. That ensures the safety of the user. It also protects the operator from thorny plants.


Your comfort and safety are of the utmost importance when choosing a Backpack Sprayer. Professional landscapers require good and soft padded shoulder straps as they work to cover a larger area. Weight straps also ensure proper weight distribution. A comfortable harness is also important for landscapers. These factors ensure that it is safe and suitable for prolonged use. For extended periods, it must also have good lumbar support. The presence of the straps and harness makes it easier for the user to operate.


A Backpack Sprayer is an essential tool for gardening. You can choose your sprayer depending on the purpose of your use. The professional landscapers need it for extended periods. This is why they can opt for electronic sprayers with diaphragm pumps. Those who are home gardeners can choose manual sprayers with piston pumps. However, the piston pumps cannot accommodate products like dry herbicides. The Chapin International 63985 is the best option because of all the useful features that the product has. But if you are looking for the best budget, you can go for the Chapin International 61800. The Fieldking Professional 190328 also offers a good buy for an excellent overall budget.
