Why Does a Garden Needs Backpack Sprayer?

Backpack sprayers are the most important tool that every homeowner, gardener, and farmer must have in their toolshed. Plants, flowers, grass, and vegetable are more susceptible to disease. And you need a sprayer for pest infection, spider mites, killing weeds, insecticides, and more.

Most of the gardeners are also used backpack sprayers for fertilizing the lawn, cleaning the deck, spot spraying in the driveways, and cleaning carpets.

The backpack sprayer is beneficial because they help in controlling a specific type of problem that you are facing in your backyard. They deliver the solution quickly, efficiently, and economically. The sprayer allows you to spray uniform steam through different nozzles to areas under your feet and hard to reach.

Things to Consider Before Buying the Backpack Sprayer

Some of the things you need to consider before purchasing the right sprayer for your backyard.

Pound Per Square Inch (PSI)

PSI is the amount of spray that sprayer can through from the nozzle. The range of PSI is 10 to 150 depending on the model. It describes the effectiveness of the sprayer. That’s why it is important.

Little pressure produces an uneven spray that reduces the effectiveness of spraying. And excessive pressure is not beneficial for small yards. But if you have a large lawn and some hard-to-reach areas then the PSI above 70 is recommended.

Some backpack sprayers such as FloeZone Battery Powered Sprayer is also allowed you to change the PSI according to the requirements.  

Manual v Motorized

The backpack sprayer used an internal pump to draw fluid out of the chamber through a nozzle. For a manual sprayer, you need to pump the handle and the solution is conveyed upward. And the tool is ready for spraying. Manual sprayers are recommended for the small lawn areas. And also they are affordable.

But if you have a large lawn area then a motorized backpack sprayer would be best for you. They do the job quickly and reduce the pressure on your hand. They are generally expensive than manual backpack sprayers.

Delivery System

Backpack sprayers generally have two types of pump mechanisms: piston pump and diaphragm pump. Knowing the differences between the two will make it easier to select a sprayer and will help you spray more efficiently.

Piston Pump

Piston Pumps feature a cylinder housing in which a piston travels up and down to generate pressure. They can reach 60 psi but some of the models can reach up to 90 psi with an optional plug installed.

High pressure means small droplets. They are beneficial for use with contact herbicides and other products that might require smaller size droplets. But do not use it with bleach solutions because it can cause pump failure.

Piston pumps are beneficial for most homeowners because of their psi, simple design, and quick repair, and ease to use.

Diaphragm Pump

Diaphragm pumps feature a flat diaphragm inside of housing held together by twelve screws. Inside of it, a diaphragm travels up and down to generate pressure. Because there is no contact with a cylinder wall, as with piston pumps, these tend to be more durable.

They can generate up to 60 psi. They are beneficial for use with systematic herbicides and other products that might require large size droplets.

Nozzles

Backpack sprayers are different on the basis of types of nozzles. Most of the sprayers can attach different types of nozzles according to the job requirements. These nozzles control the amount of pesticide or fertilizer you spray per unit area.

Flat fan, cone sprays, and streaming nozzle are some of the most common nozzles that gardeners use for different functions. Each of them come with unique benefit and features.

Tank Capacity

Sprayers are available with a tank capacity of 2 to 7 gallons. But for a backpack sprayer, it is recommended to buy a maximum of a 4-gallon capacity sprayer. Because it will not fatigue you during the application. Because it will be light enough to carry. And would be enough for a 5,000-10,000 sq. ft. area.

But if you want a bigger one. Then buy a tow-behind sprayer or ATV sprayer.

Additional Features

Other features that may be considered while purchasing include wand length, anti-leak feature, built-in pressure gauge, extra padding, fold-way pump, shoulder strap, battery life and power, hardware quality, and more.

FAQs

What is the Working Pressure of Backpack Sprayers?

For homeowners, it is recommended pressure of between 40-60 psi. Because this coverage is sufficient for them. But for professional gardeners, it is recommended to buy a mode that provides up to 100 psi. More psi means more coverage.

It is also important to the calibrate sprayer for proper functioning. For calibrating the sprayer follow the manufacturer’s guidelines.

What Model Should You Buy? Motorized or Manual   

A motorized model is recommended only if you have a large area to treat. Because it automatically generates pressure and lowers your burden. But if you have a small lawn area. Then buy a manual backpack sprayer.

How to Deal with Leakage Problems in Backpack Sprayers?

Leakage may occur accidentally during the application. That’s why always buy a backpack sprayer that is equipped with an anti-leak feature.

Why Straps or Harness are Important in Backpack Sprayers?

Straps or harnesses accommodate the sprayer on your shoulder and chest. And they make the backpack sprayer more portable for the application. They uniformly distribute the weight and keep the hands free for the wand.
