The Best Backpack Sprayer Reviews: Reviews & Recommendations

The best backpack sprayer is a valuable tool that saves time and can put chemicals on grass, trees, and gardens to kill insects, improve the soil, and feed plants. New gardeners are often told to spray their yards to get rid of weeds and invasive species, but  not how. Even though you could spray an entire garden with just a spray bottle, backpack sprayers are a great way to get rid of weeds over a large grass area.

• Tank Capacity

Sprayers come with tanks that can hold anywhere from 2 to 7 gallons. Use a handle to move smaller sprayers and a wheeled cart to move the bigger tanks. Most people would say that a 4-gallon backpack sprayer is about average in size. The right backpack sprayers are those that fall somewhere in the middle of these two extremes in terms of weight. Typical jobs like fertilizing a lawn or spraying for bugs can be done with a 4-gallon tank in a yard between 5,000 and 10,000 square feet.

• Pressure Sprayer

Make sure your backpack has enough sprayer pressure to achieve the distance and hard-to-reach places. At least 40 PSI is required for most projects, but we prefer 60 PSI because it's easier to handle. You can choose options with up to 150 PSI if you need to go far.

• Comfort

When carrying up to 50 pounds of liquid solution on your back, you want to stay comfortable. Look for backpack sprayers with padded harnesses and even support for your lower back. Avoid things with thin straps that could dig into your shoulders and make you feel even worse.

2. Field King Max 190348 Backpack Sprayer

Best features

• Durable

• Include four nozzles

• High maximum psi

If you want excellent performance and comfort that lasts, the Field King Max is sure to give you both. It has the highest pressure of 150 psi, enough power for most jobs, and an internal pump structure that keeps leaks inside the tank. There are four nozzles: one that sprays in a stream-to-cone shape, one that sprays in a wide flat fan shape, one that sprays in a narrow flat fan shape, and one that sprays foam.

Even though you need to exercise  some muscle to use it, the Field King Max was the best manual backpack sprayer we tried, primarily because of its harness system. Although it lacks padding, it has a hip belt, sternum strap, and wide shoulder straps that didn't scrape into the shoulders while being tested. Compared to the other manual sprayers, it also had the smallest number of drips after letting go of the spray trigger. 

3. Field King 190515 Backpack Sprayer

Best features

• No pumping required

• Triple filtration system

• The 20V lithium-ion battery is rechargeable. 

A passionate amateur landscaper will be fond of  the Field King 190515 backpack sprayer's 4-gallon tank and 4-hour battery charge. Users can adjust the pressure from the preset 40 pounds per square inch (psi) to an even higher level, while the lockable shutoff on the wand helps prevent hand fatigue. The built-in handle and place to store the wand make it easy to move.

The Field King 190515 was the most accessible battery-powered backpack sprayer to carry, since  the shoulder straps and hip belt had a lot of padding. The lowest pressure rating was 40 psi, but that was still enough  to deliver a range of spray patterns, from a delicate mist to a coarse downpour of bigger droplets.

1. How many square feet can you cover with a backpack sprayer?

Your sprayer's tank capacity determines how much you can apply at a time. With a 4-gallon sprayer, you can cover an area of nearly 5000 square feet. 

2. Is it safe to use a backpack sprayer?

Pack sprayers are secure when properly packed with appropriate solutions, and care is made to protect the eyes, skin, and respiratory system.

As a precaution, the backpack comes equipped with a personal shield in case liquid spills out and is redirected back at the wearer. This isn't a big deal with water, but pesticides and herbicides could be dangerous if the sprayer is full.

3. How far can you get away with a backpack sprayer?

The sprayer's maximum pressure, nozzle type, wind direction, wind force, and spray wand angle all have a role in determining how far it can spray a liquid solution. Most backpack sprayers range 10 to 20 feet, while others may spray up to 30 feet. 

In conclusion, the best backpack sprayer is a flexible and time-saving way to put chemicals on gardens, trees, and lawns to kill bugs, improve the soil, and feed plants. We hope this post has been helpful  for you  in selecting one for your garden.
