This guide will help you find a weed killer that is user-friendly and efficient enough to tackle even the most stubborn weeds in your garden, lawn, or under sidewalks. 

However, most of the apparatus is pricey —especially if you seek a commercial weed killer sprayer with the best-in-class performance and durability. 

But we didn’t fail to consider everyone’s pocket. So we included other low-grade units that can still eliminate pesky weeds without damaging your plants. And more importantly, for pocket change.  

And for those with little or no idea about the topic, we’re going to start from scratch with what a weed killer sprayer is before progressing to the types, reviews, and what to consider before purchase. 

I hope you’re ready for this. 

What Is a Weed Killer Sprayer?

A weed sprayer is an apparatus for dispensing herbicide dedicated to weed killing, mostly in broadscale farming!

The sprayer creates many small droplets of herbicide, the most important component being nozzles that split liquid into smaller volumes and propel them through the air at targets.

But aside from applying herbicide, you can use it to spray fertilizer or any liquid pest control chemical. 

Types Of Weed Sprayers 

We both know how crucial it is to own a weed sprayer in your toolbox —especially if you’re a landscaper, gardener, or homeowner just trying to keep your lawn looking good.

But one piece of the puzzle that needs to be added is knowing the type of weed sprayer that suits your needs.

Here we’ll go over the common types of weed sprayers: 

1. Hand-held Trigger Sprayer

This type of sprayer is perfect for low-key jobs. I’m talking about spraying on indoor plants or the ones on your patio —as most people use them as a water mister.  

This unit features a plastic bottle ( is about a liter or so), a plastic cap with a nozzle, a plastic handle attached, and a squeeze pump, 

It’s pretty basic, very easy to carry around, and comfortable. 

Unfortunately, it’s not built for heavy-duty projects. 

2.Backpack Pressure Sprayer

More advanced than the hand-held version, the backpack pressure sprayer can handle anything from minor to heavy-duty. 

Backpack pressure units are more common with lawns, greenhouses, and orchard usage. 

And as the name suggests, it is a backpack with straps. You’re going to mount it on your back.

And this unit can carry up to 16 liters of liquid. The tanks come in cylindrical or broad, depending on your desired capacity. 

The spray nozzles and long wands project the mixture to an extended length compared to the hand-held sprayer. This enables you to target precisely without the weedicides touching something else.

You must mix the chemical in the tank in proper ratios, point the nozzle on the target, and then push the trigger. 

3. Tank Sprayer With A Hose End

Contrarily to the backpack unit, a tank sprayer will require a few learning curves, and your mobility is affected. 

The tank can hold up to 9 liters of liquid. However, you will have to attach a standard garden hose to the tank to the chemical container.

The bright side of the sprayer is it can mix the concentrate with water perfectly before dispensing. You just have to set the sprayer’s head for that. 

You can mix all things liquid, powder, or granules. Still, you can’t move freely with it for extensive projects. It is ONLY suitable for small sections. 

4. Trombone Sprayer

The trombone sprayer or slide sprayer takes it to a whole different level. 

It is a rare unit with crazy functionality that can bring down a tall tree. 

I’ll first have to give it credit for its farthest-reaching ability through the long wands; this makes them ideal for extensive projects. 

Although continuous pumping is a major drawback for users, it must also be consistent with its spray calculation.  

Aside from that, its industrial-sized tank can house up to 250 liters for commercial orchards and garden works.
