A sprayer for weed killer is a tool used to apply herbicides in an area. It can be either a handheld device or mounted on machinery, and it sprays the chemicals directly onto vegetation. The most common type of equipment uses pressurized liquid from tanks that are loaded with the product being sprayed. 

When activated, these systems release water mixed with glyphosate or other similar chemical compounds to effectively kill weeds and unwanted plants without harming nearby crops or existing turfgrass.

Sprayers for weed killers come in many varieties designed specifically for different purposes, such as: 

  • applying pesticides to large areas like fields, lawns, gardens and driveways; targeting individual weedy patches found throughout yards; 
  • killing invasive species lurking within natural habitats; 
  • limiting damage to ornamentals and other crops; 
  • creating a perimeter barrier along fences to keep animals from entering an area;

Choosing the best sprayers for weed killers can be difficult. There are so many different options on the market, and if you’re not careful you might end up with one that’s either too powerful or not powerful enough! This guide will help you to choose a weed killing sprayer that is perfect for your needs, whether it be small yards or large fields of weeds. Follow the expert tips and reviews to find the best sprayer for weed killer that’s right for you.

The Buyer’s Guide

Sprayer Types:

Backpack sprayers

The backpack sprayer is the most popular type of sprayers for weed killers. They’re easy to use and comfortable, but they have their limitations like taking a long time to fill up with products, which can be difficult for larger jobs. 

The downside: you need two hands! One hand needs to hold the nozzle while going around your yard spraying in every crevice where weeds may grow again next year. This means that one hand won’t be free for other tasks like carrying supplies or doing something else at the same time. It also takes quite some practice before it becomes second nature how much pressure should be applied when using this type of sprayer – too little pressure will leave black specks on plants, too much merely wastes product; both are frustrating and inefficient.

Beyond that, this type of sprayer is the best for large jobs where spraying is done in sections with breaks between them and it’s not necessary to continuously move around while spraying. Backpack sprayers also work well when you’re applying herbicides on bigger plants like fruit trees or bushes, as they are easy to carry up a ladder without spilling any product at all. For smaller projects – such as weeding your garden bed or putting down weed-killer in your flower beds – backpack sprayers aren’t ideal because they’re hard to maneuver and may make things more difficult than if you used a handheld one instead.

Tank pump sprayers

Tank pump sprayers are also the popular type of weed killer applicators. They work by creating a vacuum that draws in and holds enough pressure for spraying while storing it in a tank mounted on top of the unit. 

If you want to purchase one, you should keep these considerations in mind:

  • Tank sizethe bigger the better when looking at capacity (up to 500 gallons). It also keeps your pressure consistent since there’s more stored inside. This means less pumping required from you, which can reduce fatigue or soreness after use. Smaller tanks don’t have this benefit though because they need constant refills so users always know they’re running out over time before their job is done;
  • Pressure controls are often present to adjust the pressure of your spray. This is so you can control when and how much product comes out for each area that needs it, or even prevent accidental overspray if desired with high-pressure settings;
  • Control handle – the other thing about tank pump applicators is that they usually have an attached handle. This makes them easier to use than handheld models because they’ll always be in a comfortable position whether standing up straight or leaning from side to side as needed while spraying around plants at different heights;

Handheld pump sprayers

Handheld pump sprayers are the most common type of weed killer applicator. They can be found at any hardware store and come in a variety of shapes, sizes and colors. All of them work similarly by drawing up liquid from their container through a tube into an optional nozzle at medium pressure.

They usually cost less than $25. Handheld pumps typically hold 2 gallons of liquid that means you’ll need to refill often if spraying large lawns or fields. 

This might not be ideal for high volume weeds but is suitable for small jobs like greenhouses, patios, porches or decks where one gallon will cover about 200 square feet when used as directed (one quart per 20 square feet). The nozzle on these types of weed killers range from fine mist to heavy stream depending upon your preference – so make sure you purchase accordingly.

Tow behind sprayers

Tow behind sprayers is the best option if you need to apply weed killer in a continuous line. Tractor or ATV can tow these types of units. They have either an open channel that is pulled over the ground or a large circular tank with rotating wheels that evenly distributes fertilizer as it moves forward. The wheels on this type of unit release chemicals onto the soil surface so they do not leave any traces once they pass through.

The most common match-up for these machines is with tractors because their pull power equals many hours of spraying time without worrying about stopping and refueling your machine when you get low on fuel. Tow behinds also work well for applying liquids across acres of land quickly since there’s no way to control the application rate other than altering how fast you are going.

The downside to these machines is that they can’t be used on slopes greater than 15 degrees and may have trouble getting over uneven terrains, such as rocks or branches in the ground. If there’s a large area with hillsides then this type of unit probably isn’t your best option. There are also some limitations for what size tractor can tow them. Most only work with tractors above 40 horsepower or those who use three-point hitch attachments to connect it to the back end of their machine. The weight limit for these units ranges from 500 pounds (smaller models) up to 1100 pounds (larger ones).

Aerator sprayers

It will typically have a rotating disc at the end that helps distribute the liquid evenly and soften it. This is one of the best types for chemical-based herbicides as they are more gentle on the plants than other methods, which means you’ll need less in order to treat your lawn with this technique. 

They also allow water droplets to be sprayed when there is not enough pressure – so if you live near an area where rain doesn’t often come, then these can help maintain healthy grass without having too much time between watering sessions. However, because they don’t cover large areas well, you might find yourself spraying multiple times with this type of sprayer.

Aqua jet nozzle sprayers

Another good option for weed killer is the aqua jet nozzle, which usually has a narrower and powerful stream that can reach into small spaces or crevices in your lawn more easily than other methods. They’re also helpful on weeds growing against fences, walls, or pavements as they have strong enough pressure to penetrate these surfaces – but don’t use them around delicate plants like flowers. These are perfect if you want something with high coverage rates. 

The downside? It’s not always easy to find an Aqua Jet nozzle because they come in so many variations – some may actually be called “high volume” nozzles.

Key Features:


The pressure that’s applied to the nozzle will determine how quickly and evenly your weeds are killed. It is important to consider this before purchasing a product because not all models offer an adjustable option. If you’re using it on delicate plants or fragile ground, you’ll want a more gentle stream so as not to cause unnecessary damage. Higher pressures produce faster results but may be too strong for softer foliage if there isn’t enough water mixed in with the solution. Such low-pressure products might include those made by Chapin, Wagner, Grillo-Werk, and Solo

Container types

Containers will vary as well. Some products come with a built-in container while others require an external reservoir or garden hose attachment that may not work depending on the size of your weeds. Backpack sprayers offer stability, freedom from back strain, and added mobility but these typically hold less fluid than their smaller counterparts do, so refill time should also be taken into consideration.


Sprayers that are more durable will last for years. The models highlighted in this article are made of high-quality materials and have a much higher lifespan. Manufacturers recognize the need to provide long use with minimal maintenance, which is why you can expect these sprayers to serve their purpose well over time.

The durability of the product can vary depending on how you use it and where it’s being used. Consult the manufacturer’s manual about what to expect when using this specific model in different ways or in various environments before making any assumptions about its longevity or quality construction material. If properly cared for, these products will last years without breaking down due to general wear and tear from frequent uses.

Tank capacity

Many weed killers are designed to kill weeds by spraying the chemical over a large area. The tank capacity of your sprayer will be an important consideration when considering which is best for you, as it will determine how much product can be used at any given time. For example, if you have many acres that need to be sprayed with weed killer, a larger-capacity sprayer may suit your needs better than a smaller one.

Tank capacity is the amount of liquid that a sprayer can hold. This affects how much fuel you’ll need for your machine and also how often you will have to stop to refill. 

Some machines, like those with manual pumps, may only be able to handle small weed killer amounts. Whereas others with pressurized tanks can carry up to 64 ounces without difficulty and won’t require refilling as often.  

Large tanks are great if you have a lot of large areas to cover, but not so good if you only need to go after weeds in small patches. The average garden needs at least 500 liters and most homeowners would benefit from being able to connect multiple tanks together with an outlet valve that allows them to pump water between two containers without having one tank empty before moving on to the next area. 

In order for this system to work effectively it’s important that both tanks be identical as they will now serve as part of a closed-loop rather than functioning independently.


How often should you spray weed killer?

The frequency of application varies depending on the weeds, type of weed killer is used, and environment where it’s applied. A general guideline for two applications per year should be sufficient for most homeowners who apply a granular herbicide around their lawns or planter beds where they are growing plants that don’t tolerate glyphosate directly (like vegetables). 

If you’re spraying an organic herbicide composed primarily of citrus oil then you may want to spray twice as often since these types can break down more quickly than others when exposed to sunlight over time.

What is the best sprayer for Roundup?

The Roundup Ready Spray Bottle Sprayer is the best sprayer for Roundup. The product delivers a fine mist of liquid that clings to leaves and works well on hard-to-reach areas like underneath bushes or in corners. It also has a five-star rating from Amazon customers who say it’s easy to use with no leaks. 

To use the sprayer, remove the top and then fill it with Roundup. Attach a hose to your garden hose or faucet and turn on the water. Lift up the lever for spraying by squeezing down on both sides of the handle. To adjust pressure, release one side and press up if you want more force or lower if you want less power in your stream. 

For an even finer mist, place nozzle between two fingers before spraying onto leaves that cover ground such as ivy patches or other weeds close to sidewalks/driveways. The manufacturer recommends using this product within 12 months after purchase due to its effectiveness diminishing over time degradation from sunlight exposure.

Can you use the same sprayer for fertilizer and weed killer?

The best sprayer for weed killer is also a great option for fertilizer. Ideally, you should have two different sprayers to avoid mixing them up and wasting product or having a reaction between the two substances that can make either of their effects less effective.  

What sprayer sprays the farthest?

It all depends on the pressure of the sprayer. If it is a handheld with low to medium pressure then you will be limited in how far away from your target area that you can reach. If you want to cover as much ground or have a larger target space, go for one with higher pressures and more vertical range (if applicable). The wider nozzle also helps distribute coverage evenly versus just spraying straight out. 

The best way to find the right sprayer for your weed killer needs is by figuring out which of these two factors you want more. If you’re looking for a simple and affordable option, go with something low-pressure that can be used in tight spaces like patios, walkways, or close to buildings. For large areas where the coverage is a key (or if you just have deep pockets), then get something higher pressure so it’s not limited by range and has enough power behind each stream to cover as much ground as possible before needing refilling.

Can you spray fungicide and weed killer together?

Yes. Fungicides and weed killers are different types of chemicals that differ in their active ingredients, which means the two can be mixed together without any problems. In fact, it is often recommended to mix fungicide with a weed killer for better effectiveness.

Can you wash the RoundUp out of a sprayer?

Sprayers are made from porous materials that can retain some residues, and it may not be possible to remove all traces of residue or break down the active ingredient with water alone. But still you can try – try using soapy water for washing away any remaining chemicals after use as well as thorough rinsing before reuse.

How do you clean weed killer sprayer?

Every time you use your sprayer, it should be cleaned. Weed killers can clog or damage the nozzle if not removed from the machine properly. Signs that you need to clean out weed killer include spraying a small amount of water and getting back thick weeds instead of an even mist; noticing any leakage in the tank which may cause overspray onto clothes or areas around equipment; or if there is the buildup on parts such as seals, nozzles, filters, etc.

To clean an electric weed sprayer, use a garden hose to rinse out the tank and then fill it with fresh water for spraying weeds. If you have a car wash surface cleaner or hand-operated machine: don’t forget to remove any attachments from the gun before cleaning! 

Fill each cup of your cleanser in a placeholder with water and add one drop per every 16 ounces of the solution so that there is still enough chemical left in case there are stubborn clogs or extreme build-up on parts. Place the nozzle cap back onto the end of the wand when done. When using this method make sure not to restrict flow by over-tightening caps as frequently as they can be tightened too much which causes clogs!

For a hand-operated sprayer, like the backpack or handheld versions: ̶fill your bucket with water and add two tablespoons of dish soap to each gallon. Soak items for about fifteen minutes then rinse them off completely. If you have stubborn residue that is not rinsing out after soaking twice, try using an old toothbrush (or other brush) to scrub it away.

You can use many common household products such as vinegar, alcohol-based window cleaner, vegetable oil cooking spray, or even hot sauce in place of commercial cleaning agents but make sure you follow all directions on the bottle before use.

How far will a pump up sprayer spray?

A pump-up sprayer will typically cover a range of about 25 feet, and may be able to go as far as 50 feet. The distance it covers depends on the pressure that you are pumping at, which is determined by how fast you pull the cord. You can also add an extension hose for more length if needed.

How far will a hand pump sprayer spray?

For the best results, it is suggested that you keep your target at least 12 inches away from where you are spraying. This will allow for full dispersion of the weed killer without any overspray and also make it more convenient to get all areas while preventing hand fatigue. 

Hand pumps can be a good option if you want something lightweight or inexpensive as well as easy to clean up afterward. The downside with these sprayers is they take longer than other types of sprays like backpack units that means you might have to plan ahead when using them on larger jobs in order not to waste time having to stop every few minutes just because your arm needs a rest!

Can you put bleach in a sprayer?

Bleach is not recommended for use in a sprayer. It will corrode the metal and make it unsafe to spray over food plants or other living things. If you have an area that needs bleach, try using a hand-held nozzle bottle instead of your pesticide applicator for those specific areas only.
