If you are thinking of spraying Roundup in your garden to kill weeds, you first need to choose the best sprayer to use.
Since Roundup is non-selective, you have to apply it to unwanted plants only. Besides, you must mix it with water in recommended ratios for the best results.
Ideally, you can use the traditional sprayer to apply Roundup. But most of them have limitations, especially when it comes to size and ease of use.
Unfortunately, that is not as easy as it seems because the market has a wide range of sprayers to choose from. Furthermore, if you forego using a pump sprayer that works best for Roundup, you can end up spraying unevenly.
Therefore, that raises the question – which sprayer do you need?
Top 3 sprayers to use with Roundup in 2022
- Best Overall: CHAPIN 20003 Gallon Lawn Sprayer
- Best Value for money: Roundup Pump’ N Go 2.1 Sprayer
- Best Quality: MY4SONS M4 Battery-Powered Backpack Sprayer
What to consider when looking for a sprayer to use with Roundup
Since the market has many different sprayers that you can use with Roundup, determining the best can be challenging.
However, here are some things to consider when making your choice.
Although you want a sprayer to use with Roundup, getting one that offers multiple applications is also helpful.
2. Adjustable nozzle
The best pump sprayer for weeds should have an adjustable nozzle since makes it easier for you to regulate the spray volume.
Furthermore, it helps you to obtain uniform spray coverage, especially in large areas.
3. Backpack vs handheld
You can either buy a backpack or handheld sprayer for Roundup. Both sprayers achieve the same function.
However, the backpack is more convenient than the handheld sprayer because it is easy to carry and can complete tasks without interruption. But it is expensive and limited in size.
The handheld sprayer is available in any size, is easy to use, and is inexpensive. However, it can be heavy and may cause accidental chemical spills.
4. Locking trigger mechanism
A locking trigger mechanism is helpful in a sprayer for Roundup. It ensures that you lock the sprayer to avoid chemical spillage.
In addition, the mechanism comes in handy when you want to avoid spraying Roundup on suitable plants.
5. In-tank filter
An in-tank filter helps keep debris from entering the pump. As a result, it will not block the pump from delivering the chemical to the targeted area.
Furthermore, you will continue spraying even if the tank has too much debris.

Should you put Roundup in a pump sprayer?
You can put Roundup in a pump sprayer and use it to kill weeds in your garden.
But when doing so, you must ensure to depressurize the pump sprayer by pushing the handle down and turning it anticlockwise until you release all the pressure. Once depressurized, pour the Roundup chemical into the pump sprayer.
Add Roundup into a pump sprayer slowly to prevent foaming. Do not overfill it.
Can I use the same sprayer for Roundup and fertilizer?
You can use the same sprayer for Roundup and fertilizer. However, it would be best to first clean the sprayer before you add the fertilizer.
Ideally, you can clean the sprayer using running water. You can also use a solution containing water and bleach, ammonia solution, powdered detergent, or kerosene.
It would also be helpful to use de-greasing liquid dish soap.
What is the best way to clean Roundup out of a sprayer
You can clean Roundup out of a sprayer through these steps:
- Empty the sprayer by disposing of any liquid remaining in the container
- Prepare some hot water
- Pour the hot water into the sprayer
- Flush the sprayer with hot water then empty it
- Add an ammonia-based cleaning solution to the sprayer
- Add at least one ounce of ammonia to 3.8 liters of water. The solution shouldn’t exceed the halfway mark on your sprayer.
- Allow the solution to rest overnight.
- Spray the solution the following day.
- Flush the sprayer again using hot water.
- Deep clean other parts of the sprayer.
Although you can neutralize Roundup using water alone, ensure you clean the container thoroughly before using fertilizer.
Also, it is helpful to repeat the procedure at least twice to ensure you remove any residual chemicals.

However, the three best sprayers to consider are Roundup Pump’ N Go 2.1, CHAPIN 20003, and M4 MY4SONS.
