This versatile sprayer is great for both personal lawn care and commercial operations. The comfortable grip keeps you in control as you pump harsh chemicals or clean completed areas. The commercial-grade shutoff is great for emergency stops, and the inline filter is very easy to clean after heavy usage.
The 21-inch poly wand is augmented by Viton gaskets that resist damage from prolonged chemical exposure. There is a convenient nozzle holster that allows you to store the wand with ease. This is one pump that won't need to be replaced every other year. When you need to change fluids, the pressure release safety valve prevents harmful chemicals from getting on your clothes or skin.
Adjusting each nozzle is also a cinch. With just a mere twist, you can choose from four separate spray options. The fine mist cone is the default setting, and it makes covering large areas quick and simple. The low-volume fan nozzle helps you with precision targeting of specific areas. The high-volume fan nozzle is there when you need broader coverage. Finally, the foaming nozzle is great when you want to see where you have already sprayed.

2. Smith Performance Sprayers R200 2-Gallon Compression Sprayer
This professional-grade sprayer is great for tackling multiple jobs each day.

There is one quirk that you should be aware of before purchasing this unit. When the wand is placed in the storage tray, small amounts of liquid can be discharged into the tray.

How to Choose the Best Weed Sprayer
These are just a few guidelines for choosing the best sprayer for the job. When researching each model, pay attention to how many of these considerations are met.
Pumps that let you make slight adjustments to the pressure during output are the most efficient. Every job has a perfect flow rate and being able to adjust the psi on the fly is the best way to find the sweet spot. Look for dials that let you choose the psi just by rotating them. This will save you tons of materials in the long run, and it will improve battery life on electric models.
Learn about noise levels
Like any power tool, weed sprayers are liable to make tons of noise. It doesn't matter how loud a pump is at an industrial site, but the noise level is very important during personal lawn care. You don't want to upset your neighbors or have the police called if you produce enough of a racket. Consider a permanent magnet motor for home environments. They are nearly inaudible at lower rpm settings.
Each weed sprayer is built with a unique purpose in mind. Sprayers meant for home use offer lower output volume at a much cheaper price. Professional-grade equipment is more expensive but optimized to cover larger areas much faster. When choosing a weed sprayer, think ahead about all of the locations you intend to use it. If you see yourself only tending to your personal lawn, you can save some money by opting for a smaller unit. If you plan to do large scale jobs and a few things around the house, then you will want to get a more versatile unit.
Each nozzle is best for different types of tasks. Some shoot in cone patterns and others shower whatever you are spraying with everything you have. It stands to reason that the more types of nozzles a sprayer supports, the more functionality you will get to enjoy. Look for pumps that come with four or more starter nozzles. If the sprayer supports additional add-on nozzles, then that's a sweet bonus as well.
The equipped nozzle is only as good as the machine it is attached to. Most sprayers use a hose-like wand to control where the fluid goes. These wands use either wet or dry booms to get the output flowing. Dry booms carry liquid through a tube attached to the beam. Wet booms use pipes inside the beam to transport the fluid. They are pretty similar, although dry booms tend to last a bit longer before wearing down.
Best Weed Sprayer Buyer's Guide
Here are answers to some of the most common questions regarding weed sprayers.
Do I need different nozzles for different chemical types?
Yes, there are four main types of chemicals that may require different nozzles based on their proper droplet size and chemical pressure. Herbicides and fertilizers work best with nozzles that output low pressure with high droplet size. Fungicides and insecticides generally require higher pressure and smaller droplet size to be most effective. When in doubt, check the chart of proper droplet sizes on the chemical you are using.
Can I use the same nozzles on both my pull-type and self-propelled sprayer?
Yes, as long as you mind the difference in speed. A self-propelled motor will go twice as fast as a pull-type. If you have a ten-gallon pull nozzle, you could use a five-gallon self-propelled tip to bridge the gap.
How do I know the flow meter is accurate?
There is a tag on every flow meter known as the flow calibration number. You must make sure that the number matches the calibration number located on the rate controller. If they line up, you can begin the re-calibration process to get everything back in sync.
How can I manage weed resistance buildup?
Diseases and weeds will naturally build up resistance to agricultural chemicals if you repeatedly use the same products over and over. Your best bet is to constantly cycle out different products in a rotation that keeps the weeds guessing. You can stay ahead of fungicide resistance by using alternate activity groups. To prevent resistance to herbicides, cycle through all the modes of action you have access to.
What to do if my control valve stops working?
Many modern sprayers allow you to toggle between manual and auto mode. If your sprayer is switched to auto, you won't be able to adjust the flow rate. Switch it back to manual mode in order to test out your flow control. If problems still persist, please contact the manufacturer's customer service representatives.
Can I spray during extreme heat or drought conditions?
A majority of the products on the market work in conjunction with the weed's natural growing conditions. If a weed is under heat stress, it may not respond to the chemical reaction. Check the label on each chemical you plan to use to see if they still work in extreme temperatures.
How does a rate controller work?
A rate controller uses variables such as the programmed rate, speed, and boom width to adjust the level of the flow meter. Once the connection is made, the control valve is opened or closed in order to sync up both meters.
We looked at several different weed sprayers that have been dominating the market. While all of these models are quite spectacular, there can be only one that earns the title of best pump sprayer for weeds.
