Uses Of Commercial Backpack Sprayers
Selecting the best backpack sprayer is necessary so you can maximize its uses. Backpack sprayers are usually used for Roundup, weed killer, and pest control, but it can also be used for bleach to treat mildew, as well as for spraying compost tea to keep your plants healthy. Just make sure to determine where you will be using your backpack sprayer first before buying one to prevent crop damage as a result of contamination.
Backpack sprayers are primarily being used for herbicides and pesticides
Types Of Commercial Backpack Sprayers
Backpack sprayers have two types of pumps: a piston pump and a diaphragm pump. A piston pump sprayer produces a higher pressure which is around 90 psi as compared to a diaphragm pump that produces 40 psi. Higher pressure creates finer water droplets, allowing you to spread the liquid evenly over a wider area. If you want to be sure about how much pressure you are using each time you spray, consider getting a pressure gauge. Brands like Solo manufacture pressure gauge that can be fitted to your Solo backpack sprayer.
A piston pump works in an up and down motion and is enclosed in a chamber inside the tank. Pumping the lever creates pressure that forces the liquid into the wand and then sprayed out. Piston pump sprayers cannot be used for highly abrasive chemicals because the chemicals will damage the piston.
Piston backpack sprayers can produce more pressure to help reach taller plants, especially for trees
On the other hand, a diaphragm pump is proven to be more durable than the piston pump. Furthermore, it does not have an internal cylinder. Pumping the handle of the pump moves the diaphragm to generate the pressure. Diaphragm pumps are designed to be used with various formulations of herbicides since the diaphragm does not get into contact with any of the liquid inside the tank. This type of pump was specifically developed to handle abrasive chemicals as well as chemical residue.
Make sure to protect yourself when using backpack sprayer with pesticide
Backpack sprayers come in different tank volumes. It is important to choose the right tank depending on the size of the area to be covered, as well as the weight that you can carry on your back. You don’t have to purchase a large tank if the area to be covered is not that wide. You should not buy the smallest as well since it will require more refills.
Make sure to choose the right tank capacity that fits your needs
Backpack sprayer tanks usually come in 2-gallon, 3-gallon, or 4-gallon capacity. Most backpack sprayers have a 4-gallon tank.
Backpack sprayers have three different types:
- Manual Pump Sprayers
- Battery Operated (electric) Sprayers
- Gas Sprayers
How To Select The Best Backpack Sprayer For Your Needs
There are several types of backpack sprayers, so knowing the specific type that will suit your needs is very important. You should also consider the durability of the equipment and the availability of its parts if the need for repairs arises.
One thing to take note is the coverage of the area to be treated. For large scale farming, it is ideal to use motorized ATV sprayers. For consistent use in smaller gardens, pump sprayers are more advisable to avoid fatigue from overwork when using a backpack sprayer. If you dislike having to manually pump your sprayer, you can opt for a battery-powered backpack sprayer. This way, all you have to do is flip a switch and swing the wand over the area you wish to cover. Plus, the tank is usually made out of high-density polyethylene plastic that’s durable yet lightweight; you are less likely to get sore muscles after a long day in the garden. Some manufacturers make translucent tanks, such as in a Harbor Freight backpack sprayer, so you can see the amount of liquid left inside.
Most battery-operated sprayers, like a Solo Backpack Sprayer, can operate up to 8 hours before you need to charge it again. No other type of backpack sprayer offers such convenience. However, it is important to note that motorized pumps are usually more expensive and require more maintenance, so you might need to consider this before heading out to buy a battery backpack sprayer.
Motorized sprayers are recommended for large-scale farming use
Choosing the right spray wand is also important. It should be less susceptible to leaks and provide an accurate spray application. Most backpack sprayers nowadays come with an adjustable nozzle that lets you control the spray pattern. Selecting a wand that is compatible with TeeJet nozzles lets the user switch out and use different nozzle types needed to match different applications.
Steel wands are proven to be more durable for backpack spraying use
Lastly, if you want to use your backpack sprayer for applying oil-based carriers for controlling woody plants, make sure that the sprayer is equipped with oil-based carrier resistant parts. This is important to protect your sprayer from being damaged over time.
Commercial Backpack Sprayer Maintenance Tips
Once you have selected the best backpack sprayer for you, make sure to take care of it. You can keep your backpack sprayer in top shape with a couple of maintenance tips.
- The most important thing to remember is to thoroughly clean your sprayer after every use, especially if you are using it both as a chemical sprayer and non-chemical mist blower. Drain any excess liquid after each use and make sure to rinse your equipment with clean water or tank cleaner to ensure that no chemical residue remains in it. The shut-off valve may also trap harsh chemicals in it, so it’s necessary to rinse this part well to avoid contamination. Keeping your backpack sprayer clean will help prolong its life and reduce the number of maintenance repairs.
Keeping your backpack sprayer clean every after use helps prolong its life
- Observe safety precautions when handling herbicides that are left inside the tanks of your backpack weed sprayer. Make sure to read the label of the herbicide for proper handling and disposal.
- If you live in an area with a colder climate, winterizing your equipment is essential before storing. To winterize your backpack sprayer, apply antifreeze solution to the tank to prevent it from freezing.
- Follow the manufacturer’s guide in lubricating your equipment. Lubricate all the seals and O-rings as recommended at the start of every spray season. Lubricate them as needed if the unit is heavily used.
Calibrating Commercial Backpack Sprayers
If you intend to use your backpack sprayer to apply a fixed broadcast rate per acre, it is necessary to calibrate your equipment. Calibrating is determining the spray volume you need to have over a specific area. It helps in calculating how much product is needed to be added to the tank based on the manufacturer’s instructions. Calibrating your backpack sprayer is important to prevent serious problems such as dead crops and ineffective pest control.
Proper calibration will help you determine the amount of pesticide or herbicide to be used
Calibrating your backpack sprayer is simple, but first, remember that one gallon=128 fluid ounces. This means that the calibration spray area should be 1/128 of an acre. This will help you make sure that the fluid ounces that would be collected during calibration will be calculated as gallons per acre.
- The first step of calibration is making sure that your sprayer and nozzle are clean. Fill the tank with water then spray some water on any surface to test if the nozzle is working properly. Choose the right nozzle that produces a uniform pattern for the area to be treated.
- Next, measure 18.5 by 18.5 feet on an area on the field where the spray will be applied. Measure the time it takes to cover that area uniformly by spraying with your wand gently from side to side. Do this step twice and get the average time.
- Then, with a constant spray pressure, spray into a container for the time you just calculated. Measure the number of fluid ounces collected in the container. This will be the number of fluid ounces that is equal to the number of gallons per acre that the sprayer will deliver. For a sample computation, if you have collected 5 fluid ounces of water in the container, then the sprayer will apply an herbicide solution at a rate of 5 gallons per acre.
These are the basic steps in calibrating your backpack sprayer. Simply follow these steps to make sure that your backpack sprayer will apply consistent spraying for your herbicide to be more effective.
