They are suitable for all weed-killing products, including pesticides, herbicides, insecticides, fungicides, fertilizers used for garden and lawn treatment. The prices vary from £15 for small 5L spray bottles up to £40 for high-capacity 20L backpack sprayers.

There are also higher-capacity (up to 98L) weed sprayers powered by a 12V battery or connected via a 12V supply on the vehicle.

Sealey 37L automatic weed sprayer may become a key garden tool removing the need for almost all hand-pumped stuff. It produces about 3.7 liters a minute. The tank is manufactured using chemical-resistant material and is suitable for use with different agents: weed killer, de-icer, and spraying fertilizer. It is powered by a 12V battery or connected via a 12V supply on the vehicle. Draper 98 Litre ATV Spot/Broadcast Sprayer can be mounted to any all-terrain vehicle/mower.

Testing & Customers Reviews

Here are the reviews from YouTube bloggers who tested the weed sprayer and have found them effective and worth buying.

Knotweed Removal: "Here we have the Spear and Jackson pressure sprayer. Great for chemical spraying within the garden, very reliable well built.

It has a locking facility on the handle as well, so, once you've pumped it, you can just put that down. Carrying handle, obviously, to put it over your shoulder. A long nozzle to reach into the plant and more importantly it has a locking facility on the handle as well. So, you don't get any fatigue using it alongside the the gallup lysophate herbs, like weed killer.

It makes an ideal way of doing your weed treatment in the garden."

Russell Platten: "This is Oregon 518771 backpack sprayer. It comes in a 16 liter and 20 liter size. I've spent a little bit more money on an Oregon sprayer, is because I've got two other sprays, out there made by reputable companies, that are just basically falling apart.

I've really enjoyed using Oregon. It's a very very effective sprayer works very well. But, you need to make sure that you taken everything up before you use it, because I've got absolutely covered in weed killers, which is not a good thing.

It is very heavy when you've been carrying it for a while. 20 kilograms plus the weight of the backpack means that you need to be fairly strong to use it for any length of time. Obviously, the more you use it probably the more you still get to it. But it does feel like it's reasonably professional, it does a very good job of spraying. And for the money, I think it's good value anyway."
