If you don't want to apply liquid, but rather dry pesticides such as algae lime or rock flour, this only works with a so-called powder atomizer. The device distributes the dust finely and evenly to the designated areas. We will introduce you to powder atomizers that are suitable for home and hobby gardens and also explain which criteria you should pay particular attention to when buying.
With a powder atomizer, powder can also be applied very easily

Purchase Criteria
purpose of use
In contrast to conventional pressure sprayers, which are designed for dispensing liquids, powder atomizers are suitable for dry and fine flours. You blow it flat and finely distributed on surfaces such as plants. Please note that powder atomizers are not suitable for applying granules and can usually only be used for biological agents such as rock flour, algae lime, lava flour and the like. For granules, on the other hand, there are special granulate spreaders.
device type
Powder atomizers are available in two different versions. The handy, small hand-held atomizers are operated manually using bellows and usually only hold up to approx. 500 grams of powder material. They are good for pollinating individual plants or small areas. If, on the other hand, it is about the long and high boxwood hedge in the garden, the purchase of a pressure sprayer especially for powder is advisable. This works in a similar way to a pump sprayer for liquid and holds up to five liters of powder, which corresponds to around five kilograms.
materials and weight
Powder atomizers are usually made of robust plastic and are also very light, since they usually do not have a large filling capacity. With plastic products, remember that you must not expose them to weather conditions such as sun, frost, heat or moisture for a long period of time, otherwise the material will become porous and the device will no longer be able to fulfill its intended function.
atomizing nozzles
Special atomizer nozzles are required so that the powder can be evenly atomized and distributed from the container. Powder atomizers that come with different, interchangeable attachment nozzles are practical, so you can create different spray mists - finer or coarser, depending on your needs. In addition, the nozzles must be easy to clean after use to prevent clogging. With some hand-held sprayers, there is also the option of purchasing an extension separately, which you can then use to dust hard-to-reach areas.
filling capacity
Most handheld powder atomizers have a capacity of up to 500 grams, which is usually perfectly adequate for home and hobby use. It is only worth purchasing a special pressure sprayer with a larger capacity if you have a higher demand - for example because you have to regularly whitewash a very large lawn, an old and long boxwood hedge and/or a large chicken coop.
operating pressure
The operating pressure, which is given in bar, is only relevant when purchasing a pressure sprayer. Since hand-held atomizers are operated by means of bellows, the build-up of pressure is irrelevant to them. Pressure sprayers usually build up a pressure of up to three bar, which is completely sufficient for the intended applications. It makes sense to purchase a device with a safety valve so that excess pressure can be released if necessary.
youtubefrequently asked Questions
What is a powder atomizer?
Powder atomizers are special pumping devices that are intended for the flat and fine application of powdery and dry materials. As a rule, these are handy, small devices that are operated by means of bellows. However, there are also larger models that work like a pressure sprayer.
Which materials can be applied with a powder atomizer?
With powder atomizers you apply dry and powdery agents, for example for plant protection. These are usually biological agents such as algae or sea lime, rock and bedrock flour, lava flour, diatomaceous earth (silica) and the like. It is important that the materials to be atomized are fine-grained and absolutely dry. Granules cannot be distributed with a powder atomizer, nor can liquids or moist powders.
Why do you need a powder atomizer?
Powder atomizers are used wherever you need to apply fine powder. This is often the case in plant protection, for example if you want to dust the boxwood with algae lime or rock dust to prevent the boxwood moth. But these devices are also very practical for liming the lawn or for dusting the chicken coop to combat mites.
Can't I just use a normal compressed air sprayer for these purposes?
No, that doesn't work. Conventional pressure sprayers are not designed for powdery, dry materials, but for liquids (which also must not be acidic or greasy!). If you still want a pressure sprayer, choose a model that is suitable for atomizing powders. Improper use means that the corresponding device quickly breaks down.
Which manufacturers produce high-quality powder atomizers?
The market leader in the powder atomizer segment is undoubtedly the manufacturer Birchmeier, which offers a large selection of other sprayers and is based in Switzerland. The German manufacturer Gloria is also one of the big names in this segment. The producers Cuxin and Hügelsberger also supply high-quality goods, with the latter specializing in pest control.
