For some, the first days of July bring the long-awaited signal to start getting ready for the annual vacation, while others are heralding the fight against ragweed pollen. This annual weed produces pollen from early July until the first frost. One stalk of ragweed produces millions of pollen grains and tens of thousands of seeds, which cause a lot of problems for humans.
Almost all of us know at least one person who is allergic to ragweed. People who strongly react to ragweed pollen often complain of a compromised quality of life caused by the allergy in the summer months. Thanks to Professor Miloš Stanković, PhD, a scientist and inventor, they could soon forget about their troubles and start breathing without hindrance. He invented the Ambrozer, a device that uses radio frequency and electricity to recognize and destroy this plant at the root.
“My brother has had a problem with ragweed since he was a small child, as have many people from my environment. I wanted to help them, so I started developing the device. Even the famous Nikola Tesla was trying to make an electric device that would destroy weed. Since then, many people have produced various devices, but they needed to meet numerous safety requirements in the EU and the rest of the world. I succeeded in that”, explains Dr Stanković, who is an electrical engineer by profession.

The device that destroys ragweed consists of electronic components and electrodes. With the help of a certain frequency and current, the weed is destroyed at the root without the use of chemical compounds and pesticides. In this environmentally friendly way, the weed not only disappears but no longer grows at all during the season.
“By regulating the frequency, weed or a specific part of the plant is destroyed. The frequency used to eliminate weed is adjusted to the specific weed type. During the physical contact between the electrodes (on the device) and the weed that is being treated, biochemical and biophysical processes occurring in the weed, due to which it instantly withers. The device should be used while the weed is small, due to less electricity consumption”, explains Dr Stanković.
The device can be set to destroy a group of weeds or to be more selective. According to the inventor, ragweed is the easiest to destroy. As everything is treated physically and selectively, there is no impact on other agricultural crops, useful plants and microorganisms.
