Inventions also serve daily life. Such as oil tank protection device, automatic air purifier, environmental protection car buzzer, silent lawn mower, inflatable umbrella and so on. Among them, he invented non-toxic pesticides because he saw his wife Lotus.
One day, his wife sprayed insect-infested oleander with pesticides on the balcony. He thought, it should be possible to kill insects without poison spray. "Then, he began to think along this line of thought. A few days later, he had an idea: "there is a part of the human body that is not disturbed by lice, bedbugs and other insects, and that is the ear." "
On the same day, Hashabi asked someone to analyze the composition of earwax in the laboratory. Earwax consists of 120 different substances, one of which can drive away or even kill insects. In the same year, he successfully developed a non-toxic pesticide obtained from this substance. It was recommended and introduced at the International Plant Expo held in Essen. I hope this helps.
