Pests run as soon as they smell it, and Israel launches herbal essence insect repellents to kill all kinds of pesticides.

Although chemical pesticides can kill pests, they can also cause three side effects: first, they may cause pesticide residues and endanger human health; second, they will kill beneficial insects, such as bees; and third, pests develop drug resistance, thus making the pest more serious.

So, is there an insecticide that kills pests without damaging the environment?

Scientists from all over the world are studying it, but many research results are not satisfactory. For example, some biological insecticides, although effective, but the effect is slow. Before the bug father was killed, the bug son already knew how to buy soy sauce. The vegetable farmer can't afford to get hurt.

Recently, an Israeli startup has developed a new type of insecticide using herbs. It allows farmers to protect their crops while avoiding the use of pesticides that damage the environment.

In their research, scientists have found that some plants in nature are never attacked by insects. It turns out that these plants secrete liquids or gases that keep pests away. For example, red spider, leaf miner, thrips, whitefly and so on. These things are uninvited guests that farmers hate.

So the extraction of these secretions, used in agriculture, can not effectively prevent insects?

So the company extracted this secretion from desert plants and made herbal extracts.

This herbal pesticide is used in a greenhouse in Italy. A sprinkler is installed at the entrance of the greenhouse, and the insecticide is sprayed on the entrance and the greenhouse net regularly every day. You don't have to spray it directly on the plants. It turns out that the pest control rate is almost 100%, reducing the use of pesticides by more than 80%, while the pest invasion rate in the control greenhouse is more than 500%.

This insecticide is harmless and is used throughout the planting cycle, especially during the important period before harvest.
