Natural pesticide, pyrethrum
There are a large number of synthetic broad-spectrum insecticides available on the market. The only drawback is that these insecticides are harmful to human health and the environment. To take care of the vegetable garden, especially when you want to eliminate parasites or insects that are generally not so harmful, it is best to use natural remedies.
Among the ready-to-use natural remedies we point out pyrethrum, which is also useful in case of extensive infestations.
The pyrethrum, before being a natural insecticide, it's a plant! Its active ingredient, pyrethrin, is very effective in counteracting most of the vegetable and garden pests,plant liceincluded. This natural remedy is effective against:
2. crop bugs and green bed bugs
4. myrides as the vector of the potato mosaic virus
6. white fly
7. aphids and other plant lice
9. common fly and mosquitoes
10. many other plant parasitic insects
There are several pyrethrum-based insecticides on the market, they can be purchased in the form of powder, spray or concentrated liquid solution, to be diluted with water before use.
L'natural insecticide pyrethrum-based can be purchased at specialized garden centers or can be purchased online: a package of Solabiol Piretro Actigreen Bio is offered on Amazon at a price of € 19.90 with free shipping. For all the info, I refer you to the official Amazon product page: Actigreen Bio Liquid solution.
Unfortunately, many people are convinced that pyrethrum is not effective. In reality they are only wrong to use it !!
Pyrethrin is a photosensitive substance (it deactivates in direct sunlight), therefore, especially in liquid form, pyrethrum-based insecticides should be used in the late afternoon, when the sun no longer beats. In shady areas, it can be used at any time of the day. Only in this way can this pesticide manifest its effects and eliminate your parasites in a natural way.
Preparation is simple. Fresh or dried nettles are left to macerate in 10 liters of water. You need 500 grams of dried nettle or 1 kg of fresh nettle. Remove the roots of the nettles and place them in boiling water.
Let the nettles soak for 4 days, filter and use the residual liquid for the treatment against aphids or to fertigate the plants. The liquid must be sprayed over the entire plant.
