DIY organic insecticide

This do-it-yourself pesticide, excellent for garden care, is produced easily and with minimal economic investment. The ingredients provided for the recipe are only two but depending on who proposes it they vary in proportion. According to the guidelines of theGardening Australia, the typical proportion to use is 4 parts of vegetable oil (enotmineral oil) and a part of dish soap.

This organic pesticide must be used pure for the treatment of an ongoing infestation while it can be used diluted (dilution 1:50) with water in case of preventive treatment. How to prepare thishomemade insecticide? Here's what you need:

  • 400 ml of vegetable oil
    seed oil, corn oil, soybean oil, canola oil ...
  • 100 ml of dish soap
    the liquid detergent will increase the time the oil remains on the plant.

Take 400ml of vegetable oil of your choice * and add it to 100ml of detergent or liquid soap **. Shake trying to homogenize the mixture. Transfer the mixture to a shoulder applicator or spray bottle. During application it is recommended to shake the spray bottle more often or mix the mixture with a wooden stick.

Ready-to-use organic insecticide

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, 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 countering most of the garden and vegetable pestsplant liceincluded. This natural remedy is effective against:

1. scissors
2. crop bugs and green bugs
3. beetles
4. myrides as the vector of the potato mosaic virus
5. leafhoppers
6. white fly
7. aphids and other plant lice
8. altica
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.

* Tips for choosing vegetable oil
Many recommend rapeseed or canola oil because it is odorless and therefore also applicable to house plants or garden plants close to the house.

**Tips for choosing the detergent
For a more natural action, replace the dish soap with pure castile soap which proves to be just as good, the only drawback is that it is a little more expensive than dish soap or it will have to be purchased solid and then transformed in a liquid state by applying heat or by dissolving it in a pinch of water.
