Neem Oil and Potassium Soap: What are they and how are they used

More and more people are reluctant to use chemical components to combat pests and plant diseases. These products are not only harmful to insects and fungi, but also to fauna and even flora found in the environment. In the case of vegetables, it can even be harmful to ourselves. However, it is important to know and know how to apply the ecological options that we have. That’s why we’re going to talk on Neem oil and potassium soap.

If you do not know what these natural products are, I recommend that you continue reading. We will explain what they are for, the doses that we must apply and how they are used.

What is Neem oil?

Neem oil is extracted from the fruits of the Neem tree.

Before talking about how to use Neem oil and potassium soap, we must first clarify what both products are, starting with the first. Also known as Neem extract, This oil is a natural insecticide widely used in gardening and organic farming. It is extracted from the fruits of the tree called Please (hence the name of the product). It helps fight various pests and fungi, but it is also a good preventive product.

The application of Neem oil is carried out through irrigation or by spraying. It is important to note that this product should not be applied together with sulfur. The mixture of both products produces a phytotoxic reaction, that is: It poisons the plants. If we want to use both sulfur and Neem oil, it is essential that we leave at least three weeks between each application so as not to damage the vegetables. The same thing happens with copper, but in this case we can leave a period of two weeks between applications.

But what pests does Neem oil act against? Well, let’s see, some are the minelayer, the White flyplatforms, aphid, trips, cochineal, the fleas, the Mites, bed bugs, small caterpillars, small locusts or grasshoppers, weevils and termites. Definitely: It is used to combat practically all soft insects, including its larvae, but it is also very effective against some fungi such as rust, mildew and powdery mildew. In the event that we have problems with some more powerful fungi, such as black spot, alternaria or botrytis, a good option is to add sodium bicarbonate. This will make the mixture more effective.

  • Prevention: Neem oil application every 15 to 20 days.
  • Treat pests: Application every 4 to 5 days until the pest has been completely eliminated. In the event that the plague is very serious, only Neem oil can be applied by irrigation, without bicarbonate.
  • Fight pests with foliar treatment: Every 4 to 5 days.

This product is perfectly capable of completely eliminating some pests, such as trips, aphids, mealybugs or the Red spider. To achieve this we must apply it every 3 to 5 days.
