Neem oil is a natural insecticide, widely used in organic farming, as it helps fight pests such as aphids and spider mites. It acts as a repellent, preventing insects from damaging plants. Also, if your plants are already affected, neem oil will help you to kill the bugs.

Neem oil is obtained from the seeds of Azadirachta indica also known as neem, Indian lilac, or neem, an ancient tree native to India.

Why does neem oil for plants act as a natural insecticide? Among its main components is Azadirachtin, which helps repel insects and also prevents them from multiplying, hence its effectiveness against multiple pests.

Neem Oil Insecticide

The use of neem oil for plants as an insecticide is very widespread because it offers many advantages. To the fact that it is natural and fights numerous pests must be added its hydrophobic properties, something quite useful when used as an insecticide in outdoor crops. Neem oil is not easily washed off the leaves, much less by rainfall, which is why it is so effective.

Neem oil for plants can be generalized to all types of crops and is also authorized in organic farming. It can be used for vegetables, fruit trees, vines, olive groves, legumes, and ornamental plants. After this brief introduction about neem oil for plants, we can now explain how to mix neem oil for plants correctly.

What Is the Use of Neem Oil and Potassium Soap for Plants?

Neem oil, with a dark color, bitter taste, and intense aroma, is extracted from the seeds of the neem tree (Azadirachta indica), originally from India, and has multiple uses. Neem oil can be used as an insecticide, acaricide, fungicide, and insect repellent.

In addition to its wide field of action in terms of uses, it is also effective against:

  • Whitefly.
  • Mealybug.
  • Aphids.
  • Red spider mite.
  • Thrips.
  • Leafminers.

As for fungi, neem oil is very useful against mildew or powdery mildew, two of the most common and problematic in most crops and garden plants. It has also been proven effective against nematodes, so we can say that neem oil is universally used to combat almost any type of pest. The fact is that the composition of neem oil for plants is so complex that it is practically impossible for insects to adapt or create a certain resistance.

As for potassium soap, we are talking about another powerful ecological insecticide that mixed with neem oil is able to accelerate and strengthen all its properties. In addition, potassium soap has a powerful cleaning effect with which to eliminate the honeydew residues generated by insects. These residues that accumulate on the leaves can cause the appearance of fungi that are so problematic for your plants, as is the case of black mold.
