We all have problems with insects and if we like to consume what we grow, we will strive to use natural insecticides. That is why we have decided to show you how to make insecticides from neem oil.

Nim (Lat. Azadirachta indica) is a tree of the genus Azadirachta. Most commonly it grows in India, but it also exists in Pakistan and Myanmar, while thanks to man, it has subsequently spread beyond its core growth area, to Africa, America, Australia, and the Pacific Islands.

Neem is a fast-growing tree, which can grow up to 65 feet in height (sometimes up to 130 feet), with light green leaves. In India, neem is considered a sacred tree and is known for its healing properties. Every part of this tree has healing value – from flowers, fruits and seeds to twigs, juice, and roots. Neem oil is one of the oldest medicinal oils and is obtained by pressing seeds.

The plant is used in India similarly to lavender, it is placed in the laundry cabinets and is also used for storing rice. In the tropics, dry leaves are burned to get rid of mosquitoes. The leaves are also used in some Hindu religious ceremonies. It is also used in traditional Ayurvedic Indian medicine.

The use of neem in agriculture

Neem is recognized as a natural product that has a lot to offer in solving global problems in agriculture, the environment, and health problems. It is considered a valuable tool for sustainable development. Oil extracted from the seed of a neem tree is a powerful natural insecticide, capable of disrupting the life cycle of insects at all stages (adults, larvae, and eggs), making it an excellent resource for the eco gardener.

It is biodegradable and non-toxic to pets, birds, fish, and other wildlife, and is effective against a variety of common garden pests, as well as a natural fungicide that can fight mold and other fungal infections on plants, reports. It can be found in many garden shops or natural food markets

Strange wood and hundreds of its active compounds do not have any toxic reactions, so they are useful in protecting plants and producing them

Neem powder

The neem powder is also used in bio fertilization as a protection against pests and fungal diseases. There are several ways to prepare, so here are some recipes:

Neem tea

Pour 2 tablespoons of neem powder with 0.4 gallons of boiling water, stir and let stand. While cooling, mix with 1.6 gallons (1: 4 portions) of water and spray. After the rain, repeat the spraying. This protects plants from fungal diseases but also acts as a systemic insecticide, so it is used in those parasites that suck up and eat the leaves and plant juices. plants

Submerged Neem powder

Soak 2 tablespoons of neem with 0.4 gallons of plain water, without cooking, and let stand overnight. The next day, mix with 4 portions of water and spray. You can add water to the rest of the precipitate and spray again after standing, and finally use the precipitate as a fertilizer.

Recipe from India

This recipe was brought to me by a friend directly from a trip to India, where such a large number of farmers cultivate plants. In 0.5 gallons of water put 3 tablespoons of neem and 1 oz of tobacco. Let this stand for 10 days, and mix 1/4 of the preparation with 0.3 gallons of water, and spray the plants daily. It is sprayed either in the early morning or late at night to avoid spraying bees and other beneficial insects.

How To Make An Insecticide From Neem Oil

Neem oil is obtained by cold pressing the neem tree fruits. It contains limonoids and saturated fatty acids that have a beneficial effect on the skin. It is used as a concentrate or mixed with other base oils ONLY for external use.

Neem fruits are also used as bio-pesticide, either as oil or as neem fruit powder.

Here is how to make natural insecticide with neem oil yourself.

To create a 1% solution you need:

  • 0.4 gallons of hot water
  • a few drops of dishwasher detergent (best eco)
  • 2 teaspoons of neem oil

You mix everything in the sprayer and spray the attacked plants. Use the product the same day, do not leave it in the sprayer. Spray the leaves well on the inside too, and you can also spray the soil around the plant.

To simplify, I put 2 tablespoons of neem oil, warm water and some eco detergent for 0.4 gallons of the sprinkler. Hot water is essential for better oil dissolution, and detergent is essential for better dispersion and adhesion to plant leaves.

Don’t expect miracles – neem oil is not an instant insecticide, which means you won’t find dead pests right after spraying around plants. It acts as a systemic insecticide on a hormonal level over several days.

Although neem works systemically, therefore through sprayed plants, you should still be careful not to spray useful bugs such as bees as they may suffocate. Therefore, it is sprayed only in the early morning or evening. In my experience in the evening, it is better because there are a lot fewer bees outside than in the morning.

Personally, I use neem oil to attack pests that suck on plant juices, such as cabbage. It can also be used, for example, stink bugs that suck on tomato fruits. It also helps with pests that devour leaves, such as boxwood moths. If sprinkled with neem oil on time, you can protect the boxwood bush from these devouring caterpillars.

When suppressing fungal diseases like tomato blight, I use neem tea, to which I add a drop of detergent and 2 tablespoons of baking soda. I have tested the effectiveness of neem in combating fungal diseases of tomatoes on my bio garden and it really works.
