Neem protect Moringa leaves and Environment
The Neem tree is excellent to use as Biopesticide for farming and protect Moringa leaves but has more benefits…..
The Neem tree is very beneficial for the safeguard of the environment against pollution. And stops worms, insects, butterflies, grasshoppers etc from eating the harvest as Moringa leaves (they know this is healthy diet) without destroying everything with chemicals.
- Scientific names: Azadirachta indica.
Common names: Neem, margosa, nim, nimba, nimbatiktam , Arishtha, PraNeem.
In Khmer : Sdau, Sdov or Sdaw.
The Neem tree is growing everywhere in Cambodia, easy to grow also by drought. I’m still wondering that so less farmers using it. Neem also helps in restoring and maintaining soil fertility which makes it highly suitable in agro-forestry. The unbelievable bad smell, the foul odor and bitterness having fungicidal, insecticidal and nematicidal properties of this leaf makes sure the insect’s don’t like to eat your harvest or the Moringa leaves.
Neem extracts have been approved by the U.S. Environmental Protection Agency for use on food crops. It has been proven in various research studies that Neem is non-toxic to birds, beneficial insects or humans and protects crops from over 200 of the most costly pests.
Articles written in Sanskrit show that people have been using Neem for thousands of years. Neem is also called ‘arista’ in Sanskrit- a word that means ‘perfect, complete and imperishable’.
In the Cambodian “Dictionnairre Des Plantes utilisees au Cambodge” it’s named as “Azadirachta Meliaceae” also called in Khmer as Sdau, Sdov or Sdaw. Neem is used in parts of mainland Southeast Asia, particularly in Cambodia.
Neem is also used as an insect repellent, and oral dentifrice, and in traditional medicine to treat malaria, diabetes, worms, and cardiovascular and skin diseases. We at our farm see many times the yellow worm (from the butterfly) eating from our Moringa leaves.
What is Neem? The Neem is a large evergreen tree that grows up to 20 m in height, with spreading branches that form a broad crown. The plant is found throughout India and neighboring regions, where it is cultivated commercially. The plant is often confused with Melia azedarach L., the chinaberry or Persian lilac. Leaves grow alternately with leaflets containing 8 to 19 leaves. The tree yields high-quality timber and a commercial gum.
Making large amounts of a watery Neem leaf extract:
Cut the old leaves of this tree. Cover the Neem leaves with water at a ratio of one kilogram of leaves to five liters of water. Let the leaves soak a few days in the water mix, clean the extract with a towel or filter it through a proper filter paper so your leaves and dirt staying out of the spraying substance (this will spray easier) and spray the leaves as you are usual spraying. Because it’s not a chemical substance, if you see insects which are eating your leaves than you have to spray around 3x times a week on the leaves. Don’t heat or boil the mix. Heat will actually lower the Neem leaves in content of the Neem leaf extract.
Pure Neem Extract vs. Neem Oil : Neem oil is more active as Biopesticide for organic farming as from the Neem leaves. Neem oil is a vegetable oil pressed from the fruits and seeds of the Neem.
Locals in Cambodia like the Neem seeds very much. It’s better to grow the Neem (Sdau) tree by yourself, collect the seeds and press them to oil. Because the oil makes the leaves slippery and the foul odor and bitterness makes that the insect stay away.
It is the most important of the commercially available products of Neem for organic farming and medicines.
The Neem oil yield that can be obtained from Neem seed kernels also varies widely in literature from 25% to 45%. Neem oil is not used for cooking purposes. It’s also used for preparing cosmetics (soap, hair products, body hygiene creams, hand creams).
Traditional Ayurvedic uses of Neem include the treatment of acne, fever, leprosy, malaria, ophthalmia and tuberculosis. Various folk remedies for Neem include use as an anthelmintic, antifeedant, antiseptic, diuretic, emmenagogue, contraceptive, febrifuge, parasiticide, pediculocide and insecticide. It has been used in traditional medicine for the treatment of tetanus, urticaria, eczema, scrofula and erysipelas. Traditional routes of administration of Neem extracts included oral, vaginal and topical use. Neem oil has an extensive history of human use in India and surrounding regions for a variety of therapeutic purposes. Puri (1999) has given an account of traditional uses and therapeutic indications and pharmacological studies of this oil, in his book on Neem.
Toxicities: Neem oil and other Neem products, such as Neem leaves and Neem tea, should not be consumed by pregnant women, women trying to conceive, or children Neem extract Its also effective to cure ringworm, eczema and scabies. Lotion derived from Neem leaf, when locally applied, can cure these dermatological diseases within 3-4 days in acute stage or a fortnight in chronic case. A paste prepared with Neem and turmeric was found to be effective in the treatment of scabies in nearly 814 people 100.
Besides the amazing effect as organic pesticide it’s also excellent for your health. With some 700 preparations described almost every part of the Neem tree is used in traditional medicine. The tender leaves have been used in the treatment of worm infections, ulcers, and cardiovascular diseases, as well as in the treatment of leprosy.
Neem leaves are also dried and burnt in the tropical regions to keep away mosquitoes.
Neem leaves are also used in storage of grains and seeds storage’s.
If you google on Neem, you will see: Neem oil is a naturally occurring pesticide found in seeds from the Neem tree. It is yellow to brown, has a bitter taste, and a garlic/sulfur smell. It has been used for hundreds of years to control pests and diseases. Components of Neem oil can be found in many products today.
