NEEM OIL
Neem oil is a vegetable oil pressed from the seeds of the neem (Azadirachta indica), an evergreen tree which is endemic to the Indian subcontinent and has been introduced to many other areas in the tropics. It is the most important of the commercially available products of neem for organic farming and medicines.
As an organic pesticide, neem oil is commonly used in gardening to protect plants from pests like aphids, spider mites, and whiteflies. Its natural compounds repel harmful insects, making it a safer alternative to chemical pesticides.
In addition to gardening, neem oil is renowned for its benefits in skin care. Rich in fatty acids and antioxidants, it helps combat acne, soothe dry skin, and reduce signs of aging. Many people use neem oil in DIY beauty treatments, adding it to lotions, soaps, and shampoos for a natural skin boost.
Neem oil's effectiveness as a natural solution makes it popular in organic farming, personal care products, and home remedies. Whether you're a gardener looking for a natural pest control solution or someone seeking healthier skin, neem oil offers a powerful, eco-friendly option.
Neem oil varies on the following color:
Golden yellow
Yellowish brown
Reddish brown
Dark brown
Greenish brown, or bright red.
Meem oil has a rather strong odor that is said to combine the odours of peanut and garlic. It is composed mainly of triglycerides and contains many triterpenoid compounds, which are responsible for the bitter taste. It is hydrophobic in nature; in order to emulsify it in water for application purposes, it must be formulated with appropriate surfactants.
Neem oil for Organic Farming
Neem oil is a valuable tool in organic farming due to its various agricultural benefits and low environmental impact. Here are some common uses of neem oil in organic farming:
Pest Control:
Neem oil is effective against a wide range of agricultural pests, including aphids, whiteflies, thrips, mites, caterpillars, beetles, and nematodes. It disrupts the growth and development of insects, inhibiting feeding, reproduction, and molting. Neem oil acts as a repellent, antifeedant, and oviposition deterrent, reducing pest damage to crops.
Fungal Control:
Neem oil has antifungal properties that make it effective against various fungal pathogens, such as powdery mildew, downy mildew, anthracnose, rust, and leaf spot diseases. It inhibits the growth and development of fungal spores and mycelium on plant surfaces, preventing disease establishment and spread.
Insect Growth Regulation:
The primary active compound in neem oil, azadirachtin, acts as an insect growth regulator (IGR) by disrupting the hormonal balance and development of insect pests. It interferes with molting, metamorphosis, and reproduction, leading to reduced pest populations and crop damage.
Nematicidal Activity:
Neem oil exhibits nematicidal properties that make it effective against soil-dwelling nematodes, which can cause significant damage to crops. It inhibits the movement, feeding, and reproduction of nematodes, reducing their population and mitigating root damage and yield loss.
Biological Control:
Neem oil acts as a biopesticide and biofungicide, providing a natural alternative to synthetic chemical pesticides and fungicides in organic farming systems. It is compatible with beneficial insects, such as pollinators and natural enemies of pests, minimizing negative impacts on non-target organisms and promoting ecological balance.
Soil Amendment:
Neem cake, a byproduct of neem oil extraction, is used as an organic fertilizer and soil conditioner in organic farming. It enriches the soil with nutrients like nitrogen, phosphorus, potassium, and micronutrients, improving soil fertility and structure. Neem cake also contains natural pesticides and nematicides, contributing to pest and disease management in the soil.
Residue Management:
Neem oil residues break down rapidly in the environment, minimizing the accumulation of harmful chemical residues in soil, water, and food products. This reduces environmental pollution and ensures food safety in organic farming practices.
Integrated Pest Management (IPM):
Neem oil is an integral component of integrated pest management (IPM) programs in organic farming, which combine various cultural, biological, and mechanical control measures to manage pests sustainably. It is used in conjunction with other pest control tactics to enhance efficacy and reduce reliance on synthetic chemicals.

It can be used as a household pesticide for ant, bedbug, cockroach, housefly, sand fly, snail, termite and mosquitoes both as repellent and larvicide.Neem oil also controls black spot, powdery mildew, anthracnose and rust fungi.
Neem seed oil has also been found to prevent implantation and may even have an abortifacient effect similar to pennyroyal, juniper berries, wild ginger, myrrh and angelica. The effects were seen as many as ten days after fertilization in rats though it was most effective at no more than three days. (Sinha, et al., 1984)[not specific enough to verify]; (Lal et al., 1985)[not specific enough to verify]. In a study on rats, neem oil was given orally eight to ten days after implantation of the fetus on the uterine wall. In all cases, by day 15, the embryos were all completely resorbed by the body. The animals regained fertility on the next cycle showing no physical problems. Detailed study of the rats revealed increased levels of gamma interferon in the uterus.
The neem oil enhanced the local immune response in the uterus.(Mukherjee, 1996)[4][not specific enough to verify] Post coital use of neem oil as birth control does not appear to work by hormonal changes but produces changes in the organs that make pregnancy no longer viable (Tewari, 1989)[not specific enough to verify] (Bardham, 1991)[not specific enough to verify].
Neem seed oil has also been used as a renewable source for the preparation of polymeric coatings. It has been converted into various polymeric resins, including polyesteramides and polyetheramides. These resins may be utilized further for preparation of polyurethane coatings.
Neem oil is a natural oil extracted from the seeds of the neem tree. It has been used for centuries in traditional medicine and skincare due to its antifungal, antibacterial, and anti-inflammatory properties.
