MaximumYield explains Neem Oil (Azadirachta indica)
Neem evergreen trees are said to be native to the Indian subcontinent, but they have been introduced to many different areas in the tropics. To obtain neem oil, seeds from the neem tree are crushed, and then combined with water or a solvent.
Neem oil is widely known for, used, and valued for its many medicinal properties. It has been used as an antiseptic, antihistamine, and an antifungal remedy. In addition to medicinal uses, neem oil is also used in gardening as a natural alternative to chemical pesticides.
Neem oil has a wide usage in organic farming as it can be used to control many common garden pests and diseases, and is not as harmful as chemical pesticides. This is because neem oil is biodegradable, organic, and nontoxic (when applied correctly). Some pests that can be killed or repelled by neem oil are aphids, snails, gnats, and mosquitoes, among many others. Additionally, neem oil is effective in preventing fungal diseases like mildew and black spot.
Also, unlike many chemical pesticides, neem oil will not harm beneficial garden insects like earthworms, butterflies, and honeybees. However, it should be noted that neem oil should not be sprayed directly on these beneficial insects. In addition, neem oil is considered to be nontoxic to humans (and other animals) so it can be used on crops and flowering plants.
Neem oil can be applied to plants as a foliar spray. However, application of neem oil should be light, as some plants can be killed by excessive neem oil administration. To use neem oil as an insecticide, plant leaves should be completly coated, particularly where pest or fungal problems are the worst. This application of neem oil should generally be given to plants once a week.
