Neem seeds contains up to 45% of a brown and bitter oil (neem oil or oil of Margosa). It has many medicinal uses and can also be used in lamps and for soap making.
Neem oil can control blackspot, powdery mildew, anthracnose and rust fungi.
How to Produce Neem Oil in Your Kitchen: Extract the kernels from the seeds by pounding the seed in a mortar and winnowing out the shells (use a separate mortar because neem seed is very bitter). Pls see the complete info here: https://www.farmersjoint.com/blog/crop-a...pesticide/
To spray neem oil on crops, you need to dilute it with water but neem oil will not mix with water. You need a surfactant to make it mix with water. A good home surfactant is liquid dish washing soap or soap. Don’t use detergent because they’re toxic to soil organisms. To make neem oil solution stick well to leaves, you can add saponins like aloe vera juice.
As an insecticide, use 4 teaspoons neem oil + 1 tablepsoon dish washing soap + 1 gallon water. Spray on plant or use as soil drench at 1l for 1m2 of soil. The best time to spray is during the cooler parts of the day – morning, late afternoon or evening. Doing so will prevent neem from harming beneficial insects like butterfly. For heavy infestation, apply weekly and for prevention, apply biweekly.
