Moreover, neem oil can be used as fungicide, insecticide, acaricide and nematicide and could be used best alternative in organic farm. The neem cake produced organic fertilizer, containing high organic matter and 13.8% nitrogen, Phosphorus (0.5% to 1.0%) and potassium (1.0% to 2.0%). The dual activity of neem cake as fertilizer and pest repellent has made it a favored input. Neem cake is a by-product of oil extraction and since it represents 70% of the original seed by weight or volume. Neem is used in storage; pests can be kept away from the grain for a whole year; but if the grain is already infected with pests the protection will not work.
