An oil extracted from the seeds of the neem tree is a powerful natural insecticide, capable of disrupting the life cycle of insects at all stages (adult, larvae, and egg), making it a great resource for the organic gardener. Neem oil acts as a hormone disruptor and as an "antifeedant" for insects that feed on leaves and other plant parts. Neem oil is biodegradable and is nontoxic to pets, birds, fish, and other wildlife, and is effective against a variety of common garden insect pests, as well as being a natural fungicide that can combat powder mildew and other fungal infections on plants. It can be found at many garden stores or natural foods markets. To use neem oil as an insecticide, either follow the instructions on the bottle, or start out with a basic mixture of two teaspoons neem oil and one teaspoon of mild liquid soap shaken thoroughly with one quart of water, and then sprayed on the affected plant foliage. Neem oil can also be used preventatively by spraying the leaves of plants that are often ravaged by pests, before they're actually infested.
