Neem oil and neem cake are excellent for controlling diseases and pests in the garden due to their natural bioactive compounds. Neem oil contains azadirachtin, which disrupts the growth and reproduction of many pests, acting as a repellent, antifeedant, and insect growth regulator. It also has antifungal properties, helping to prevent diseases like powdery mildew.

Neem cake, a byproduct of neem oil extraction, enriches the soil with nutrients and acts as a natural pesticide. It suppresses soil-borne pests and diseases, promotes beneficial microbes, and improves soil health, making it a powerful organic amendment for sustainable gardening.
