Neem oil also has antifungal properties, making it useful for controlling fungal diseases like powdery mildew and black spot.

To use neem oil for pest control, mix it with water and a mild detergent to create an emulsion. Spray this solution onto the affected plants, making sure to cover both the upper and lower surfaces of the leaves. It is best to apply neem oil in the early morning or late evening to avoid direct sunlight, as this can cause leaf burn.
