Neem Oil is a naturally occurring, organic fungicide, insecticide and miticide for use on ornamentals, trees, shrubs, vegetables, fruit and nut trees. It can be used to control fungal diseases including black spot, powdery mildew, rust, needle rust, downy mildew, twig and tip blight, anthracnose, scab and flower, botrytis and alternaria. As an insecticide, it can be used to control insects such as aphids, spider mites, scale, whiteflies, beetles, leafrollers and other insect pests.
Apply Neem Oil at first sign of insects/mites for control of aphids, spider mites, scale, whiteflies, beetles, leafrollers, and other insect pests. Neem Oil is most effective when applied every 7 to 14 days. For heavy insect populations, spray on a 7 day schedule.
As a preventative fungicide, apply Neem Oil on a 7 to 14 day schedule until disease development is no longer present. To control disease already present, apply on a 7 day schedule until disease pressure is eliminated. Then continue spraying on a 14 day schedule to prevent the disease from reoccurring. To prevent rust leaf spot diseases, anthracnose and scab, begin applications at the first sign of spring budding. To prevent powdery mildew, apply in mid-summer or when disease is first detected. Continue applications until disease pressure no longer exists.
