I noticed my citrus tree leaves are curling, and they are black like there us a fungus on them, and there are white powdery spots on the undersides.
Bonide Systemic Insect Control is not labeled for use on citrus trees. Please consider using Fertilome Triple Action with Neem Oil. It is a miticide, fungicide, and insecticide that is labeled to be used on just about every type of plant. You will mix 1 fl. oz per gallon of water and spray plants until they are wet but not dripping.
