Tiny, soft-bodied insects that often cluster on young shoots and underside of leaves, feeding on plant sap. Prevention can be done by regular inspections and treatment can involve physically removing them, or using appropriate insecticidal soaps or sprays.
These pests can attack the tree, creating holes and tunnels in the bark and wood by over-wintering larvae. Using plant health management practices such as correct watering, mulching and avoiding wounding the tree can deter this pest. For infestation, use insecticides or parasitic nematodes.
This is a common fungal disease that forms a white to grayish powdery growth on the surface of leaves. Good sanitation practices, reducing overhead watering, and proper air circulation can prevent this disease. Fungicides can be used as a treatment method.
