Sooty Mould is another problem to watch out for. This is a fungal problem that needs to be treated with PestOil . Sooty Moulds are fungi which cover plant leaves, stems and twigs in a black sticky substance. In almost all cases, the Sooty Mould is secondary to an infestation of insects that secrete honeydew. These insects include aphids, scale, mealybugs and white flies. Treating the insects will remove the source of the honeydew and dry up the Sooty Mould, which will eventually fall or wash off the foliage. The mould itself does not feed on the plant, however as it covers the leaf surface, it is blocking light and reducing photosynthesis, essential for plant growth. Learn more Citrus Leaf Miner.

Some bird species will consume these pests but often not enough to control and prevent damage to plants. The bugs suck the sap from young shoots, fruit and flowers in summer.
