Bacteria can provoke severe plants diseases even for the strongest kinds of plants like olive trees, oleander and similar. Viral diseases are generally caused by previous parasite attacks; in fact, viruses penetrate the inner parts of the plants, because of the holes that parasites create on them. On the same page there are fungal infections which affect the plant becoming very resistant and hard to eradicate. Powdery mildew, grey mold, rust and so on, are all part of these attackers.

Some can affect the roots and the woody parts of the plants, and they can be either appearing on fruit trees or vegetable plants. The cure is directly related to prevention.
