    Description

    Noninfectious tree diseases are those caused by nonliving agents. This type of disease is not transmitted from one plant to another. Extremes in temperature and water supply are the most common causes of this type of disease. Other causes are chemical substances in the soil, water, and air; transplant shock; and mechanical injuries. These nonliving disease agents are a major cause of loss in forest and landscape trees. Often they weaken the tree, enabling living agents such as fungi, bacteria, viruses, nematodes, and insects to attack and further injure or kill the tree. These living agents may build up on trees weakened by noninfectious agents and threaten the health of nearby trees.
