Description and Injury
    Dieback refers to the dead branches or tips of branches in the crowns of otherwise apparently healthy trees. The cause is usually difficult to determine and may be due to poor drainage, herbicide damage, poor site, root rot, climate, flooding, disease, insects, or some unknown factor.

Control
    Plant healthy trees on proper sites, provide adequate weed control, and maintain the vigor of trees by pruning dead or diseased branches and thinning out undesirable trees in crowded plantations.
