American Mistletoe (Phoradendron serotinum var. serotinum) Infection In Trees

Monograph on the tree pest American mistletoe (Phoradendron serotinum var. serotinum).

Every Winter people notice mistletoe. Whether in holiday greenery or in deciduous trees, mistletoe is a

visible symbol of tree damage. Mistletoe negatively impacts both tree health and structure. Mistletoe is a

parasite which initiates branch decline and loss, wood decay and discoloration, animal and pathogenic entry

points into a tree, and oxygenation and drying of wood. Mistletoe commandeers growth resources from trees.

Early intervention is critical to maintaining tree health and structural integrity.

Mistletoe has a long history of being noticed and celebrated by humans. Spiritual blessings and curses

were centered around mistletoe. Some forms of mistletoe, especially when infecting a particular individual tree

or species of tree, were important in naturalistic religions or rites. The term “mistletoe” has a much less exotic

and revered background. Because mistletoe was thought to be propagated by bird droppings, the term mistletoe

is derived from Anglo-Saxon for “a twig with bird droppings,” or distantly derived from “a different kind of

twig.” Kissing under this parasite has many meanings.
