Beech leaf disease is a newly discovered lethal disease of beech trees believed to be caused by the nematode Litylenchus crenatae mccannii. [1] The symptoms of the disease appear as a dark green, interveinal banding pattern on the lower canopy foliage, eventually spreading throughout the tree.
Beech buds are distinctly thin and long, resembling cigars; this characteristic makes beech trees relatively easy to identify. The tree is monoecious, with flowers of both sexes on the same tree. The fruit is a small, sharply-angled nut, borne in pairs in a soft-spined, four-lobed husk. It has two means of reproduction: one is through the usual ...
Beech trees make up about 10% to 15% of the state’s total forest trees and up to 50% in some areas in Washington County, according to estimates from Fern Graves, forest stewardship program ...
Beech bark disease is a fungal infection that attacks the American beech through damage caused by scale insects. [39] Infection can lead to the death of the tree. [40] Beech leaf disease is a disease that affects American beeches spread by the newly discovered nematode, Litylenchus crenatae mccannii.
Research indicates potential use of P. pinnata as a food source for cattle, sheep, and poultry, as its byproduct contains up to 30% protein. [23] [24] As adaptive uses are increasing, the tree is being planted in former citrus growing regions that have declined in Florida and California because of disease and climate change conditions. [25]
Cryptococcus fagisuga, commonly known as the beech scale or woolly beech scale, is a felted scale insect in the superfamily Coccoidea that infests beech trees of the genus Fagus. It is associated with the transmission of beech bark disease [ 3 ] because the puncture holes it makes in the bark allow entry of pathogenic fungi which have been ...
