Sycamore Tree Diseases - Symptoms & Control

Sycamore Tree Diseases 


Anthracnose

  • Symptoms

    • Dead twigs and branches have sunken cankers. Bud death followed by new bud formation and more bud death results in witches' broom-like proliferation of branch ends as well as very crooked branching patterns. Black fungal fruiting structures are visible on the bark covering newly killed twigs early in the Spring. Young shoots are killed. Leaves, especially on lower and inner branches, are blighted and fall early in the season only to be replaced y new leaves in mid-season. Tan, dead areas expand along leaf veins. Large, irregularly shaped ares are killed along the leaf margins and between the veins.

Bacterial Leaf Scorch

  • Symptoms

    • Oldest leaves brown along their margins and eventually between the veins beginning in mid to late Summer on one branch or a few branches on inner and lower portions of the tree. A brown band sometimes develops between the brown and green tissue of the leaf. The browning of leaves progresses to include more leaves toward the ends of branches. Infected trees have delayed bud break in the Spring and produce smaller-than-normal leaves.
  • Management

    • Leafhoppers and Spittle Bugs carry the bacteria from tree to tree. Promote plant vigor by protecting the tree from stresses. X. fastidiosa from Elm does not infect Sycamore or vice-versa

Canker Stain

  • Symptoms

    • London Plane and Sycamore trees have sparse foliage, small leaves, and elongated sunken cankers on the trunk and larger branches. Beneath the cankers, the wood is stained bluish black or reddish brown. Viewed in cross section, the discolored wood is wedge shaped with the point of the wedge extending toward the center of the trunk or branch.
  • Management

    • Since the fungus enters only through wounds, pruning tool, ropes, ladders, and other equipment must be disinfested immediately after use on a tree before proceeding to another tree. Do not use wound paints since brushes efficiently move spores from tree to tree. Sap-feeding beetles can also transmit the fungus.
