2018 Insect Disease Control Update:

  • Gypsy Moth
    • Despite reports of a fungus that attacks gypsy moths minimizing their population last season, our arborists have seen numerous signs that many escaped the infection and will be a factor in 2018.
    • If you witnessed moths fluttering around last July and see tan egg masses on tree trunks or undersides of limbs you should anticipate a problem this season.
  • Wintermoth
    • This damaging insect continues to be a problem. Part of the problem is its ability to show up where it had not been before and damaging plants that it had not desired in the past.
    • Predicting its future activity and degree of damage has been nothing short of impossible. However, if you witnessed moths fluttering around your outside lights around Thanksgiving history suggests your trees may be vulnerable.
  • Magnolia and Tulip Tree Scale
    • Specific to these plants only, difficult to control. Symptoms are black “soot” on stems, trunks, and leaves.
  • Azalea Bark or Cottony Camelia Scale
    • Infestations on azalea, rhododendron, holly, and yews have been observed in many locations. Areas in the shade along excess moisture from irrigation have been the most susceptible. Symptoms are small white masses along stems and under leaves along with the black “sootiness” on stems and leaves.
  • Fireblight
    • A disease that attacks mostly apples and crabapples. Limbs or sections of the tree will wilt, turn brown, and die.
  • Hemlock Woolly Adelgid and Elongate Scale
    • Specific to hemlocks. If you have hemlocks and we have been treating them they should be okay. However, if you have concerns with their appearance please let us know.

If you have any concerns about the well-being of your landscape plants, please contact us for a complimentary assessment.
