Pest and disease management

When managing pests and disease, Arbor Co understands the importance of maintaining plant and soil health. A  range of integrated management options, including the safe application of materials and products, provides effective treatments while protecting people, animals and the environment.

Your landscape trees and shrubs are valuable assets. Improper diagnosis and treatment may cause more damage than the initial concern. When tree health problems arise, early and accurate identification is an essential step in pest and disease management.  Arbor Co’s staff are skilled in pest identification and disease diagnosis and can advise on management options tailored to your situation.

Pests

If left unchecked, pest infestations can quickly reach damaging levels. However, not all insects are harmful to your plants – some are beneficial and help control pest insect populations. Arbor Co’s arborists are trained to correctly identify plant pests and the damage they cause.

Common tree pests encountered in south-eastern Australia include:

  • Elm leaf beetle
  • Mealybugs
  • Mites

Disease and disorders

Diseases are abnormalities in tree growth or function, and can be the result of either living (biotic) organisms such as fungi and bacteria or non-living  (abiotic) environmental stresses such as drought, waterlogging, or soil compaction. Diagnosis is often challenging as different diseases often cause similar symptoms.  Arbor Co’s arborists are skilled “disease detectives”, trained in diagnosis of tree disease problems.
