Control of Forest Disorders Compiled by James Ryan Doster Modified by Georgia Agriculture Education Curriculum Office ~ June 2004

Why Worry About Controlling Forest Disorders? Insects kill more trees than does fire. It is estimated that we lose 3 billion cubic feet of timber per year in the south as a result of insects and diseases. Insects and diseases affect trees in all stages of development.

Meet the Enemy: The Bark Beetles

See the Battle Field

What Can We Do About Bark Beetles? Good management is the key. Keep a sharp eye out for evidence of a problem. Cut Dead and dying trees rapidly. Chemicals (See current issue of Georgia Pest Control Handbook)

Control of the Pine Tip Moth Plant Resistant species such as Slash pine Remove and Destroy injured terminal buds

Control of the Pales Weevil Remove old stumps and slash prior to planting. Plant where pines were cut at least 6 months ago

Controlling Aphids Chemicals Predators such as Lady bugs.

Control of the Red-Headed Sawfly Parasites and Predatory insects Spray seedlings before eggs hatch

Control of Bagworms Chemicals in spring or summer. Hand removal burning

Controlling Gypsy Moths Difficult to Control Spraying Parasites Not established in Georgia.
