Insect/ Disease Management

For trees and other plants, the Midwest can be hazardous– there are over a hundred different species that could pose a threat to your trees.

One of the issues with treating insects is that while some may be damaging, others may actually be beneficial to the health of your trees, and knowing the difference is vital.

Our trained and certified arborists are able to quickly identify and recommend the appropriate actions for both removing harmful insects and preserving those that do a tree good.

The Top 10 Threats to Trees and Plants in the Midwestern United States are as follows:

  • Emerald ash borer (EAB)– This metallic green beetle is an invasive species which can cause serious damage and death to Ash trees.
  • Gypsy moth – The gypsy moth is a known pest– its larvae feeds on over 500 trees and plants and the species is considered to be one of the most destructive insects in the U.S.
  • Cankerworm – This moth hatches larvae that feed on deciduous trees as well as on shrubs. When their eggs are hatched, they release small worms that first , turning into numerous inch-long worms that remove the leaves from the tree before killing it.
  • Bark beetles – These are small beetles, black in color, that barrage trees that have already been weakened by disease, drought or other conditions.
  • Tent caterpillars – These caterpillars spin their webs in tents and remove the leaves from trees, stunting the tree’s growth while damaging it’s overall health.
  • Flat-headed borers – this species includes the bronze birch borer and the two-lined chestnut borer. Once their larvae hatch, they burrow into the bark of the tree and begin feeding.
  • Weevils – These beetles lay their larvae in crops– the larvae then cause massive damage to the crop through feeding.
  • Spider Mites – These mites dwell on the underside of leaves, eating through the plant– they resemble tiny spiders.
  • Aphids – Aphids are also called plant lice– they’re a minute species of insects that suck the sap from plants, thereby destroying them.
  • Diseases– Disease is also a significant threat to trees and shrubs, causing damage through a wide variety of microorganisms like fungi and bacteria– they often weaken the tree or plant, leaving it vulnerable to other stressors such as drought, extreme temperatures and pollution.

Diseases are often the result of multiple causes, which can make both identification and duplication difficult and often require professional intervention to allow for accurate diagnosis and potent treatment.

The Top 10 Diseases that Pose a Threat to Plants in the Midwest are:

  • Oak wilt
  • Phytophthora root rot
  • Dutch elm disease
  • Wood decay
  • Anthracnose
  • Needlecast
  • Verticillium wilt
  • Pinewood nematode
  • Iron and manganese chlorosis
  • Drought
