Non-Chemical Management
- Do not plant susceptible species in areas where TCD is known to occur.
- Maintaining excellent tree health by providing adequate water and good nutrition may help slow progress of the disease, but will not prevent infection or eventual death of infected trees.
- In known TCD areas, do not move live plant material or raw wood (branches, chips, logs, firewood, stumps, etc.) from susceptible trees. Beetles are able to complete their lifecycle in cut wood and can also reinfest cut logs that retain any bark.
- Beetles have been observed to survive in large-diameter, freshly cut chips. However, chips will dry and become unsuitable host material for both beetles and fungus in a relatively short time, so chipping is considered one of the better ways to deal with infested materials.
- Wood from TCD-affected trees should be milled and used locally to prevent spread of WTB and TCD into new areas. Milled, bark-free lumber will not support WTB, but it is not known how long dried logs or slabs that retain bark can be reinfested.
