Wetwood symptoms on tree trunk.
|Severity:||2 out of 5|
|Frequency:||3 out of 5|
|Symptoms:||The disease causes an internal pressure which, in turn, causes a waterish material called slime flux to ooze out through wounds in the bark. Slime flux is caustic (very alkaline). Generally, the bark is slowly bleached of its coloring where the slime flux runs down the outer bark. Often there is an unpleasant odor associated with the slime flux for a short period during the growing season.|
There is a complex of bacteria which cause wetwood and little is known about infection and the disease life cycle.
|Management:||There are no chemical controls at this time for wetwood. Occasionally a plastic pipe may be used to drain the slime flux in order to avoid additional weakening of trunk and branch crotches. Never use a metal pipe since the trees will eventually engulf the pipe. When the tree needs to be removed or trimmed, saws hitting the pipe may be damaged or worse the person using the saw may be injured or killed.|
