Schweinitzii root and butt disease |
Phaeolus schweinitzii |
Schweinitzii root and butt rot is the most common brown cubical decay of Douglas-fir. It is common in other conifers species as well. The disease often starts in the roots when trees are young but is seldom seen causing butt rot until trees are mature or overmature. The cull usually only extends eight feet or less above the ground. Fruiting bodies are present on both of these examples but they are not commonly produced in this way. Usually they are found on the ground within a few feet of an infected tree. A single conk may indicate extensive infection throughout a stand. |

|
Root disease is often easily recognized from afar. Changes in tree density and clusters of young trees or brush assocaiated with tree mortality are good indicators of root disease. |
| 1241664 |
root diseases and rots |
|
If bark beetles attack dying trees they often hasten mortality. If mortality is hastened, the trees may not have time to shed many needles before they die. In this case, the crown may turn uniformly yellow or red. |
| 1241671 |

Schweinitzii root and butt disease |
Phaeolus schweinitzii |
Schweinitzii root and butt rot is the most common brown cubical decay of Douglas-fir. It is common in other conifers species as well. The disease often starts in the roots when trees are young but is seldom seen causing butt rot until trees are mature or overmature. The cull usually only extends eight feet or less above the ground. Fruiting bodies are present on both of these examples but they are not commonly produced in this way. Usually they are found on the ground within a few feet of an infected tree. A single conk may indicat extensive infection throughout a stand. |
