DescriptionBareroot Douglas-fir seedlings inoculated with Rhizopogon sp. and processed by standard nursery and reforestation procedures performed equally well whether planted near Douglas-fir stumps previously fumigated with two dosages of chloropicrin to control Phellinus weirii infection or near stumps not fumigated. Before stump-fumigation can be generally recommended for Phellinus-rehabilitation sites, the fate of the chemical and its derivatives.

- Potassium fertilizer applied immediately after planting had no impact on Douglas-fir seedling mortality caused by laminated root rot on a forested site in Washington State.
- Long-term effects of stump removal to control root rot on forest soil bulk density, soil carbon and nitrogen content.
- Application of chloropicrin to Douglas-fir stumps to control laminated root rot does not affect infection or growth of regeneration 16 growing seasons after treatment.
