Abstract

Bareroot 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.
