An Evaluation of the Effects of Dazomet on Soil-Borne Diseases and Conifer Seedling Production-USDA Forest Service Lucky Peak Nursery, Boise, Idaho

An evaluation was conducted at the USDA Forest Service Lucky Peak Nursery to investigate efficacy of dazomet (Basamid® granular) soil fumigant to reduce soil populations of Fusarium and Pythium spp. and subsequent post-emergence damping-off and root diseases. Effects on ponderosa and lodgepole pine seedling establishment, density, growth, and biomass production were also evaluated. Results were compared with soil fumigation with methyl bromide/chloropicrin (MBC) and fallow (non-fumigation) which had been done previously in nearby fields.
