Comparison of Three Soil Fumigants in a Bareroot Conifer Nursery

Nursery soil was treated with dazomet (Basamid®), metam sodium (Soil Prep®), or methyl bromide-chloropicrin (Dowfume MC-33®) or left untreated (control). All three chemical treatments resulted in reduced levels of pathogenic fungi in the soil and improved survival of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedlings and stand density. Seedling growth was the same regardless of treatment in the first growing season. Some growth differences were seen after the second growing season. Height and caliper variations were least with the dazomet treatment. Utilization of these chemicals in conifer nurseries is discussed. Tree Planters' Notes 39(4):16-22 ; 1988.
