Soil fumigation with methyl bromide-33% chloropicrin was the superior treatment for controlling black root rot of loblolly pine (Pinus taeda) seedlings. The severity of root rot was reduced significantly when soil was fumigated with DD-mencs or drenched with benomyl but was not reduced when soil was drenched with thiabendazole. Both benomyl and thiabendazole soil drenches reduced ectomycorrhizal development, but neither soil fumigation treatment affected it.
