Soil Fumigation Evaluations in White Pine Seedbeds and other Nursery Investigations

In 1956 extensive evaluations of various fumigants and fungicides was completed at the east nursery at New Kent 1 and at the Charlottesville nursery. A complete report of the results of these trials is available in mimeographed form, entitled "Forest Tree Nursery Investigation--1956-57", March 26, 1958. These evaluations were part of an overall investigation into the causes of annual midsummer mortality of 1-year white pine seedlings at New Kent. A particularly favorable growing season in 1956 which resulted in only minor differences between treatments, and the failure of any of the materials tested to reduce midsummer mortality, resulted in a tentative conclusion that none of the fumigants or fungicidal drenches evaluated at New Kent was "financially" feasible. Nonetheless, all seedbeds planted to white pine in 1957 were drenched with Vapam (60 gal. per acre). Again we experienced the usual loss of from 20 to 30 percent of the germinated seedlings in late June and early July.
