Fungicides in the Nurseries

Research on forest tree nursery diseases in the United States has had four peaks of activity, roughly 20 years apart, since the early 1900's. Activity was high about 1915 with the establishment of several forest nurseries in the U. S. Research declined until 1935, when it gained momentum with the establishment of the Prairie States Forestry Project and other planting programs during the Great Depression. Activity again was reduced during World War II and only increased about 1955 with the soil bank and other planting programs, and with the need to control nematodes and serious root rots chiefly in southern nurseries. The pressure for research was reduced following the development of soil fumigation treatments which effectively reduced nematode damage, root rots, and damping-off losses. In contrast, in Canada, where soil fumigants have been used only sparingly there has been continuing investigation of nursery diseases, particularly diseases caused by soil-borne pathogens. Today in the U. S. there is an increase in seedling disease research prompted in part by the need to develop control measures for diseases of seedlings produced in containers.
