Soil Fumigation in Southern United States Forest Tree Nurseries

Soils in bareroot forest tree nurseries in the Southern United States have been safely and efficiently fumigated for three decades. The primary target organisms are the soilborne pathogenic fungi that cause root rot and damping-off on both conifer and hardwood seedlings. A formulation of 67 percent methyl bromide and 33 percent chloropicrin has consistently provided the most effective control of these diseases. Methyl bromide is presently used in over 90 percent of the southern nurseries. Alternative soil treatments are urgently needed. Guidelines and precautions on fumigants, application methods, benefits and costs, and registration and safety are presented. Factors affecting soil fumigation results are emphasized.
