Use of Pesticides in Bareroot Hardwood Seedbeds in the Southern United States
2008
South, David B. | Carey, William A.
Pesticides are used in bareroot hardwood nurseries to avoid losses and to reduce the cost of seedling production. In 2001, the Auburn University Southern Forest Nursery Management Cooperative sent a questionnaire to all its nursery members to assess the level of pesticide use. Fifteen questionnaires were returned from nurseries that were growing hardwoods. One objective of the survey was to determine the relative importance and use rates of pesticides in hardwood nurseries. Results indicate that, in growing a million hardwood seedlings, nursery managers use about 944 kg of fumigants, 13 kg of herbicides, 3 kg of insecticides, and 0.6 kg of fungicides (weights are expressed in terms of active ingredient). The overall cost of pesticide treatments account for about 3 percent of the crop value. Documenting actual pesticide usage is one way to assess how nursery practices have evolved over time.
