Extract

Public participation in home vegetable gardening and small farm operations is increasing in North America. This is expected to intensify the use of insecticides and disproportionately increase public exposure to them. For instance, von Rurnker et al. (1972) estimated that on an area basis homeowners in the midwestern United States applied ca. 5.0 lb of pesticides per acre. This amount when compared with 1½ to 3 lb per acre applied by the farmer suggests that backyard gardens receive a heavier pesticide application than most other land areas in the United States. It is, therefore, important to develop ecologically less aggressive control methods for small farm operations.
