The agriculture in Korea has been gradually changed from a labor-intensive type to a labor-saving one which aims to maximize productivity of labor. Herbicides have been utilized in rice farming since 1955. The consumption of herbicides rapidly increased during the last decade. However, the technology of weed control with herbicides has not been developed yet. For the dissemination of efficient weed control methods in farming, both research and extension activities on herbicide utilization should be strengthened. Appropriate research and guidance units on weed control should be established as early as possible, in order to provide the necessary technical information.
