Are Herbicides Essential for Paddy Weed-control in East Asia?

Cho Young Son and Kipkoriony L. Rutto

Until the introduction of herbicides, weed control was one of the most difficult and labor-intensive cultural practices in rice cultivation. Herbicides have dramatically reduced the time spent on weed control and chemical weed control is presently the method of choice for eliminating weeds. However, herbicide application brings about water soil and atmospheric pollution: the most harmful by-products of commercial rice cultivation. New farming systems aimed at the reduction of herbicide dependence are being developed and tried in Korea and Japan. They include prescriptive pesticide usage, changes in soil management practices and water management, the introduction of natural enemies and integrated weed management. These new low-input cultivation methods require further study and offer unlimited challenges to researchers.
