Herbicide use is increasing in Asian riceproduction and is likely to continue in the near future. Direct seeding is also increasingly replacing transplanting as the dominant cropping system. There is a direct interaction between the availabilityof rice herbicides and the increase in use of direct-seeding technology. Direct seeding is viable in high-productivity irrigated systems if cost-effective herbicides are included in the control of weeds (Naylor 1996).
