Aerobic rice is a new way of cultivating rice that requires less water than lowland rice. Direct sown aerobic rice suffers more due to weed menace as the weeds and rice compete for growth factors together. Achieving higher rice grain yields under aerobic conditions requires better weed management practices. Hence, the aerobic rice should be focused primarily on efficient weed management to make aerobic rice cultivation more efficient in terms of returns on farmer investments and use of water resources. Most upland and aerobic rice growers in Asia manually weed their crops two or three times per season. Both pre- and post-emergence herbicides can be used in aerobic rice fields; however they are effective only if properly used. The application of pre-emergence herbicide like pendimethalin, azimsulfuron, pyrazosulfuron and penoxsulam play significant role in controlling weeds. Similarly, post-emergence bispyribac-Na herbicide also considered to be an alternative/ supplement to hand weeding. There is a need to develop sustainable weed management strategies that will give rice a competitive advantage over weeds. The use of herbicides along with appropriate timing, rotation, and combination needs to be integrated with other cultural approaches which ultimately result into higher productivity in aerobic rice.
