Drawing on literature reviews from ongoing unpublished research, research reports and symposia carried out on various aspects of the importance, ecology, biology and control of weedy rices, this publication also highlights global economic and environmental problems created by weedy rices, including red rice types.

Significance of weeds in rice farming; Rice weeds of world importance; Weed control; Principles of herbicide use; Principal rice herbicides; Weed control in irrigated rice; Weed control in rainfed lowland rice; Weed control in upland rice; Weed control in deepwater and floating rice; Management of some difficult weeds.

Dry-direct seeded rice (DSR) is an emerging resource-conserving and climate-smart production technologies in the changing climatic condition and the areas where the key resources such as water and labor are the major limiting factors to rice cultivation. The success of DSR largely depends on its proper early establishment and judicious weed management. A uniform stand of adequate rice plants is critical to achieving high yields, therefore seed rate and sowing date are very important for DSR. Due to different methods of land preparation between DSR and transplanted rice, the soil conditions are different in these systems, therefore, nitrogen fertilizer management is very important to DSR. Chemical weed management is a must in DSR to reduce weed management cost, however, considering the negative effect of herbicide on the environment and developing of herbicide resistance biotypes, weed management needs an integrated approach. Inside this book, you'll find the effect of sowing time and seeding rate for the establishment of DSR and the best fertilizer and weed management approaches for its sustainable production.
