An Integrated Approach to the Control of Weeds in Rice Fields

Rice is farmed as a dry-seeded upland, low-land, puddle-seeded, transplanted, and deep-water paddy crop. More than 350 weed species from 150 genera and 60 plant families have been recorded. The chapter provides a comprehensive overview of the botanical characteristics and ecological impact of the various species of plants commonly referred to as weeds (grasses, sedges, broad leaf, ferns, and algal weeds) that are found in rice fields. It also elucidates the diverse methodologies employed in the management of weeds, encompassing preventive measures, cultural practices, mechanical techniques, and biological and chemical interventions. The prudent integration of these methodologies is imperative for achieving cost-efficient and environmentally viable weed control in rice cultivation.
