Weedy rice poses a significant challenge to rice cultivation, particularly in direct-seeded systems where its physical and physiological similarities to cultivated rice complicate management. This study explores various cultural weed management strategies aimed at reducing the infestation of weedy rice. Key strategies include the use of clean seeds and machinery, stale seedbed practices, thorough land preparation, crop rotation, high seeding rates, row-seeding, and the use of purple-colored cultivars. Additionally, flooding and crop rotation have shown promise in mitigating weedy rice issues. Integrating these cultural practices with ecological approaches, such as the use of allelopathic rice varieties and biological control methods, can further enhance weed management. The study highlights the importance of a multi-faceted approach, combining cultural, mechanical, and biological methods to sustainably manage weedy rice and reduce reliance on chemical herbicides. This integrated weed management framework not only addresses the immediate weed problem but also contributes to long-term agricultural sustainability and environmental health.
