Various studies have highlighted the effectiveness of different cultural practices. Using clean seeds and machinery can significantly reduce the introduction of weedy rice seeds into the field. This method, combined with herbicides like paraquat or glyphosate, has shown to reduce weed density by up to 53%. Thorough land preparation and rotating different rice establishment methods can help manage weedy rice effectively. Higher seeding rates and narrow row spacing have been found to reduce weed biomass significantly without affecting yield. Integrating allelopathic rice varieties with cultural management options can enhance weed suppression and reduce herbicide use. Proper water management, including flooding, can reduce weedy rice germination and growth. Combining cultural, mechanical, and chemical methods can sustainably reduce weed infestation and herbicide use. Cultural weed management strategies are essential for sustainable rice cultivation, especially in the context of increasing herbicide resistance and environmental concerns. These strategies not only help in reducing the infestation of weedy rice but also contribute to the overall sustainability of rice farming by minimizing the reliance on chemical herbicides. The integration of various cultural practices, such as the use of clean seeds, proper land preparation, crop rotation, and the adoption of allelopathic rice varieties, can create a more resilient and productive rice cultivation system. To ensure the long-term sustainability of rice cultivation, it is imperative for researchers, policymakers, and farmers to collaborate and promote the adoption of cultural weed management strategies. Future research should focus on optimizing these practices and developing region-specific guidelines to maximize their effectiveness. Policymakers should support initiatives that encourage the use of sustainable weed management practices, and farmers should be educated and incentivized to implement these strategies in their fields. By working together, we can reduce the impact of weedy rice and enhance the sustainability of rice production systems worldwide.
