This study systematically reviewed the technical principles, research and development status of herbicide-resistant transgenic rice and its specific impact on weed management. It was found that transgenic herbicide-resistant rice can significantly improve the efficiency of weed control, reduce the amount of herbicide application, and reduce the loss of weed competition in the field. However, it also pointed out that the long-term use of a single herbicide may lead to the accelerated evolution of weed resistance, increasing the risk of non-target plants and soil ecosystems being affected. In addition, transgenic rice planting may also lead to adjustments in agronomic management patterns and potential changes in agricultural ecosystems. This study emphasizes that a multi-strategy integrated weed management (IWM) system should be combined to implement a sustainable strategy of herbicide rotation, diversification of action mechanisms, and combination of mechanical and ecological control methods, and strengthen ecological risk monitoring and assessment to achieve the coordinated development of transgenic herbicide-resistant rice and green agriculture. This is of great significance to ensuring the safety of rice production, reducing environmental pollution, and promoting sustainable agricultural development.
