ABSTRACT Water‐saving irrigation systems have been widely used in rice‐growing areas to adapt to water scarcity caused by climate change. However, the absence of a continuous water layer in these systems may favour weed germination, early emergence, and changes in weed composition and density, which could ultimately alter rice‐weed competition dynamics and necessitate a change in weed control strategies. Furthermore, the introduction of environmentally friendly weed control measures is in line with the current trend towards sustainable agriculture. The review consolidates the trend towards water‐saving rice cultivation, the ecological characteristics of weed populations in rice fields, and the effects of irrigation measures on weed population dynamics. A comprehensive understanding of these changes and their impact on rice‐weed interactions under different irrigation regimes is crucial for developing effective weed management strategies and improving weed control efficiency. These strategies not only contribute to the success of water‐saving rice cultivation but also support the expansion of its use in other growing areas by improving the efficiency of weed control.
