The global population's growth has led to an increased demand for food production, consequently placing greater pressure on agricultural systems. Additionally, challenges linked to climate change, water scarcity, and diminishing arable land pose significant threats to the sustainability of farming. Weeds play a detrimental role in agricultural systems by competing for natural resources, thereby reducing both the quality and productivity of food production. To address this issue effectively and sustainably, it is essential to integrate various weed management methods, such as cultural, mechanical, and chemical approaches, in a balanced manner that does not harm the overall agrarian ecosystem. Consequently, it is crucial to avoid overreliance on intensive mechanization and herbicide usage, as the development of herbicide-resistant weed biotypes has become a substantial global concern, dating back to the emergence of 2,4-D resistance in the United Kingdom, Hawaii, the USA, and Canada in 1957. Given this situation, weed scientists must explore alternative weed management strategies that enhance agricultural productivity within the context of smart agriculture. Simultaneously, recent advancements in weed control technologies have the potential to increase food production levels, reduce input requirements, and mitigate environmental damage, thus moving us closer to more sustainable agricultural systems. Precision weed management (PWM) is one such alternative strategy that increases farm productivity by combining integrated weed management practices (chemical, mechanical, manual, and cultural) with site-specific, economically viable weed sensing systems (both aerial and ground-based). In order to help the farming community, weed experts should proactively focus their future research efforts on developing and integrating these techniques.
