A brief insight on precision weed management technologies

Abstract

The increasing global population intensifies demand for food production, placing significant strain on agricultural systems. This challenge is compounded by threats from climate change, water scarcity, and the decline of arable land. Weeds exacerbate these pressures by competing with crops for natural resources, leading to reduced yield and quality. To address this issue sustainably, a balanced integration of cultural, mechanical, and chemical weed control methods is essential, as overreliance on intensive mechanization and herbicides risks ecosystem harm and has led to the widespread issue of herbicide-resistant weeds. Recent technological advancements offer a pathway toward more sustainable systems by enabling precision weed management (PWM). This approach synergizes integrated weed management practices with site-specific, economically viable sensing systems to enhance farm productivity, reduce input requirements, and minimize environmental impact. Consequently, future research should focus on developing and integrating these innovative strategies to advance sustainable agriculture.
