Strategies and Technologies in Weed Management: A Comprehensive Review

Abstract

The global burden of weed infestations presents profound challenges for agricultural productivity, economic profitability, and environmental sustainability. This comprehensive review encapsulates a broad spectrum of weed management strategies, examining traditional practices and probing into the frontier of emerging technologies. The review begins by elucidating the historical context and significance of weed management, substantiated by a diverse range of scholarly works. We explore the complex nature of weeds, including their definitions, classifications, and the multifaceted impacts they exert on agriculture, ecosystems, and, where applicable, human health. Traditional weed management strategies, encompassing manual, cultural, biological, and chemical controls, are discussed with a balanced evaluation of their merits and demerits, supported by a wide array of research. The core of this review is an in-depth analysis of burgeoning technologies in weed management, comprising precision agriculture, genomic approaches, and robotic weed control, among others. We provide case studies highlighting the effectiveness of these innovations, while also addressing potential implementation challenges. Further, the review engages in an evaluation of the environmental and socioeconomic implications of both traditional and modern weed management strategies. Discussion: Around the environmental footprint of weed control, the economic benefits, potential downsides, and labor issues are corroborated by substantial literature. Recognizing the limitations of current strategies and the challenges posed by the implementation of nascent technologies, the review culminates in an exploration of prospective directions for weed management. Considering the continuous technological advancements, a future replete with precise, sustainable strategies, and the advent of smart systems, fortified by artificial intelligence and machine learning is anticipated. Moreover, the importance of fostering interdisciplinary collaborations and recommendation of the development of policies that incentivize the adoption of sustainable weed management practices are underestimated. This review, consequently, serves as a sound source for researchers, practitioners, and policy-makers in charting the course of new endeavors in weed management.
