Special Issue Information

Dear Colleagues,

Weed control remains one of the most persistent and costly challenges in modern agriculture, particularly under the increasing pressure to reduce herbicide use, manage resistance and promote sustainability. Traditional methods—manual, mechanical, or chemical—are increasingly challenged by the need for environmental stewardship, labor shortages and the global imperative to secure food supply. The rising demand for sustainable and efficient crop production has catalyzed transformative changes within agricultural engineering, particularly in weed management. This Special Issue aims to address these pressing concerns by showcasing the latest advancements in precision weeding, leveraging cutting-edge technologies such as machine learning, robotics, sensor fusion and big data analytics.

Purpose:

The purpose of this Special Issue is to advance the science and technology of precision weeding, accelerating the transition from proof-of-concept trials to robust, scalable solutions in commercial agriculture. Our intent is to create a collaborative platform where researchers, technologists, and practitioners from diverse backgrounds can share breakthroughs, practical insights, and case studies.

Relationship to the existing literature:

While comprehensive reviews and research articles have examined specific facets of precision weeding such as machine vision methods or robotics, the landscape is rapidly evolving with the integration of AI, IoT, and big data. This issue seeks to bridge existing knowledge gaps by providing a unified, multidisciplinary perspective and highlighting real-world implementations, system integration challenges, and scalability. The collected works will both supplement the current literature by presenting novel methodologies and contextualize these within broader trends in sustainable agricultural technology.

Topics of Interest (but not limited to):

  • Technological innovations, including computer vision, machine learning algorithms, real-time detection, and robotic systems;
  • Field testing, hardware constraints, and climate variability;
  • Data governance, AI ethics, adoption hurdles, and public trust;
  • Analysing economic viability, environmental benefits, and relevant case studies;
  • Cross-regional perspectives, comparing smallholder and industrial farming practices;
  • Incorporating open-source toolkits and data sharing platforms could enhance collaboration and accelerate progress in agriculture;
  • Technology of precision weeding;
  • Machine learning, robotics, sensor fusion and big data analytics.

As precision agriculture places higher demands on real-time field weed detection and recognition accuracy, this paper proposes a multi-scale information-enhanced weed detection algorithm, MIE-YOLO (Multi-scale Information Enhanced), for precision agriculture. Based on the popular YOLO12 (You Only Look Once 12) model, MIE-YOLO combines edge-aware multi-scale fusion with additive gated blocks and two-stage self-distillation to boost small-object and boundary detection while staying lightweight. First, the MS-EIS (Multi-Scale-Edge Information Select) architecture is designed to effectively aggregate and select edge and texture information at different scales to enhance fine-grained feature representation. Next, the Add-CGLU (Additive-Convolutional Gated Linear Unit) pyramid network is proposed, which enhances the representational power and information transfer efficiency of multi-scale features through additive fusion and gating mechanisms. Finally, the DEC (Detail-Enhanced Convolution) detection head is introduced to enhance detail and refine the localization of small objects and fuzzy boundaries. To further improve the model’s detection accuracy and generalization performance, the DS (Double Self-Knowledge Distillation) strategy is defined to perform double self-knowledge distillation within the entire network. Experimental results on the custom Weed dataset, which contains 9257 images of eight weed categories, show that MIE-YOLO improves the F1 score by 1.9% and the mAP by 2.0%. Furthermore, it reduces computational parameters by 29.9%, FLOPs by 6.9%, and model size by 17.0%, achieving a runtime speed of 66.2 FPS. MIE-YOLO improves weed detection performance while maintaining a certain level of inference efficiency, providing an effective technical path and engineering implementation reference for intelligent field inspection and precise weed control in precision agriculture.
