BACKGROUND Weed-resistance phenomena have increased dramatically in recent years. Bioherbicides can offer a sustainable alternative to chemical weed control but they often have low water solubility and therefore low efficacy in the field. The research reported here represents the first study on the field efficacy against weeds of a nanoencapsulated bioherbicide mimic of aminophenoxazinones, namely DiS-NH2 (2,2 '-disulphanediyldianiline). Field experiments were carried out across three different locations to evaluate the bioherbicide disulphide mimic at standard (T1, 0.75 g m(-2)) and double (T2, 1.5 g m(-2)) doses when compared to no weed control (NC) and chemical weed controlled (PC) in durum wheat. RESULTS The nanoencapsulated bioherbicide displayed better soil permeability than the free compound and also showed lower ecotoxicity on comparing the toxic doses on the Caenorhabditis elegans nematode model. It was found that T2 gave the best performance in terms of phytotoxicity (-57% weed biomass when compared with NC) and crop yield enhancement (3.2 versus 2.2 Mg ha(-1) grain yield), while T1 showed comparable results to PC. T1 and T2 did not cause shifts in weed communities and this is consistent with a broad spectrum of phytotoxicity. Moreover, the nanoparticle formulation tested in this study provided stable results across all three locations. CONCLUSION It is reported here for the first time that a nanoencapsulated DiS-NH2 bioherbicide mimic provided an efficient post-emergence and contact bioherbicide that can control a wide range of weed species in durum wheat without damaging the crop. The mimic also has low ecotoxicity and improved soil permeability. (c) 2025 The Author(s). Pest Management Science published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.

Herbicides are widely employed in agriculture to manage weeds and enhance crop yields, but their extensive use raises significant environmental and human health concerns. Exposure to herbicides can occur through multiple pathways, including ingesting contaminated food and water, inhaling airborne particles, and dermal contact during application. This review delves into the intricate dynamics of herbicide pollution in agriculture, examining their classification, modes of exposure, and impacts on plants, animals, and humans. This study also deals with the mechanisms by which herbicides contribute to adverse health outcomes, such as cellular damage and cancer. To address these risks, this review looks at more sustainable ways to manage weeds, focusing on practical and natural alternatives to chemical herbicides. These include traditional farming techniques, hands-on mechanical methods, and biological agents. Integrated weed management (IWM) is a holistic approach that combines these techniques to reduce herbicide resistance and environmental degradation. The natural alternative method is the use of bioherbicides, derived from live microorganisms or their metabolic byproducts known to stand out as eco-friendly and targeted solutions for weed control. This review emphasizes the need for sustainable practices to balance effective weed management and the preservation of environmental and human health. This paves the path for innovative and sustainable solutions to aquatic herbicide pollution through natural product-based interventions. This study emphasizes the importance of integrated techniques for achieving sustainable agriculture while minimizing environmental and health risks.
