Bioherbicides, also known as nature-based herbicides, play a crucial role in sustainable agriculture by effectively inhibiting weed growth and development. They help increase crop productivity by reducing competition between plants for nutrients, water, and light. Their eco-friendly nature sets bioherbicides apart, promoting environmentally conscious farming practices. Despite their numerous benefits, many bioherbicide compounds are inherently unstable and susceptible to environmental degradation by temperature, light, humidity, and microbial activity, thus posing challenges for effective weed management. To address this issue, a growing emphasis has been placed on encapsulation strategies in recent years. Encapsulation techniques offer several advantages for bioherbicides, including enhanced efficacy, sustainable biological compound release, environmental factor protection, and shelf life improvement. Polymers, particularly biopolymers, are promising materials for bioherbicide encapsulation in micro-/nanoparticles. These particles are specifically designed for the targeted delivery of bioherbicides, ensuring effective crop protection and weed management. Micro-/nanotechnology incorporation in encapsulated formulation development has revealed their notable potential. This study focuses on the latest developments in the encapsulation of bioherbicides into micro-/nanoparticles and their practical application for weed management. By leveraging micro-/nanotechnology, researchers aim to maximize bioherbicidal application and efficacy, paving the way for sustainable agricultural weed management practices. The findings of this study may serve as a reference for expanding the use of micro-/nanotechnology-associated bioherbicides for providing potential sustainable weed control solutions.
