Special Issue Information

Dear Colleagues,

Bioherbicides are shedding new light on weed control in an economical and safe manner. The origins of most bioherbicides are living microorganisms including funguses, bacteria, and viruses (microbial herbicides) and naturally occurring products. So far, fifteen bioherbicides based on living microorganisms have been registered for use globally. However, only two are commercially available out of all registered bioherbicides. Such a status of microbial herbicides is due to their vulnerabilities that consist of narrow host range and low adaptability to slight fluctuations of environmental temperature and moisture conditions in the field. The exploration of natural products is another important approach of bioherbicide development. Approximately 200,000 secondary metabolites from plants and microorganisms have been identified. These natural products with high structural diversity and broad biological activity are considered to be an important resource for the development of new bioherbicides. However, there are also great challenges to efficiently discover target compounds with excellent herbicidal activity from huge amounts of natural products, as well as to clarify their mode of action and develop effective formulations. Advances in life and material sciences, especially the development of genetic engineering, genomics, proteomics, metabolomics, and nano techniques, will revolutionize these problems. Such research is helpful to understand pathogen–weed interactions and action mechanism of metabolites, improve virulence of pathogens and their adaptability to environmental variables, and develop good formulations and application methods. The aim of this Special Issue is to promote bioherbicide development through the publication of original research articles and reviews of research, theory, and technology.

Aquatic weeds, including invasive species, are a worldwide problem. The presence of aquatic weeds poses several critical issues, such as hindering the continuous flow of water in irrigation channels and preventing the proper distribution of adequate water quantities. Therefore, effective control measures are vital for agriculture and numerous downstream industries. Numerous methods for controlling aquatic weeds have emerged over time, with herbicide application being a widely used established method of weed management, although it imposes significant environmental risks. Therefore, it is important to explore nonchemical alternative methods to control existing and emerging aquatic weeds, potentially posing fewer environmental hazards compared with conventional chemical methods. In this review, we focus on nonchemical methods, encompassing mechanical, physical, biological, and other alternative approaches. We primarily evaluated the different nonchemical control methods discussed in this review based on two main criteria: (1) efficiency in alleviating aquatic weed problems in location-specified scenarios and (2) impacts on the environment, as well as potential health and safety risks. We compared the nonchemical treatments with the UV-C-radiation-mediated aquatic weed control method, which is considered a potential novel technique. Since there is limited published literature available on the application of UV-C radiation used exclusively for aquatic weed control, our review is based on previous reports of UV-C radiation used to successfully control terrestrial weeds and algal populations. In order to compare the mechanisms involved with nonchemical weed control methods, we reviewed respective pathways leading to plant cell death, plant growth inhibition, and diminishing reemergence to justify the potential use of UV-C treatment in aquatic habitats as a viable novel source for aquatic weed control.
