Aryl sulfoxide scaffold useful as herbicide

Abstract

The escalating demand for effective and sustainable weed management strategies, driven by urbanization expansion, is a critical challenge. Herbicides are pivotal tools in modern agriculture, addressing this challenge. Developing novel herbicides with enhanced efficacy and minimal environmental impact is crucial for food security and ecological balance. While numerous herbicides have been developed with varying availability over time and regions, there's a continuous need for innovation. In this study, we explored relatively understudied sulfoxide-containing herbicides and synthesized a smaller yet substantial sulfoxide scaffold for herbicide development. Through screening Digitaria ciliaris (Retz.) Koeler, Amaranthus lividus L., and Solanum nigrum L., we observed promising herbicidal efficacy, especially against Wild Amaranth. Encouraged by preliminary findings, we recognize the potential for refining the core structure. In summary, we fashioned a structurally simple sulfoxide scaffold showcasing discernible herbicidal impact on broadleaf weeds.
