The mechanism of coumarin inhibits germination of ryegrass (Lolium perenne) and its application as coumarin–carbon dots nanocomposites

This study not only reveals the mechanism of coumarin on ryegrass germination, but also develop Cm-CDs nanocomposites to enhance the herbicidal activity of coumarin. Our findings will stimulate the application of Cm-CDs nanomaterials as an effective and environmentally friendly formulation in agriculture. © 2023 Society of Chemical Industry.
