The present work describes the chemical characterization and the phytotoxicity assessment of essential oils (EOs) obtained from spent materials or pruning waste of four plant species: Roscoe used in the juicing industry, L. var. used in the food industry, discarded material of industrial hemp ( L. var. ), and pruning waste from L. The phytochemical profile of the EOs was evaluated by gas chromatographic flame ionization detection (GC-FID) and GC-MS analyses, which highlighted the presence of several compounds with a wide range of biological activities. Among them, application possibilities in agriculture were evaluated by studying the phytotoxic activity against germination and initial radical growth of several seeds such as L., L., L., L., Lam., and L.
