Abstract Viticulture generates significant pruning wastes, which can be valorized as bioherbicides for sustainable weed management, and a means to advance the circular economy. Allelopathy, an environmentally friendly approach in plants release secondary metabolites that suppress growth of other species, presents managing agricultural systems. Our study aimed assess whether biotic (grapevine variety mycorrhization) abiotic (atmospheric CO2 level, air temperature or water availability) factors influence accumulation grapevine (Vitis vinifera L.) wastes their allelopathic effects on three cosmopolitan weeds (Sisymbrium irio, Solanum nigrum Sonchus oleraceus). Two varieties, Tempranillo Cabernet Sauvignon, inoculated (M) not (NM) with mycorrhizal fungi, were grown under two environmental conditions: CATA (current conditions i.e., 400 ppm ambient temperature) CETE (700 + 4˚C). Within each condition, half M NM subjected either full irrigation (WW) (90–100% substrate field capacity, FC) limited (D) (cycles from 90–100% 20–30% FC). Characterization methanolic extracts revealed variations phenolics, flavonoids, flavonols, anthocyanins across treatments, higher free radical scavenging activity elevated CO₂ conditions. variety, compounds was also influenced by level presence absence root-associated fungi. Aqueous leaves used germination bioassays strongly inhibited seed seedling weeds, pronounced observed S. irio. The these contributes effect, highlighting potential waste alternative synthetic herbicides. However, further studies are needed determine optimal extract concentrations crops
