Cocklebur (Xanthium strumarium L.), creeping thistle (Cirsium arvense ( L.) Scop.), false carrot (Turgenia latifolia (L.) Hoffin.), field bindweed (Convolvulus arvensis L.), prostrate sandmat (Euphorbia prostrata Aiton) and wild mustard (Sinapis arvensis L.) as broad-leaved and bermudagrass (Cynodon dactylon (L.) Pers.), canarygrass (Phalaris paradoxa L.), common oat (Avena sativa L.), green foxtail (Setaria verticillata L.), johnsongrass (Sorghum halepense (L.) Pers.) as grass were identified as the 10 most common weeds. Weed density (plant m(-2)) was determined in applications with the lowest with soil herbicides (indaziflam + mechanical 3, indaziflam + fluazifop-P-butyl 4, and indaziflam 5), also after weedy check (59), it was detected the most in the mechanical (23). Weed control efficiency (WCE, %) was the highest with soil herbicide (indaziflam + mechanical 95, indaziflam + fluazifop-P-butyl 92, and indaziflam 90), also it was the lowest in the mechanical (62). Grape yield (kg plant(-1)) was the highest with soil herbicide (indaziflam + mechanical 3.75, indaziflam + fluazifop-P-butyl 3.64, and indaziflam 3.57), also it was the least in the mechanical (2.73). It was determined that grape yield decreased up to 32% depending on weeds, density and managements. Weed control is one of the important agricultural practices that should be applied in the management of vineyards as it prevents loss of yield by preserving soil moisture and reducing competition for essential mineral nutrients required for grapevines.eninfo:eu-repo/semantics/closedAccessGrapevineVineyardViticultureMechanical weed managementPre emergence herbicidesArticle292766772Q4WOS:000514253400012
