Abstract :As the damage caused by weeds to agricultural crops increases, the use of herbicides is rapidly rising. The importance of allelopathy, one of the most environmentally friendly strategies in weed control, is growing day by day, making it one of the heavily researched topics in this field. Field bindweed (Convolvulus arvensis) is a weed causing considerable damage in agricultural areas. In this study, the in vitro allelopathic effect of field bindweed (C. arvensis) on weeds such as Sorghum halepense and Xanthium strumarium and on seed germination of crops such as cress (Lepidium sativum), cucumber (Cucumis sativus) and grass (Lolium perenne) was investigated. The studies were conducted in the Laboratory of Plant Protection, Faculty of Agriculture, Sakarya University of Applied Sciences in 2023. Water and methanol extracts derived from the green parts of field bindweed were applied to seeds in Petri dishes at concentrations of 1, 3, and 5%. According to the results obtained, it was observed that 5% methanol extract prevented seed germination in all plants. It was also concluded that 5% water extract prevented the germination (0% germination) of hogweed (X. strumarium) and cress (L. sativum) plants. Promising data were obtained from this laboratory study against the germination of various plant seeds of field ivy (C. arvensis), which is an agriculturally problematic plant, and the results will be further confirmed by conducting greenhouse and field trials.
