Abstract: Mexico's main wine-producing region is located on the coast of Ensenada, Baja California, where favorable climatic conditions enable the production of 70% of Mexico’s highest-quality wines. The perennial weed field bindweed (Convolvulus arvensis L.) poses a significant threat for regional grape growers, due to its difficult control and its impact on production costs. One of the main strategies used to control field bindweed is the herbicide glyphosate, a broad-spectrum systemic agrochemical with harmful effects on human health and the environment. The objective of this study was to evaluate bioherbicides to determine as an alternative to glyphosate for controlling field bindweed in vineyards. Three commercial bioherbicides made from extracts of annual plants, pine resins, and the fungus Puccinia were tested, along with glyphosate as a control. The results showed that after 29 days of evaluation, only the HO3 bioherbicide was able to match glyphosate, achieving 83% control compared to glyphosate's 87%. It was also observed that the three bioherbicides had similar effects on the fresh and dry weight of bindweed rhizomes as those achieved with glyphosate.
