Study of postemergence-directed herbicides for redroot pigweed (Amaranthus retroflexus L) control in winter wheat in southern Russia

Year: 2023

Type: article

Abstract: Redroot pigweed (Amaranthus retroflexus L). is a broadleaf weed in autumn crop fields in Russia.Four field experiments were performed in Stalskiy region, southern Russia in two growing seasons, 2016 and 2017, to investigate the effects of postemergence applications of applied alone or in tank mixtures in winter wheat cultivars Tanya and Bagrat.Redroot pigweed control was greatest with tribenuron and all herbicide treatments containing tribenuron.The lowest redroot pigweed control was with aminopyralid/florasulam (study 1) and triasulfuron (study 2), respectively, whereas redroot pigweed had intermediate responses to the other examined herbicides.Tribenuron plus fluroxypyr sprayed on wheat cultivar 'Tanya' , and tribenuron plus triasulfuron on wheat cultivar 'Bagrat' resulted in increased wheat grain yields.Overall, tribenuron and herbicides containing tribenuron provided the most efficient redroot pigweed control compared with the other herbicides and consistently maintained optimal winter wheat yields.Tribenuron could ameliorate redroot resistance to herbicides in wheat fields in southern Russia.
