20.500.12556/DKUM-91667 Long-term control of hedge bindweed (Calystegia sepium L.) with single, tank mixture, and sequential applications of glyphosate, 2,4-D, and dicamba Hedge bindweed (Calystegia sepium L.) is a widespread troublesome perennial weed species that has strong rhizome regenerative capacity. Four pot trials with randomised, complete block designs were conducted in 2015 to evaluate long-term control of hedge bindweed using individual, tank mixture, and sequential applications of selected herbicides. Two different formulations of N-(phosphonomethyl) glycine (glyphosate; isopropylamine, trimesium salts) were applied at 2000 g active ingredient (a.i.) ha−1. Additionally, two synthetic auxins were applied as 3,6-dichloro-2-methoxybenzoic acid (dicamba) at 500 g a.i. ha−1 and the dimethylamine salt of (2,4 dichlorophenoxy)acetic acid (2,4-D) at 1000 g a.i. ha−1. Tank mixtures and sequential applications (12/24 h separation) of these different herbicides were also included. Long-term control of hedge bindweed, Calystegia sepium L., growth was evaluated 8 months after treatments, as comparisons of shoot and rhizome growth (biomass) between untreated and treated plants. There were no differences between the two formulations of glyphosate alone, with shoot and rhizome biomass reductions of 83% and 42%, respectively. Dicamba alone inhibited shoot and rhizome biomass by 86% and 67%, respectively. By itself, 2,4-D provided the greatest reductions in shoot and rhizome biomasses, 93% and 79%, respectively. Antagonism was seen in the tank mixtures of glyphosate and dicamba or 2,4-D. Tank mixtures were generally comparable to treatments of glyphosate alone, and were less effective compared to dicamba or 2,4-D alone. The greatest reduction of bindweed rhizome biomass was for sequential glyphosate trimesium salt followed by 2,4-D 12 h later, thus showing significantly greater efficacy over glyphosate isopropylamine salt (94% vs. 84%; p ≤ 0.05). These data for reductions of the growth of the rhizome biomass show that the sequential application of glyphosate followed by 2,4-D significantly improves long-term control of hedge bindweed. hedge bindweed perennial weeds rhizome control weed management herbicide efficacy plotni slak večletni pleveli zatiranje rizomov zatiranje plevelov učinkovitost herbicidov Calystegia sepium L. true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2025-01-24 14:37:46 2025-01-24 14:45:34 2025-01-25 03:11:17 0000-00-00 00:00:00 2020 0 0 Str. 1-15 št. 8, št. članka 1184 Letn. 10 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-07-20 2020-08-10 2020-08-13 632 25332483 10.3390/agronomy10081184 2073-4395 Kolmanic-2020-Long-Term_Control_of_Hedge_Bindw.pdf Kolmanic-2020-Long-Term_Control_of_Hedge_Bindw.pdf 1 9D9C63B967AC89C81FD62BE728CD959A f6214fb8f58633fdd8d28126a0fdbf1e1968a4ace5aaec1ea5aac9e674fc7934 538da082-da59-11ef-9445-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188131 https://doi.org/10.3390/agronomy10081184 0 5d95dd75-da59-11ef-9445-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188132 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
