Effective combination of management methods suppresses invasive Jerusalem artichoke

Abstract The main intention of our research is to determine an effective method to suppress invasive plant populations of Helianthus tuberosus spreading uncontrollably in the territory of the Poodří Protected Landscape Area (PLA) in the Czech Republic. This article brings together the results of selected management methods from 2017-2019 (mechanical, chemical and their combination) and their effect on the growth and reproductive characteristics of Helianthus tuberosus as well as the biodiversity of the local habitats. The combination of mowing and application herbicide based on clopyralid, fluroxypyr and MCPA proves to be the most effective. The partial results have been published before [1,2]. We present a complete research overview of the Helianthus tuberosus disposal.

Field experiments were conducted over a 3-yr period to evaluate the efficacy of herbicides for the control of volunteer Jerusalem artichoke [Helianthus tuberosus (L.) # HELTU] in barley (Hordeum vulgare L.) and on summer fallow. In barley, Jerusalem artichoke was controlled with a single postemergence application of clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) at 1 kg ae/ha, or at 0.5 kg/ha when combined with 2,4-D [(2,4-dichlorophenoxy)acetic acid] at 0.5 kg ae/ha. Dicamba (3,6-dichloro-2-methoxybenzoic acid) at 0.2 kg ae/ha plus 2,4-D at 0.4 kg/ha was also an effective combination. Split applications of 2,4-D at 0.4 kg/ha each were more effective than a single treatment at 0.8 kg/ha. On summer fallow, glyphosate [N-(phosphonomethyl)glycine] applied at 0.5 to 2 kg ai/ha, as a single or repeated treatment, provided only marginal control of Jerusalem artichoke during the season of treatment and, in one of three experiments, reduced regrowth in the year following treatment.
