Effective combination of management methods suppresses invasive Jerusalem artichoke.
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.
