Chemical and mechanical methods for suppression of Jerusalem artichoke (Helianthus tuberosus L.)

Jerusalem artichoke (Helianthus tuberosus L.) is considered as a weed of natural conservation areas, but it can occur on arable lands and ruderals, also. The aim of our study was to investigate the efficiency of some chemical and mechanical treatments in small plot experiments under field conditions. Experiments were set up on the south-west part of Hungary (Somogy County), heavily infested with H. tuberosus. The stands were mowed before chemical treatments and the plant residues were left on the field.
