Van Vliet succeeds Marius Varekamp as part of a series of moves on the Horti Fair board as the event seeks to reposition itself to better promote international horticulture to the world.
The shake up includes five new board appointments to join three members who have agreed to stay in post.
Departing chairman Varekamp said: "The new board provides the required combination of entrepreneurship and organizational experience. In addition, the reorientation of the Horti Fair made it clear that the bond with horticulture has to be made stronger in administrative terms as well. Both these goals have now been achieved
Plans for the event will be announced at this year’s show, due to be held at the Amsterdam RAI from 12-15 October.
The event will be jointly organised with FloraHolland Trade Fair and is expected to debut in November 2011.
Van Vliet added: "The Horti Fair is in favour of bundling the range available at trade fairs and against fragmentation."
Appointments include Avag chairman Harm Maters, Visser International managing director Cees Visser, Horticoop managing director Igo Janssen, Hendriks-Agro cultivation managing director Frank Hendriks and Ki Plants trade director Sander Kroll.
