The network combines two previous networks originating from European Concerted Actions and has 150 members. EU.NET.ICP: “European network for development of an integrated control strategy of potato late blight” (1996-2000). Coordinated by Huub Schepers. EUCABLIGHT: “A potato late blight network for Europe” (2003-2006). Coordinated by Alison Lees. The 14th Workshop was hosted by the Cyprus University of Technology in Limassol, Cyprus. The Workshop was attended by 94 persons from 16 European countries, Russia, Chile, Argentina, China and Israel. Representatives from all countries presented the late blight epidemic in 2012 and recent research results regarding integrated control, decision support systems, resistance of varieties, late blight in organic potatoes and population biology of the late blight pathogen. Since early blight is an increasing problem in Europe reports on this disease are also included. The papers and posters presented at the Workshop and discussions in the subgroups are published in these Proceedings, PPO-Special Report no. 16. The current and previous Proceedings are also available on the EuroBlight website www.EuroBlight.net. EuroBlight Coordinators: Alison Lees, The James Hutton Institute (UK) Jens G. Hansen, Aarhus University (DK) Huub Schepers, Wageningen University (NL) For further information please contact the network secretariat where also additional copies of this Proceedings can be ordered.
