History of network

EU.NET.ICP: European network for development of anintegrated 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

Last 10 Workshops were sponsored by companies involvedin late and early blight

14

th

Workshop was held in Limassol, Cyprus in May 2013 15thWorkshop will be held in Brasov, Romania in May 2015

Organise a workshop every second year,

Max 100 participants

Next workshop is May 2015 in Romania

www.euroblight.net

1. Host resistance to P. infestans

2. Pathogen characteristics, population biology

and genetics

3. Epidemiology, integrated control and

decision support systems

4. Fungicides

5. Epidemiology and control ofAlternaria spp

The subgroups arrange the subgroup

meetings during the workshops, organize

harmonized protocols and co-ordinate and

integrate European research on each

topic.
