9th Workshop of International Legume Root Disease

Satellite meeting of the ILS on Monday, September 18th

We are pleased to announce that the 9th ILRD workshop will be held as a satellite meeting of the ILS4 on Monday September 18th, in Granada Spain. The meeting is being jointly organized by Agriculture and Agri-Food Canada – Lethbridge Research and Development Centre; and the Crop Development Centre, University of Saskatchewan.

Root diseases are economically important in legumes, affecting large areas of crop production in many countries worldwide. Root rots, caused by Aphanomyces euteiches, Rhizoctonia solani, Fusarium species and wilts, caused by several formae speciales of Fusarium oxysporum, Pythium and Phytophthora species are the most destructive soil-borne diseases of cultivated legumes such as pea, chickpea, lentil, soybean, bean, faba bean, lupin and alfalfa.


The objectives of the workshop will be to:

• Report recent advances of science on root diseases of legumes

• Gather the research community and stimulate networking


The scientific program will include sessions about:

• Survey, occurrence and epidemiology

• Pathogen biology, population genetics & genomics

• Plant-pathogen and pathogen-soil micro-organism interactions

• Plant genetics, genomics and breeding for resistance

• Integrated disease management


The International Legume Root Disease workshops were launched in 2002 in Rennes, France, by the initiative of scientists and professionals from France and the USA. They aim to promote the international dissemination and discussion of the most recent research results and achievements of the science on legume root diseases. Their objective is to support communication and collaboration in the scientific community and help breeders, plant pathologists and industry stakeholders with the identification of research gaps, priorities and applications.

• 2002 Rennes, France

• 2003 Pasco, WA, USA

• 2007 Rennes, France

• 2009 Pullman, WA, USA
