International Council of Grapevine Trunk Diseases (ICGTD)
The International Council of Grapevine Trunk Diseases has been welcomed as a Subject Matter Committee of ISPP (see ISPP Newsletter 31 (4) August 2001).
In recent years trunk disease problems have emerged that are of paramount importance to the grape industry. They include the resurgence of esca (black measles) and Eutypa dieback in mature vineyards, dieback by Botryosphaeria species and decline diseases of young vines in newly planted vineyards. These diseases were attracting attention from scientists all over the world, but the research was often conducted in isolation and there was little exchange of the rather fragmentary information.
The realization that both esca in mature vines and decline in young vines were associated with the same fungus, and the naming of that fungus as Phaeoacremonium chlamydosporum (later renamed Phaeomoniella chlamydospora) focussed the attention of researchers on possible inter-relationships of these diseases. The need for closer coordination between scientists working on these diseases was realized, and the idea of an International Council on Grapevine Trunk Diseases was conceived.
The first Council meeting took place in California (USA) in July 1998, and agreed on objectives and a structure for the Council. The Council serves as a forum for researchers from grape growing countries.
The Council executive consists of a chairperson and four regional coordinators. The first Chairperson of ICGTD was Dr. Luigi Chiarappa, who first proposed the formation of a Council. The other Founding Members were Ian Pascoe, Lucie Morton, Laura Mugnai, Lisa van de Water, and Philippe Larignon.
The International Council of Grapevine Trunk Diseases has been welcomed as the Subject Matter Committee on Grapevine Trunk Diseases by the International Society for Plant Pathology (see ISPP Newsletter 31 (4) August 2001).
The Committee has organized 5 International Workshops:
1st IWGTD, Siena, Italy (October 1999);
2nd IWGTD, Lisbon, Portugal (September 2001);
3rd IWGTD, Christchurch, New Zealand (February 2003),
4th IWGTD, Stellenbosh, South Africa (January 2005),
5th IWGTD, Davis, California (2006)
The 6th IWGTD will be held in Firenze, Italy, next 1-3 September 2008
Two Special issues and 3 issues containing peerly reviewed papers with the more relevant results obtained on the subject that had been presented by selected experts at the five workshops were published in Phytopathologia Mediterranea.
The ICGTD is a non-profit organisation. It has no sponsors, no membership fees. All its activities are carried out on a volunteer base, and with the strong support of ISPP and of MPU (Mediterranean Phytopathological Society, editor of Phytopathologia Mediterranea).
A website for the Council or ISPP Committee activities is now under preparation (htpp://icgtd.org/ (working but still under construction) with the help of the UC Davis Department of Plant Pathology, California (USA).
The ICGTD, meeting so often, managed to create a close net of communication and collaboration. Students and researchers moved from one research centre to the other for collaboration in research and for exchange of information. The frequent and most friendly contacts created a really fruitful and pleasant friendly atmosphere in the group. In this atmosphere ICGTD Workshops also become an occasion for discussion and decision making on general matters as names of the trunk diseases we are dealing with.

The Executive ICGTD Council is composed by founding members, chairperson, regional coordinators, previous workshop organizers and honorary members. The Council agreed to designate as chairperson of the IWGTD the person in charge of the organization of the last International Workshop on Grapevine Trunk Diseases. Thus, in June 2012, Josep Armengol, who organized the 8th IWGTD, was designated as the Chairperson of the ICGTD until the next International Workshop, that will take place in Adelaide, Australia (November, 2014). http://www.plevin.com.au/iwgtd2014/
The ICGTD Council manages a wide members mailing list (280 addresses) which includes all participants to the 8 workshops.
The Committee has organized 8 International Workshops:
The 9th IWGTD will be held in
The ICGTD, organizes an International Workshop on Grapevine Trunk Diseases (IWGTD) each two years. This is a good opportunity to create a close net of communication and collaboration among researchers dealing with this topic worldwide, aiming to exchange of information and decision making on general matters on the trunk diseases we are dealing with.
Subject Matter Committee focus issues:
The ICGTD focuses on Grapevine fungal trunk diseases, which causal agents are located in the mature stem (trunk and cordons) of grapevines. These diseases include esca (black measles), Eutypa dieback and dieback caused by Botryosphaeriaceous species in mature vineyards, and decline diseases of young vines in newly planted vineyards. Related trunk diseases caused by other fungal pathogens such as Campylocarpon, Cylindrocladiella, Ilyonectria, and Phomopsis, are also included.
