We kindly remind all participants that the deadline for submitting the papers for the St Petersburg Proceedings is 15 February, 2012

Please find the new updated EuroBlight report: Fungicide evaluation to rate efficacy to control leaf late blight for the Euroblight table Results 2006 + 2010 at the buttom of this main page

Summary and full text of the statements from the St Petersburg Workshop is now available

Please find the the Provisional ratings for the effectiveness of new fungicide products for the control of P. infestans in Europe, B table, and, the Efficacy ratings of fungicides for the control of early blight caused by Alternaria solani and Alternaria alternata under Fungicide comparison and then via links to pdf versions below the table.

The 13th EuroBlight Workshop, 9-12 October 2011 is hosted by N.I. Vavilov Research Institute of Plant Industry, St Petersburg, Russia. The Workshop will be attended by 91 persons from 20 European countries, Russia, Israel, Chile, Argentine and United States of America. Representatives from all countries will present information on the late blight epidemic in 2010 and 2011and recent research results regarding integrated control, decision support systems, resistance of varieties and population biology of the late blight pathogen in potatoes. 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 will be published in the Proceedings, PPO-Special Report no. 15. The current and previous Proceedings are also available on the EuroBlight website www.EuroBlight.net.

1. For the participants who want to arrive earlier and depart later to St. Petersburg Park Inn Pulkovskaya hotel offers special room rates from the 5th to 21st of October.
2. Every participant chooses dates of staying individually when booking accommodation on-line.
3. Tourist visa support documents are issued by Park Inn Pulkovskaya hotel according to the hotel booking dates indicated by a participant.

Information from surveillance systems on late blight from the Nordic countries, the Netherlands, Germany and UK (see links in lower right box) show that a few (1-2 per country) primary attacks were recorded in early June in covered or very early planted potatoes. In Dk, only two early attacks show indications of oospores. After the dry spell in most of June wide-spread attacks are now (5-13 July) recorded in most regions due to shift in weather conditions. This pattern should be a warning about increasing infection pressure.

The relatively cold May delayed crop growth with 10-14 days in many regions and weather conditions in June was unfavorable for disease development

The season in 2010 show the potential of using effective decision support systems as the delay of epidemic developments of approximately one month (date calendar) saves 3-4 fungicide applications in the beginning of the season.

It is already 2 months ago since we met during the EuroBlight Workshop in Arras. Manuscripts of oral presentations or posters can be submitted until 1 September 2010. To reduce the editing process we ask you to submit a Word document inwhich the tables, figures and photos are already included.

After 1 August we start to upload the articles received as seperate papers in the list of presentations to be found via link in lower left box on this page

When you presented a poster, it is possible to submit a manuscript or a PDF of the poster. Please let us know which option you prefer.

Please find the draft scientific program for the Arras Workshop here

Please find the updated list of people registered for Arras here

Today we e-mailed all people that have registered to the Arras workshop, to confirm their registration via the registration web form.

If you have not received this mail, and you suppose that you have registered, your registration was not stored and you have to register again.

We have had problems with two different mail servers, but we expect the all problems are solved now. We excuse the problems this has caused for a few of you.

The fungicide comparison table was updated on 15 January 2010 with new data regarding leaf blight. The new scores are based on the results in the report: Fungicide evaluation to rate efficacy to control leaf late blight for the Euroblight table - Results 2006 - 2009, available from this site.

New results on foliage blight resistance was uploaded today - one trial from Poland and one trial from Scotland. On Eucablight select Host and then the Show button for each trial

Please find the 2nd announcement of the EuroBlight workshop in Arras, France 3-6 May 2010 here

• Under The menu item "Decision support" you will find the "Comparison of submodels" platform aiming at analysing and comparing different weather based submodels for the risk of infection, disease development, fungicide degradation etc.
• Each submodel is described under the menu item "Submodels description".
• The weather data used, locations and years included are explained under the menu item "Weather data."
• Several of the submodels are important drivers of whole DSSs for the control of potato late blight. A list of those systems are available under "DSS systrems overview.
• The best practice for the control of late blight as indentified in the ENDURE potato case study is described under the "Best practice" menu item.

Local organisers: Serge Duvauchelle, Ludovic,Dubois, Roselyne Corbiere, Catherine Chatot, Marie-Pascale Latorse and Didier Andrivon.

Late blight is only slowly developing in the UK, the Netherlands and in the Nordic countries. In Norway and Finland only one attack is recorded in each country and both are in plastic covered potatoes. In Denmark only one attack is recorded - in a field experiment. This attack is supposed to be from oospores. In the Uk attacks are only found in Cornwall, In the Netherlands a handful of fields in the starch potato regionin the NothEast of the country were infected.

You can follow the disease progress for the Nordic region on Euroblight (Select Pathogens/Monitoring. Click on the icons to see background information) and the situation in The Netherlands from Dacom, Phytophthora Masterplan and from the UK at BPC, Fight Against Blight

During the forthcoming days Euroblight will be upgraded to a more modern web and database platform similar to Eurowheat. Eurowheat and Euroblight will share database and applications. The first new application compared to the previous platform will be a new monitoring system to replace Web-Blight. Initially this will be a tool aiming at monitoring early attacks of potato late blight in the four Nordic countries, but it can easily be expanded to include any country in the world.

More new features and applications will be implemented during the next months

The protocol: "Harmonised protocol for testing fungicides for effectiveness against tuber blight" has been updated. Responsible: Ruairidh Bain

Next workshop is planed for May 2010 in France. If you know any important meetings or conferences on similar issues planned for May 2010, please inform us about it.

We wish you all a merry christmas and a happy new year

The Fungicide comparison table was updated today. Update since 2007: Ratings for mandipropamid is now included in the table. Ratings for leaf blight is based on results from Euroblight field trials during 2006-2008, and only compounds included in these trials are rated for leaf blight. The scale for leaf blight is a 2-5 scale (see technical report under Results/Public Documents). All other ratings are 1-3 scale indicated by a combination of full (1) and half (½) orange colored dots.

Update on fungicide efficacy on leaf blight control was updated at the Hamar workshop 28 - 31 October 2008. The updated table on leaf blight control is available under the menu item "Update leaf blight control, Hamar". The Fungicide comparison table will be updated when the Euroblight technical group has decided how to implement the decimal figures used only for leaf blight.

The deadline for registration to the Hamar workshop was exceeded on 15 August. The maximum number of participants - 70 - was exceeded, and right now we can not guarantee that all people registered can participate. All people who have registered with a valid e-mail address will be announced about their participitation within two weeks. After this announcement, we start working on the detailed programme via e-mail. The final programme will be announced as soon as possible, but not later than 1 October

The next Euroblight workshop is scheduled to 28-31 October, 2008 in Hamar, Norway. The local organiser is Arne Hermansen, BioForsk. Further information and deadlines for registration will follow soon.

Recently we implemented a protocol section under the Results menu. This section combines the original Eucablight protocols and new protocols related to test of fungicides.

Links to the Eucablight databases on host resistance and pathogen characteristics are now available in the Databases Menu box.
