Dear Colleagues, I wish all of you a happy and successful year 2010 with many excellent ideas and of course enough money to make them work! This is my first Presidential Message to you. It is a great honour for me to take over from a successful and highly appreciated EWRS president, Per Kudsk. Let me thank him first for his outstanding service and for all the activities he initiated during the past two years. Per thinks outside the box. He is an ambassador for the biodiversity topic without forgetting the control of problem weeds and invasive species. Cooperation with him is convenient and pleasant. I am happy to share my views with him and to get advice from him as Past President. I would like to remind you that we have a new vice president, Paolo Bàrberi. He has served the EWRS as scientific secretary for eight years. Also, we have a new scientific secretary, Josef Soukup. I had the pleasure to prepare a meeting with him on Weed Mapping last year. He will be a valuable member of our new team. All in all, EWRS has a new functioning board. Let me assure you that we will try to keep the high standard of our predecessors. What about the status of our society? Our society is flourishing. We have more than 530 members and I am convinced we don’t have a demographic problem. Our working groups are right at the edge of weed science, they are international and multidisciplinary. The magazine “Weed Research” has a high reputation and a relatively high impact factor. Our Newsletter is a modern forum for our members allowing everybody to contribute. So, what’s new and special? We see arising problems with a changing weed flora in arable and non-arable land. Global warming and international trade seem to contribute to the spreading of invasive weeds in Europe. These weeds have a negative influence on the endemic flora and on biodiversity. Senecio jacobaea, Senecio inaequidens, Heracleum mantegazzianum, Impatiens grandiflora and especially Ambrosia artemisiifolia are not only aggressive; but the toxic principles of Senecio species seem to become a serious threat in the food chain also. Some of us suffer from the allergenic potential of Ambrosia and Heracleum. Wildfires are a result of invasive plants in Southern California as Carl Bell from San Diego lined out in his presentation at our Santorini conference on “Novel and sustainable weed management in arid and semi-arid agro-ecosystems”. I wonder if weeds contribute to Mediterranean wildfires in Europe as well. SciCom has decided to establish a new official Weed Mapping Working Group within the EWRS. Eastern European countries had a long tradition of weed surveys. The data are there but many of them are not published in English. Hohenheim University has provided server capacity for the storage and exchange of weed mapping data. Hungary, the Czech Republic and Finland have started with new mapping campaigns. We are eager to see the results as soon as possible. Chemical companies are reducing their classical chemical research. Many agricultural crops in the Americas and in Asia are based on biotechnology, i.e. the probability for new modes of actions controlling resistant weeds is decreasing. Glyphosate resistance has been reported now for Europe as well. Mechanical weed control tools are becoming less attractive due to high energy prices, due to CO2

reduction targets and due to the awareness of erosion prevention. Farmers are facing low commodity prices and cannot afford expensive weed control tools any more. These are just a few items. You see, there are still countless problems to be solved. I am looking forward to the EWRS symposium in Kaposvar. More than 330 abstracts have been submitted within the last months. I encourage you to attend this wonderful opportunity and to exchange the latest scientific news in an interesting surrounding. I especially thank Gabriella Kazinczi and the organizing committee for their efforts and for their great achievements. Now let me wish you all the best for the coming season again. Hansjörg Krähmer

CHAIRPERSON: Hansjörg Krähmer. PRESENT: Paolo Bàrberi, Lammert Bastiaans, Christian Bohren, Bärbel Gerowitt, Paul Hatcher, Per Kudsk, Baruch Rubin, Francesco Tei, Maurizio Vurro. INVITED: Gabriela Kazinczi, Nandor Matrai. EXCUSED: Svend Christensen, Bo Melander, Ilse Rasmussen, Jens Streibig, Anne Thompson. 50.1 Opening The minutes of the 49th SciCom meeting, Osijek (HR), 13 September 2008 were approved. No short communications. 50.2 15th EWRS Symposium, Kaposvár (HU), 11-15 July 2010 Scientific Programme G. Kazinczi suggested to contact Prof. Robert Novak, a Hungarian professor expert in weed community dynamics, and ask him if he is available to give the plenary introductory lecture. SciCom asked her to act accordingly and promptly refer about the outcome. It was decided that each session will have a short introduction to the themes of oral and poster papers included. P. Bàrberi proposed a tentative programme with subdivision into sessions and provisional allocation of papers to them. After a long participated discussion, SciCom decided to structure the scientific programme into the following seven sessions, each with two organisers:

• Chemical weed management (chair: Per Kudsk & Jens Streibig). • Herbicide resistance (chair: Baruch Rubin & Anne Thompson). • Invasive plants and biocontrol (chair: Christian Bohren & Paul Hatcher). • Non chemical tactics and strategies (chair: Bo Melander & Svend Christensen). • Weed biology (chair: Kirsten Tørresen & Maurizio Vurro). • Weed diversity in time and space (chair: Bärbel Gerowitt & Hansjörg Krähmer). • Weed ecology (chair: Lammert Bastiaans & Francesco Tei).

Budget Nandor Matrai from Asszisztencia Congress Bureau illustrated his proposal as symposium fee. After a long discussion, SciCom agreed on the following fees: • Student fee: 250*/300** € • Members fee: 350*/420** € • Non members fee: 450*/540** € *Before 31 March 2010. **From 1 April 2010. It will be compulsory to have one person registered by 31 March 2010 to have the abstract published in the Proceedings. Members fee is available to anyone who renew membership or become new member by 31 March 2010. Nandor’s presentation also covered the registration procedure, the sponsorship plan (state of the art and prospects), advertisements and stands, administrative issues, the venue, hotels and transportations, the Symposium excursion and other social events. SciCom is happy on how things are organised so far and congratulated LoCom.

Miscellanea The EWRS decided to allocate 10,000 € as subsidy to young research fellows presenting a paper at the Symposium. This amount is meant to be flexible, i.e. it can increase of a few thousand Euro should a considerable amount of applications be submitted. The deadline for applying is set at 15 January 2010. The Proceedings and printed programme will be available at the Symposium in the delegate’s folder. The IWSS Board will meet in Kaposvar during the Symposium (exact date and time to be decided). Per Kudsk has been nominated head of the Scientific Programme Committee for the 6th International Weed Congress scheduled for 2012 in The Popular Republic of China. During the 15th EWRS Symposium, SciCom and the Board will have an informal meeting with all the subsidised students. The three best posters (upon judgement of an ad hoc EWRS Committee) will receive an award. The EWRS Board will also meet with the National Representatives. Per Kudsk (with the help of Hansjörg Krähmer and Bärbel Gerowitt) will organise this last meeting in the coming months. Next deadlines

• 20 November 2009: detailed session programme (session organisers to P. Bàrberi) • 25 November 2009: detailed overall programme (P. Bàrberi to LoCom). P. Bàrberi will decide the

sequence of sessions based on a rotational concept with the sequence chosen for the latest three symposia.

• 30 November 2009: communication of paper acceptance/rejection, allocation to session and names/contact details of session organisers (LoCom to authors).

• 15 January 2010: submission of abstracts (authors to session organisers via the Symposium website). Submission of applications for junior scientists subsidy (to P. Bàrberi). Release of 2nd circular, including detailed programme (LoCom).

• 15 January-1 March 2010: paper revision process (session organisers). • 15 March 2010: electronic submission of final version of one-page text abstracts (authors to

session organisers). Communication of results of the junior scientists subsidy call to the awardees (J. Soukup, new EWRS Scientific Secretary).

• 31 March 2010: delivery of final version of abstracts for Book of Abstracts (session organisers to LoCom) and deadline for early bird registration (at reduced cost). Authors (at least one per paper) not registering by that date will have their paper deleted from the Book of Abstract. Registration (at standard cost) will be possible from 1 April 2010 to the symposium date but without publication of abstracts.

• 11-16 July 2010: 15th EWRS Symposium at Kaposvár (HU). On 11 July 2010 the WG Education and Traning will organise a workshop on “How to write a weed paper for a scientific journal”. The workshop will be free for EWRS members but will have a limited number of attendees (decided on a first come-first served criterion). The teachers will be Jon Marshall (Editor-in-Chief of Weed Research) and Jens C. Streibig (Professor, University of Copenhagen, DK). This workshop will be part of the official Symposium programme.

50.3 16th EWRS Symposium, 2013 A call for bids for hosting the 16th EWRS Symposium in 2013 will be launched through the EWRS Newsletter and website (deadline: 15 January 2010). Members willing to make a bid will be asked to produce a dossier with detailed information on the venue, transportation and accommodation facilities, availability of EWRS members to constitute a LoCom, requirements for visa and health insurance, etc. 50.4 3rd International Symposium "Intractable Weeds and Plant Invaders", Ascona (CH), 2-7 October 2011 C. Bohren presented the event and the first news. ETH-WSL will host the meeting in their facilities at Monte Verità (Canton Ticino). The objective of the event (co-organised by the WG Invasive Plants) will be to meet science with practice.

50.5 11th World Congress on Parasitic Plants, Bari (Italy), 7-12 June 2011 M. Vurro presented the event and the first news. The Congress will be co-organised with the International Parasitic Plant Society (IPPS) and will include a session on parasitic weeds in Europe organised by the WG Parasitic Weeds. 50.6 New WG on European Weed Mapping H. Krähmer presented the the idea and first activities, mainly stemming from a dedicated meeting held in Prague in May 2009. A further ambition of the WG will be to extend beyond Europe and map the world. Maps from Brazil and the USA are already available. One of the most important actions would be to harmonise data acquisition protocols. One of the main objectives is to predict weed shifts. Emphasis will be on frequencies, not distribution, but geobotanists could be involved. The University of Hohenheim will provide a freely accessible server with data from the whole Europe. However, data on herbicide resistant weeds cannot be made public for privacy reasons. SciCom unanimously approved the establishment of this new WG. 50.7 Working Group activities WGs presented a synthesis of their recent and foreseeable activities as well as the 2009-10 reports and requests for additional budget to the Board:

• WG Biological Control of Weeds: he will collaborate with the WG Invasive Plants for the organisation of the Délemont event. There is potential collaboration with the Ambrosia people. No extra budget required.

• WG Crop-Weed Interactions: no extra budget required. • WG Education and Training: +1000 € required. • WG European Weed Mapping: no extra budget required. • WG Germination and Early Growth: the multi-site joint experiment that has been carried out in

the latest years will soon generate a joint paper to be submitted to Weed Research. No extra budget required.

• WG Herbicide Resistance: P. Kudsk pointed out the need to revitalise this WG and clarify its position with HRAC. As such, H. Krähmer (with the support of B. Rubin and P. Kudsk) will contact A. Thompson. No extra budget required.

• WG Invasive Plants: the Jvaskyla symposium (August 2009) was attended by ca. 105 delegates. Five young scientists were subsidised. There was a proposal to organise the next symposium on aquatic weeds in Poland in 2012. On 6-7 December 2009 the WG will have a meeting on Ambrosia artemisiifolia in Délemont (CH) in conjunction with the 1st meeting of the newly born International Ragweed Society (IRS). + 3000 € required.

• WG Optimisation of Herbicide Dose: in 2009 they repeated a multiple-site joint experiment, from which they plan to publish a joint paper. No extra budget required.

• WG Parasitic Weeds: in 2009 the WG has organised an OECD conference in Ostuni and has contributed to the organisation of the 10th World Congress on Parasitic Plants in Turkey (June 2009). No extra budget required.

• WG Physical and Cultural Weed Control: +1000 € required. • WG Site-specific Weed Management: this WG has been dormant for the last couple of years.

SciCom expressed concern on the status of this WG. P. Kudsk will contact S. Christensen to investigate possible actions to revitalise the WG.

• WG Weed Management Systems in Arid and Semi-arid Environments: a conference was organised in Santorini (GR), September 2009. Ten students were supported. A tentative idea is to have the next conference in 2011, possibly in Italy or Spain upon collaboration with the WG Weed Management Systems in Vegetables. Carlos Zaragoza proposed to initiate a course on Weed Management in arid and semi-arid environments at CIHEAM-IAMZ, possibly with the support of EWRS. P. Bàrberi asked B. Rubin to clarify this point and recommended to involve the WG Education & Training. No extra budget required.


7

• WG Weed Management Systems in Vegetables: after many new years Francesco Tei is willing to step back from coordination of the WG. He made an inquiry among the WG members but no one volunteered to take on this task except Euro Pannacci from his same University (Perugia, IT). Euro will be supported by Francesco during the transition phase and will be introduced by him to SciCom at the next meeting in Hungary. SciCom warmly thanked Francesco for his long-lasting commitment to EWRS activities and welcomed Euro. No extra budget required.

• WG Weeds & Biodiversity: the latest workshop, organised in Lleida (ES), was attended by 82 delegates (>50% of which were PhD students) and turned out to be very interactive. The next workshop will be held in France in 2011 (place and date to be finalised). Two methodological subgroups, on GIS mapping and on methodologies in seed predation, will be established. There are good possibilities to interact with The WG Education and Training. No extra budget required.

50.8 WG guidelines for spending additional budget • A draft proposal of the guidelines was prepared by P. Bàrberi and circulated within SciCom and the Board beforehand. The guidelines were approved and will be forwarded to the Board for final approval and official endorsement by the EWRS. 50.9 EWRS Book on cutting-edge weed research (to be published by Wiley-Blackwell) • P. Hatcher proposed to write a book on cutting-edge weed research, backed by Wiley-Blackwell. The idea that each EWRS Working Group writes a chapter pointing out the most innovative research recently carried out on their subject and the key points that are likely to become relevant in the foreseeable future. A draft roadmap was presented, with the objective of printing the book in the second half of 2011. SciCom backed this idea with enthusiasm. WG Coordinators were invited to structure a draft plan of the chapter by indicating the subjects to be treated and the collaborators to be involved. This plan will be sent to P. Hatcher and R.J. Froud-Williams (book editors). Although the book will not possibly show the EWRS logo on the cover, the two editors will take care to duly acknowledge the contribution of the EWRS and its WGs in the book foreword. 50.10 Any other issues • None. 50.11 Next meeting • 51st SciCom meeting: Kaposvár (HU), Saturday 10 July 2010 (whole day).

A one-day workshop in Delémont, Switzerland 7 December 2009

by Christian Bohren and Paul Hatcher; [email protected]; [email protected]

Common ragweed, Ambrosia artemisiifolia, is an exotic weed in Europe affecting human health, agriculture and biodiversity. Initiatives in several countries have developed early detection and management methods. Projects for sustainable integrated control strategies to reduce its abundance in already well-infested areas are still missing. CABI Europe – Switzerland and EWRS working groups on "Invasive Plants" and "Biological Control" organised a workshop to discuss sustainable management of common ragweed in Europe. Interested researchers were invited to a meeting in Delémont, Switzerland in December 2009. The meeting offered an excellent opportunity to get up to date information on Ambrosia research taking place in Europe and worldwide. Particular emphasis was placed on biological control, especially on:

• The potential for classical biological control of Ambrosia in Europe • Integration of biological control into current management methods • Risk assessment required for introducing biological control organisms • European and National legislations and regulations of invasive alien plants and of classical

biological control in Europe The first day of the workshop attracted 55 registered participants from 16 countries both in Europe and also including China and Canada. Gerhard Karrer (University of Vienna, Austria) gave the first talk, on the invasion history and dispersal processes of ragweed in Europe; this theme was continued by Jacqui Shykoff (CNRS, France) who also considered the effect of natural enemies of the weed. Edita and Ivan Štefanić (University of Osijek, Croatia) then described the impact of the weed in Croatia and how it might be managed. Bernard Clot (Météo Suisse, Switzerland) then discussed the serious impact of ragweed pollen upon human health and Eladio Fernández-Galiano (Council of Europe, France) described the problem of invasive alien species in Europe and Europe-wide strategies to control them. Papers after lunch considered how ragweed could be managed. Christian Bohren (Agroscope Changins, Switzerland) started by discussing mechanical and chemical control strategies and André Gassmann (CABI, Switzerland) then described the biological control programmes that had been carried out against ragweed in Russia, China and Australia. These had mainly considered insect biocontrol agents, but Levente Kiss (Hungarian Academy of Sciences, Hungary) then described work carried out on using fungal pathogens for ragweed control, and Jian-Ying Guo (Chinese Academy of Sciences, China) and Sergey Reznik (Russian Academy of Sciences, Russia) described the biological control of ragweed in China and Russia respectively. Finally, Urs Schaffner (CABI, Switzerland) finished the session by considering the regulation of biocontrol agents in Europe. Seventeen posters were also displayed. These covered the status of the weed in Poland, Croatia, Italy and Germany, allelopathic interactions between ragweed and other plants, the effects of soil disturbance on ragweed abundance, ragweed drought tolerance, pollen dispersal and control methods. The second day of the workshop was organised for a small group of experts to discuss the planning of projects on integrated control strategies. The morning was dedicated for the presentation of various funding opportunities as EUPHRESCO, COST, ERC Funding and "Marie Curie Fellowship". The importance of integrated management activities was again emphasised. The participants agreed to split forces for submission of project proposals with integrated approach to various institutions. Pdfs of all the talks and many of the posters can be found at http://www.cabi.org/ambrosia. We will continue to inform our readers on the development of new projects on integrated ambrosia control in due time.

Julius Kuehn Institute (JKI), Dept. of Weed Science, at Braunschweig, Germany Hans-Peter Söchting & Thomas Eggers; [email protected]

Since man started to grow crop plants wildly growing plant species with similar characteristics and requirements appeared as well on the fields. These unwanted wild plants are called arable weeds. The weed flora in Germany consists of some 250 species; representing almost 10% of the whole German flora. In the weed exhibition garden of the Julius Kuehn Institute (JKI; former BBA, Federal Biological Research Centre) characteristic weeds have been collected and grown since 1972. The vast majority of the weeds are annual species (therophytes). Perennial species are grown in a separate part of the exhibition area.

The weed species, which are grown in pure stands, are not only exhibited for the public but are also cultivated and reproduced in order to gain seeds for further investigations on their biology and ecology (germination, development, flowering, and fruiting). From this collection a limited quantity of seed material is handed out for scientific purposes and maintenance in other exhibitions as well as for education and public relations. Consolida regalis Caucalis platycarpos

About 125 plant species, that are typically found in fields, gardens and vineyards (segetal plant species) are grown every year. Taking in consideration that some 100 arable weed species are listed in the Red Data Books of endangered vascular plant species in Germany, this garden has a unique role in collecting, conserving and presenting species like Caucalis platycarpos, Asperula arvensis, Consolida regalis, Conringia orientalis, Sherardia arvensis, Neslia paniculata, Agrostemma githago, Arnoseris minima, Cuscuta epilinum, Adonis aestivalis, Legousia spp., Kickxia spp. and so on.

Consolida regalis Agrostemma githago Legousia spp.

The herbarium of the JKI is regularly supplied with plant material from the weed garden, especially with different growth stages of the weed species.

The weed species are generally grown in separate plots. Their common and scientific name, life-form, ecological behaviour pattern, origin and distribution as well as the kind of propagation are displayed on signs posted at each plot.

HHIISSTTOOLLOOGGYY OOFF AALLOOPPEECCUURRUUSS MMYYOOSSUURROOIIDDEESS HHUUDDSS..

Dear Colleagues, This time, I will present slides of a nasty European weed: Alopecurus myosuroides Huds. or blackgrass (Bayer Code : ALOMY). Why do I call it nasty? First, farmers have tried to control it for half a century and you can still find the same number of individuals in crops or even more than before. You may count up to several thousand plants per m² in a UK or German cereal field. Blackgrass is rather limited to Central and Northern Europe. Blackgrass is nasty for a second reason: unfortunately, it is one of the species that has developed resistance to all kinds of herbicides: PS II-inhibitors, ACCase-inhibitors, ALS-inhibitors… you name them. Our EWRS Resistance Working Group spends a lot of time on this weed. Botanists have described quite a number of Alopecurus species in the world; but only a few became real weeds. In Asia e.g., Alopecurus myosuroides has an interesting counter part: Alopecurus japonicus Steudel (Bayer Code : ALOJA). This species has developed resistance to herbicides in China just as Alopecurus myosuroides did in Europe.

The seed of blackgrass germinates with a coleoptile and a radicle as shown in the next picture:

Staining of shoot sections with methylene blue result in views as shown below:

Vascular bundles are distributed over the whole section as typical for all grasses. You may find chloroplast containing parenchyma, a so called chlorenchyma, in the peripheral parts of transverse sections.


12

Roots are much more interesting. They have a large central vessel just like other grass weeds , e.g. Apera spica-venti, Lolium multiflorum or Poa annua.

The cortex of some grasses starts disintegrating after some time, especially when plants are well watered. This is why the cortex may be out of focus in the picture above (stained with toluidine blue). The next slide was stained with a modified Etzold technique (see Newsletter 108).

This dye mixture makes the characteristically arranged phloem visible (deep blue, reminding of a pentagon divided into three parts). My next contribution in Newsletter 110 will be devoted to Amaranthus species Hansjörg Krähmer [email protected]

Instructors: Jon Marshall, Editor-in-Chief Weed Research (Marshall Agroecology, UK) and Jens Carl

Streibig, Faculty of Life Sciences, University of Copenhagen. The Workshop will be held in conjunction with the 15th EWRS Symposium (European Weed Research Society), 12-15 July 2010 in Kaposvár, Hungary. Description Science is hard to read and understand and its difficulties are born out of necessity, out of the extreme complexity of scientific concepts, data and analysis. But complexity of thoughts need not lead to impenetrability of expression. We believe that improving the quality of writing actually improves the quality of thought and the quality of the science. Without communicating our work, science cannot advance or be applied where it can make a difference to human endeavour. The workshop will approach the questions: Why publish? When to publish? And where to publish? The structure of a paper submitted to Weed Research. What is the editor looking for in:

• Title page • Summary • Keywords • Introduction • Materials & Methods • Results • Discussion • Acknowledgements • References • Tables • Figures • Appendices • Supplementary information

Should I do the research and then write, or the other way around? Each participant should bring a draft manuscript and be prepared to share the draft with others on the course. Participation to this workshop of the EWRS ‘Education and Training’ Working Group is free for members of the EWRS and for registrants to the 15th EWRS Symposium. Others must pay a workshop registration fee of 60 EURO, which corresponds to the annual membership fee to the EWRS. Registration will be available online starting December 1st at www.ewrs.org. The number of participants is strictly limited to 20, on a first-come, first-served basis. Please apply early.
