Bärbel Gerowitt, Vice-President EWRS Dear colleagues, Our society EWRS is in a good shape: In terms of science we have active working groups, we organize and participate in meetings, international symposia and conferences. We also run a successful journal “Weed Research” (thanks to Jon Marshall as Editor-in-Chief, the Editorial Board members, reviewers and authors!). In terms of finances, the income from this journal, member numbers, which are fairly stable compared to other scientific societies and a responsible budget management result in a solid financial status (thanks to Ben Post as treasurer!). In terms of equality EWRS mainly acts regardless of nationality, sex and age. Although, these basics are highly valuable, today I focus especially young scientists within EWRS. As agreed several time, I will not define “young scientist” in a terms of age, rather use the common EWRS-expression: scientists in their early steps of career – PhD-students and Post-Doc in their first projects. Several members, not only me, expressed that EWRS in general and the various bodies representing EWRS could profit from ideas, opinions and proposals of young scientists. Well, this cannot happen, if there are no activities, structures or information channels to mine this creative potential. Therefore I am very pleased to inform you about a spontaneous initiative within the working group Weeds and Biodiversity during the workshop in Pisa, November 2014. Many attendances were PhD-students or young scientists. While presenting current structures and bodies of EWRS in a talk I encouraged them to offer and demand attention within our society. During the workshop they decided to link themselves as network of young scientists in the working group Weeds and Biodiversity. Meanwhile this network has over 25 subscribers and they have started to exchange experiences and help each other in methodological questions. At the moment the initiative is informal and free of any allowances or expectations from the official EWRS bodies Board and SciCom. However, fields of engagement of EWRS-organized young scientists were quickly explored when we discussed that point in Pisa: EWRS-web pages and EWRS-presence in social networks. Moreover the young scientists there were highly interested in activities in Education and Training. For information about the initiative from the working group Weeds and Biodiversity contact: Agnès Salfat ([email protected]) or Christoph von Redwitz ([email protected]). As Vice-President I took over the patronage (or better “matronage”?) of this spontaneous initiative. I encourage young scientists in all other EWRS working groups to consider this way of linking-up and to come-up with proposals how this initiative can be passed into formal structures which support the development of EWRS in terms of scientific output and members. As already said, there is no EWRS mandate for special young scientist activities at the moment. However, if as Vice President I can help out with anything I am very willing to support and share. Our Symposium in Montpellier 2015 could be a good opportunity for discussion and preparing further steps (if agreed on). Meanwhile young scientist can inform themselves and start the discussion in their Working Group.

The EWRS working group Weeds and Biodiversity held a 2-day meeting at the Institute of Life Sciences of the Scuola Superiore Sant’Anna in Pisa, Italy, from 17 to 19 November 2014. The workshop was attended by some 23 participants of which half were young scientists. The president, vice-president and scientific secretary of the EWRS were under the attendance of the workshop. It had an interesting and diverse program, which included four scientific sections, several new topics for collaboration and a training session on communication. The workshop started with a general introduction on the origin of the WG (Bärbel Gerowitt) and future opportunities within the EU program Horizon2020 (Paolo Bàrberi). This was followed by four sessions with scientific contributions:

‘Agriculture and biodiversity’ (7 contributions) ‘Sampling and assessing biodiversity’ (3 contributions) ‘Ecological services’ (2 contributions) ‘Seed predation’ (4 contributions)

The small size of the group produced an amiable and informal atmosphere, which was conducive to discussions and dialogue. The proceedings of the workshop are being prepared and will be loaded onto the Weeds and Biodiversity WG pages of the EWRS website (http://www.ewrs.org/biodiversity/), as soon as the last contributions have been received. One afternoon was reserved for proposing and discussing collaborative work:

weed diversity (Bärbel Gerowitt) joint seed predation experiments (Paula Westerman) rare arable weeds (Henri Darmency)

None of these proposals resulted in anything substantial, but seeds have been planted and the proposed topics will be followed up in future meetings. A fourth proposal, namely to mobilize and organize our large contingency of young scientists in the WG (Bärbel Gerowitt), emerged spontaneously. This has materialized into a mailing list. For those of you who are interested in this initiative please contact Agnès Salfat ([email protected]) or Christoph von Redwitz ([email protected]). For the first time in the history of the EWRS, a new WG coordinator was elected, using a secret ballot. Previously, Bärbel Gerowitt had decided to step down as convenor of the WG, because she deemed her duties as chairperson of the EWRS SCICOM incompatible with those for the working group. There was one candidate, Paula Westerman, who was elected almost anonymously (one abstained). The workshop was concluded with a training session on communication, led by the Chiara Tuoni, a communication expert. After an introduction on the role of communication and an overview of hands-on communication tools, the participants were put to work, creating posters for different target groups (farmers, funding agencies and scientists), addressing ecosystems services provided by weeds. The presentation on communication by Chiara Tuoni and the posters that resulted from the exercise will be made available on the Weeds and Biodiversity WG pages (http://www.ewrs.org/biodiversity/). The workshop was success thanks to the excellent preparation and organisation by the local organisers (Paolo Bàrberi, Federica Bigongiali, Gionata Bocci, Stefano Carlesi, Ambrogio Costanzo & Camilla Moonen) and the enthusiastic input and contributions of all participants. Many thanks to all! WG coordinator; Paula Westerman

by Ana Isabel Marí León; [email protected] When I read the email explaining that I had been chosen as a candidate for the travel grant that the EWRS gives for young scientists, I couldn’t be more grateful. My supervisor encouraged me to ask for it, “we will never know unless we try”, she told me. I decided to apply for it because this workshop would enrich my studies and career as a future scientist. As long as I could imagine it could be an opportunity to meet professionals from different countries, having the privilege to participate in interesting conversations about trials and anecdotes… Moreover, the theme of the workshop is closely related to my everyday job. Moreover, it was the first time I visited Italy and I took advantage of the situation and traveled the weekend before the workshop to Florence and Lucca. Amazing at each step I gave I didn’t have enough space in my mobile phone to catch all the details! As a lover of gastronomy I have to admit I tried very good dishes, a part from the amazing pizza! After a dazzling weekend I took a train to Pisa, where my supervisor was waiting for me, ready to have dinner on a restaurant that serves a typical dish made with chickpea flour prepared on a wood stove named ‘cecina’. After a morning walk through this charming city, we met at the Scuola Superiore Sant’Anna on November 17 to 19 to start the 5th Workshop of the EWRS. As a way of presentation Dr. Gerowitt explained the trajectory of the Weeds and Biodiversity working group until today; afterwards, Dr. Bàrberi linked with how the future is going to be for Weeds and Biodiversity and the demands of the Horizon 2020. The rest of the program consisted in three sessions. The first one, “Agriculture and Biodiversity” included topics like rare weed species in Poland, the impact of weeds on Hungarian rice, the changes in vegetation in Germany, the effect of a mulch on maize weeds, how a cover crop affects the weed composition, what are the factors that change community composition in Latvia and the response of the conservation agriculture practices. During the “Sampling and Assessing biodiversity” session we could listen and discuss about the importance of rare segetal species, the effects of weeds on crop yield and their ecological services, the comparison of two statistical methods to determine the validity of the data, the role of weeds on pests and natural enemies and finally the benefits of introducing a legume crop in rotation on weed management.

Then, we learned about the importance of the “Seed predation” throughout the last session referring to reproduction of Centaurea cyanus, how the duration of seed burial affects predation by carabids, the influence of the distribution of the ant nests on weed predation, and to finish, the Echinochloa crus-galli population dynamics after predation on maize. Apart from these, three interactive sessions were carried out by different researchers trying to find a collaborative research; it was a great opportunity for colleagues interested in these topics. As a way of finishing, the useful intervention about ‘Targeting communication tools’ triggered lots of doubts about content, pictures and graphics that appear on our everyday job and were solved. A great idea by the organizers to include it. This led us to an interactive session, the topic was “ecosystem services by weeds”. We named them, pointed out what the scientific evidences of the services were at that moment, scored how relevant we though they are and for whom (farmers, scientist, policy makers). After sharing our ideas all participants split into three groups as they had to explain the ideas to farmers, researchers and policy makers by preparing a poster. It was a great exercise. The time was running out, the new coordinator was chosen (Paula Westerman) and the moment of farewell arrived. To sum up, the EWRS grant has given me the opportunity to share this experience with lots of professionals, discover a beautiful country and make my first international oral presentation, among other things. And, probably, the most important thing, a seed was planted. With the great amount of young scientists we were, we have created a EWRS Young Scientists Group to share information, doubts, help each other and catch up with news and, what is more important, to be in touch with these ‘weed’ colleagues from all different countries. Thank you very much!

By Jens Carl Streibig; WG Coordinator. Local coordinator: Prof. Dr. Işık Tepe, Department of Plant Protection, Yüzüncü Yıl University, Van. Teacher: Prof. Dr. Hayrettin Okut, Department of Animal Science, Biometry and Genetics, Yüzüncü Yıl University, Van. Teacher: JC Streibig, University of Copenhagen. Liaison: Prof. Dr. Hüsrev Mennan, Ondokuz Mayis University, Samsun. The course took place from 13 to 16 October 2014 at the Yuzuncu Yıl University, Van, Turkey. A total of 12 students participated, seven form Turkey, three from Iran, one from South Africa and one from Denmark. Unfortunately, the escalated warfare at the Syrian Turkey border made some Iranians cancel their participation. The teaching was focused on hands-on methods where the teachers gave a short introduction to analysis of variance, covariance, linear and nonlinear regression. The data were all related to crop and weed science. A significant part of the course was devoted to nonlinear regression and dose-response curves and the use of the add-on package drc for the R programme. On the basis of data brought by the students we went through the process of illustration the dose-response relationship and the curve fitting with the log-logistic model and the Michaelis Menten, as well as after fitting by estimation various EDx values and selectivity factors. It was very rewarding for all of us to work with real data generated by students and it had the positive spin off subsequent contact and discussion of problems after the workshop. The workshop also dealt with presentation of statistics in articles and why students should not blindly copy what other weed scientists have done in statistics.

TTHHEE HHIISSTTOOLLOOGGYY OOFF SSEENNEECCIIOO..

Dear colleagues, In this Newsletter issue, I would like to draw your attention to four representatives of the genus Senecio: Senecio inaequidens DC. (Bayer code: SENIQ), Senecio jacobaea L. (Bayer code: SENJA), Senecio viscosus L. (Bayer code: SENJVI) and Senecio vulgaris L. (Bayer code: SENVU). Their English common names are misleading as the same common names are sometimes used for different species. South African ragwort or narrow leaved ragwort is used for SENIQ, tansy ragweed for SENJA, sticky ragwort or sticky groundsel for SENVI and common ragweed, tansy ragweed or St. James-wort for SENVU. Senecio species have adapted to a great number of habitats. Many of them can be found on disturbed ground. Their number and diversity is considerable, especially in the mountain areas. Take a field guide and you will find out how many species of the ragworts and groundsel genus have succeeded in establishing on ruderal sites, especially on those where stress in any form plays a role. Most of them are typical nitrophilous species. Many Senecio species produce toxic pyrrolizidine alkaloids which can cause severe damage to the liver of animals and man. The symptoms are known as Schweinsberger disease. Horses may suffer severely when hay is contaminated with Senecio plants. S. inaequidens is a perennial, S. jacobaea biennial, S. viscosus and S.vulgaris are annual species. The inflorescences of all Senecio species consist of yellow or orange flower heads, the fruits are achenes. S. inaequidens is endemic to South Africa. It invaded Europe and the USA in the 19th and 20th century. S. jacobaea and S. viscosus are of Eurasian origin. S. vulgaris can be found worldwide.

Figure 6: Simultaneously germinating seeds of S. vulgaris in October Vascular bundles in stems of the here reported annual and biennial species are separate and arranged in circles as shown in Figures 7 and 8. The perennial species S. inaequidens produces phloem and xylem with a closed meristem ring in the secondary growth stage (Figure 9). Typical of Senecio species are resin ducts close to bundle caps (Figures 8 and 9).

Leaves of Senecio species are often covered with hairs. In S. viscosus, we find capitate glandular trichomes producing substances which make the surface sticky (Figures 10 to 12).

5-6 March 2015 Heraklion, Crete, Greece

The Working Group on Optimization of Herbicide Dose is pleased to announce that we will be organizing a workshop in Heraklion on the island of Crete (Greece) on 5-6 March 2015 with an optional field trip on Saturday 7 March. The theme of the workshop is: Optimizing herbicide use in an Integrated Weed Management (IWM) context. The workshop will be organized in conjunction with the Greek Weed Science Society (GWSS) after the closing day of the 18th Greek Weed Science Congress (to be held on 3-4 March 2015). The venue of the workshop is the Conference Centre “Kastellaki” owned by the Heraklion Chambers of Commerce and Industry (http://www.ebeh.gr/web/guest/home). The conference centre is located in cite centre. Why a workshop on optimizing herbicide use in an IWM context? Weed management in Europe is expected to undergo major changes in the future. In recent years the number of available herbicides has been steadily decreasing and the trend is expected to continue in the coming years following the launch of Regulation 1107/2009 due to its new and stricter criteria for registration of pesticides. It is also expected that the implementation of the Water Framework Directive will focus on herbicides as a key target priority chemical compounds. Concomitantly herbicide resistance is becoming more and more widespread and in particular non-target site resistance in several grass weed species is causing growing concern due the wide range of modes of action that these weed biotypes are exhibiting resistance to. Overcoming these challenges will require fundamental changes to weed management practices reducing the reliance on herbicides and increasing the adopting of non-chemical methods and cultural control practices. In this perspective, Directive 2009/128/EC with its demand for farmers to adopt IPM (for weeds IWM) to minimize the adverse effects of pesticides on human health and the environment, is very timely.


17

Despite a reduced availability of herbicides and increased problems with herbicide resistant weed biotypes, use of herbicides will, at least in the major crops, continue to be the mainstay of IWM strategies in the foreseeable future. An important research question to address is therefore how to optimize herbicide use in the context of IWM. For minor crops, where less herbicides are available than for major crops, more extensive changes to weed management strategies may be required. Tentative programme This workshop will specifically address the role and use of herbicides in an IWM context in both major and minor crops. Focus will not only be on the agronomic performance of IWM but also on environmental aspects such as drift including effects on non-target organisms and protection of surface and groundwater from herbicides. The workshop will accept submissions on all aspects of optimizing herbicide use in an IWM context but particularly encourage submissions on the following sub-topics:

• IWM and herbicide development • Combining non-chemical and chemical control methods • IWM and herbicide resistance • IWM in minor crops • IWM and herbicide application

Each session (sub-topic) will be opened with an introductory lecture given by an invited speaker. Subsidies for young scientists To encourage young scientists to attend the meeting, subsidies for young scientists are made available through the EWRS and can be applied for by sending an e-mail to [email protected].

In many countries, the results of long-term field experiments and long-term monitoring at known sites have been essential in the development of our contemporary knowledge base informing sustainable land use and management. The questions that can be addressed through data collected in existing long-term experiments and sites have often changed through their history and many have had to endure periods under threat. Such experiments can be expensive to maintain and often in politics and research only current problems drive the rhetoric that informs funding decisions. Perhaps, the needs of future generations are not, or not sufficiently, considered. Hence few new long-term experiments are currently being considered. Long-term field experiments will continue to be indispensable in future, as they cannot be replaced by new analytical techniques or models; on the contrary, they are an indispensable basis for the calibration and validation of these techniques. We look forward to a good set of discussions about the value of long-term sites and experiments for agriculture and ecology and would welcome contributions for all involved in the running of long-term experiments across Europe and the users of such long-term datasets in the development of policy and practice. Presentations and posters from this Conference will be produced together in a volume of the

Aspects of Applied Biology series. Copies will be available to delegates at the Conference. Abstracts of papers can be submitted by mailing or faxing the attached sheet to the AAB Office, or online via our web site at http://www.aab.org.uk.

Weed management in changing environments The European Weed Research Society (EWRS) and the French Association for Plant Protection (AFPP), together with the National Institute for Agronomy Research (INRA) and Montpellier SupAgro, are pleased to invite you to the 17th European Weed Research Society Symposium which will be held at Montpellier SupAgro, France. All holding institutions will make every effort to provide an excellent environment for a stimulating and enjoyable scientific symposium. The program will provide valuable information and networking opportunities for participants to discuss on any research, education and applied aspects related to weeds and weed management. Scientific program The EWRS Symposium aims at bringing people together to report on and examine all topics otherwise separately moderated by EWRS Working Groups (see http://www.ewrs.org). It will give emphasis on “Weed management in changing environments”. Weeds have a significant impact on the quantity and quality of agricultural products and on the ecosystems. The environments in which weeds thrive are constantly changing and weed management is challenged by regulatory, economic and environmental pressures. Weed populations are dynamic, rapidly adapting to these changing environments and weed management approaches. Weed research must adapt to new challenges, adopting state of the art technologies to deliver sustainable weed management solutions that limit weed adaptation and provide ecosystem services in agricultural systems. Furthermore the symposium will address current issues and novel approaches in weed biology, weed ecology, spatial aspects of weeds, crop/weed interactions, weed management approaches, chemical weed management and related disciplines. The program includes four days of sessions, with keynote papers, ordinary oral and poster presentations, platforms for discussion forums, and field trip. Side events, e.g. EWRS Working Group meetings and training sessions, will also be scheduled (tentatively on June 22; see other announcements in this Newsletter). Venue

The symposium will take place at the campus of Montpellier SupAgro (International Centre for Higher Education in Agricultural Sciences) which is well situated in a beautiful park in the city center of Montpellier. The urban agglomeration is nearly 0.4 million inhabitants. Montpellier is bordering the Mediterranean Sea in the

Languedoc-Roussillon province in South France. It is 3h from Spain and Italy and 1h30 from Marseille by car, 3h15 from Paris by TGV train, and direct links to Montpellier airport are operated from Paris, Brussels, Frankfurt, Copenhagen, London, Birmingham, Munich and Roma. The city and the region are of high touristic and culinary interest. The participants will arrange accommodation on their own as many hotels and resort places are proposed in the city, but we will do our best to propose a selection of hotels and book rooms at the student residence on the campus.

E-mail: [email protected] Objectives It is not the type of camera, its brand name or how expensive it is that makes the image, it is how the equipment is used. This workshop is all about how to use your camera to take better photographs. Everybody can take snapshots. This workshop intends to instruct you in how to use your camera controls to achieve its full potential while making photographs. More specifically, we intend to help you improve your composition skills in order to make photographs that are effective in documenting and illustrating the phenomenon that you observed or in conveying the information that you intended while optimising visual impact, precision, accuracy, and relevance. Course prerequisites Possess a camera and bringing it along with its manual of operations. Prior to the workshop, you will be given the opportunity to submit 5-10 photos that you have taken that will be reviewed in the course of this workshop.

Description It is often said that a picture is worth a thousand words. Photographs are often used in life sciences to document and / or illustrate a process, a technique, an experiment or a phenomenon. In weed science, for example, this means illustrating field techniques, field experiments or describing weed population spread or invasion of a given habitat, or taking photographs of a plant to help others in identifying it when they encounter that plant, etc. This workshop will cover the various aspects of photography, from the type of camera, to their functions and on how best to obtain the optimum picture considering the ambient conditions under which the photograph is to be taken. More specifically, we will cover:

The basic hardware Basic controls - camera settings Basic camera operations Composition Participant’s photos critique Equipment Camera care Advanced topics

o HDR o Workflow management o Image analysis

Fees and costs There are no fees to participate in this Workshop for members of the EWRS. Non-members will have to pay 60 € or, if a student, 30 €. These fees correspond to one year membership in the EWRS. If you wish to become member of EWRS, you can join the EWRS now at: http://ewrs.bureaupost.eu/en/main/Membership_application/Registration_form.

Objectives Science can be hard to read and understand and its difficulties are often born 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, as well as clearly communicating your work to others. The workshop will follow the course plan below and will try answering some of the key questions in written communication. At the end of the course, you should understand the process of writing, submission and review and feel comfortable in setting out to publish in an international journal. Course plan

Welcome Why publish? When to publish? Where to publish? The peer review process – what is it and how does it work? Scope and content: what and how much to publish? Journal style The structure of a paper: Title page, Summary, Keywords, Introduction, Materials & Methods,

Results, Discussion, Acknowledgements, References, Tables, Figures, Appendices, Supplementary information

Writing English – good and bad practice The science of statistics and data presentation Submission and ethical considerations After submission: decisions, responding to reviewers The final publication stages – copy-editing, proofs and reprints Questions Students present their own work Interactive student discussion Review and concluding comments
