2 Abstract submission: One page abstract should be submitted by June 15 th. Guidelines for the preparation of abstract Abstracts should clearly state: Title: Short and concise. Background and objectives: state the rationale or hypothesis followed by objectives. Methods: briefly discuss the experimental design and key methodologies. Results: present the main results with appropriate data analysis and pertinent discussion. Conclusions: limit the conclusions to those that are directly supported by the results. Use Latin names for organisms when first mentioned. Use common names of chemicals (no trade names are allowed) A4 page; all text in Times New Roman, 2.5 cm margins Title: Centered, font 14 pt.

Box 1021, Ramat Yishay, 30095, Israel. eizenber@volcani.agri.gov.il. 2 Wyler Department of Dryland Agriculture, Jacob Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev, Sede-Boqer Campus, 84990, Israel The aim of this study was to develop an in-situ, non-destructive method for observation and monitoring of the underground developmental stages of the root parasite Orobanche cumana. The parasitic weed Orobanche causes severe damage to vegetables and field crops. Most of the damage occurs during the underground, unobservable parasitism stage. Sunflower (Helianthus annuus cv. Adi) plants were planted in a soil that was artificially inoculated with O. cumana seeds. Clear Plexiglas minirhizotron observation tubes were inserted into the soil. Seed germination, early stage of penetration, and formation of tubercles and spikes were observed non-destructively and were monitored as video images throughout the growing season by means of a minirhizotron TV camera. Use of this technology enabled to monitor the complete individual parasite life cycle, from germination to Orobanche shoot. In addition, the effect of the systemic herbicide imazapic on the development of O. cumana was inspected and quantified. This novel methodology facilitates the in-situ study of major aspects of the host-parasite interaction, parasitism dynamics, parasite growth rate, and the effect of chemical treatments on the parasite. Key words: broomrape, chemical control, image analysis

Provisional programme Sunday 29 th September 2013 Arrival, sightseeing, etc. Afternoon and evening: Registration Welcome drink and dinner Monday 30 th September 2013 Morning: Registration Morning and afternoon: Scientific programme Evening: Dinner Tuesday 1 st October 2013 Morning: Scientific programme Afternoon: Scientific programme Evening: Dinner at a local place Wednesday 2 nd October 2013 All day Scientific and touristic excursion Thursday 3rd October 2013 Morning: Scientific programme Afternoon: Scientific programme and Summary Friday 4th September 2013 Departure Scientific programme As usual, the workshop aims to be informal and so stimulate as much discussion as possible among participants. As in past workshops, we will combine plenary scientific sessions with oral and poster presentations, round-table discussions, and a final plenary session (reports on round-table discussions, directions for the future, etc.). Session chairs will briefly introduce each poster associated with the theme of their oral session presentations. We would also like to organize some keynote themes presented by invited speakers. This will be followed by an extensive discussion lasting min. You are welcome to suggest relevant speakers and themes. Below is a tentative list of topics: Novel and sustainable weed management in arid and semi-arid agro-ecosystems Weed biology, ecology and modelling Herbicide behaviour in soil and the environment Invasive weeds in arid zone: control and quarantine regulations Weed management in organic farming systems Preventive and integrated weed control (crop rotation, tillage system, etc.) Weed management in irrigated and non-irrigated crops Weed management in minor crops and special situations Cover crops, mulches and intercropping Site specific and precision agriculture - new developments and technical innovations Weed population dynamics in physical and cultural weed management systems Parasitic weeds and herbicide resistance Environmental impact of weed management Weed Mapping Small scale weed mapping Regional mapping and country surveys Weed resistance mapping Mapping of invasive weeds Mapping of rare weeds The application of GIS systems in weed surveys The development of geodatabase for weed surveys and weed management Climatic change and weed flora shifts Weed distribution and land change
