From the President 0 ne of the most important events in

the Society's calendar takes place in Copenhagen in June. The Second International Weed Control Congress, co-hosted by the European Weed Science Society, will address the theme, Rationalizing Weed Control Options, in a five-day meeting attended by delegates from many parts of the world. The number and diversity of the papers to be presented is testament to the global importance of weeds, whether they are in advanced agricul- tural systems or the subsistence farms of developing countries. Despite decades of technical progress in farm- ing, there is no evidence that weeds are declining in importance. Farmers in developing countries, if anything, are being challenged even more by weeds as they struggle with shortages and high costs of labor for weeding and poor resources to adopt technology which could alleviate their plight. Now, as never before, the Society has to promote the science which it repre- sents.

The four-yearly congresses are undoubtedly one of the most important vehicles for propagating our aims. The Congress in Copenhagen will be no exception. In fact, it will be an oppor- tune time to review our role within the intemational weed science community. Are we doing the right things? Could they be done differently or better? These issues are being discussed within the Executive Committee but it is imperative that the wider membership has its say, if not at the Congress, then certainly by correspondence which could be published in the Newsletter.

An important decision to be taken at the Congress in Copenhagen will be the venue for the Third International Weed Control Congress which will be

held in 2000. With contenders from north and south America, Africa and the Middle East, there is no dearth of good organizations willing to co-host the next Congress. This will provide opportunities for the IWSS to further its international objectives while support- ing its national or regional partners. Our members should bear this in mind when they vote for who that partner will be.

Two further important decisions must be made. In February, 1997, the positions of Vice-President and Secre- tary-Treasurer of the Society must be filled to replace outgoing office bear- ers. The success, even the survival, of our Society depends on finding tal- ented individuals to lead us towards the next millennium. Nominations have been invited and balloting will soon take place to fill these important posts

I look forward to meeting many IWSS members in Copenhagen and to welcoming new members who will be joining us. I regret that many will be unable to attend the Second Congress but I hope that all our members, whether or not they are present, will feel that the Society has looked after and promoted their interests in weed science.

--John Teny, IWSS President

1996 Outstanding Achievement Award-Developing Countries

Dr. Ramiro de la Cruz Dr. Ramiro de la Cruz received the 1996 IWSS Outstanding Achieve- ment Award-Developing countries. Dr. de la Cruz is currently at the Escuela Regional del Tropico Humedo (EARTH) in Costa Rica. He was bom in Colombia in 1940 and graduated in 1963 as an agronomist from National Univer- sity of Columbia. Later, he ob- tained his MS (1969) and PhD (1 974) from Iowa State University. As a senior Weed Scientist, Dr. de la Cruz worked at the Tropical Agricultural Center for Research and Education (CATIE).

His contribution is significant in a region of the world where re- sources are so limited. As part of his duties with CATIE, Dr. de la Cruz frequently participated in teaching and provided technical assistance throughout Central America and South America. He taught Weed Science at CATIE's graduate program, leading educa- tional activities at the graduate level in Central America. As part

r,

of his responsibilities, Dr. de la Cnrz also participated in other

.b graduate courses, especially those related to Integrates Pest Manage- ment. Twelve graduates majoring in Weed Science under the direc- tion of Dr. Cruz are contributing in their respective countries.

Dr. de la Cruz also pioneered several weed research areas in Central America. His efforts to understand the biology and ecol- ogy of itchgrass (Rottboellia cochinchinensis) in the tropics, including seed bank dynamics,

growth patterns, weed-crop interactions and management options have made a significant contribution in weed management systems. His efforts led to broad- ening weed science research and extension beyond simple "weed control," as he promoted a long- term "ecological systems ap- proach" to vegetation manage- ment. His contribution in the use of cover crops to suppress weeds under our conditions in Central America is well recognized.

For the first time, he reported the incidence of herbicide resis- tance of weeds in Latin America, when he documented that popu- lations of Echinochloa colona from Costa Rica had evolved resistance to propanil. His work in Colombia was mainly associ- ated to the lnstituto Colombiano de Agricultura (ICA) where he developed various weed control techniques for crops such as cotton, sugarcane, soybeans, maize, beans and rice.

He also has served as a con- sultant for FAO, USAID, and IICA. Dr. de la Cruz is a founder of the newly established Costa Rican Weed Science Society and a member of the IWSS and WSSA. Ramiro's contributions to the advancement of weed science research and education in the developing world, specifically in Latin America are of significant importance to international weed science.

-Raj Prasad, IWSS Secretary-Treas.

Date: February 6. 1996 Location: Norfolk Waterside

Convention Centre, WSSA Annual Meet- ing, Virginia, USA

Time: 7-10 pm Attendees: Okezie Akobundu (Nigeria), Prasanta Bhowmik (USA), Bob Callaghan (USA), Ramiro de la Cruz (Costa Rica), Gerry Doll (USA), Chester Foy (USA), Clyde Elmore (USA), Jonathan Gressel (Israel), Whitey Holm (USA), Yeshaiahu Kleifield (Israel); Susan Larson (USA), Robert Norris (USA), Abelino Pitty (Honduras), Robinson Pitelli (Brazil), Raj Prasad (Canada), Jens Streibig (Denmark), John Terry (UK), Bemal Valverde (Costa Rica).

President John Terry called the meeting to order and thanked all for their participation. The agenda, as submitted, was adopted and the Secretary's report was read by Raj Prasad from the published minutes from Septem- ber 1995 newsletter. There being no questions, the Secretary's report was accepted. Susan Larson then tabled the financial report (published in the June 1996 newsletter). Total assets are $3,267.79, mostly ($2.282.82) coming from membership dues. A sum of $2.000 was received from the CIBA-Geigy Ltd for publication of two newsletters. Most of the money was spent on publication of two newsletters and a directory. All bills have been paid.

members hi^ U~date: Life mem- bers 136, Individual members 421 ; Total 557 members. Clearly greater efforts are needed to increase membership and all were urged to help. EWRS, Israel WSS and other regional weed science societies must be approached to enroll more members. It was suggested that all regional WSS should collect dues for IWSS and that for this purpose a special

representative should be desig- natedlappointed at each regional meeting. At the forthcoming I WCC, Copen hagen, active enroll- ment of new members should be undertaken and all future Con- gresses should include listed membersip. Sponsorship of new members in developing nations was discussed. Many members were sponsored for only one year but they could not renew their dues, owing to lack of foreign exchange or expenses. It was proposed that the minimal period of sponsorship should be three years.

S~onsorship to attend the 2nd IWCC - Copenhaaen: Several requests for bursaries have been made by weed scientists from developing countries to attend the Congress. Jens Streibig has no sponsorship money, nor can he offer any partial support, e-g. free registration or board and lodging. Dr Labrada (FAO) may have some funds for sponsorship and it was agreed by all that opportunities should be provided to bring few promising young weed scientists to such Congresses. Dr Labrada is preparing a selection criteria for some candidates. It was also emphasized that candidates be encouraged to seek funds from their local or regional WSS or agrochemical companies.

Newsletter U~date: Susan Larson (Editor) has produced two newslet- ters annually and the membership directory, in spite of problems she is facing at the Oregon office. Efforts will be made to resolve these problems. More news items, technical articles, calendar of events, regional information, election of new officers and timely articles (e-g. on the development of herbicide resistance in tropical weeds and on the control of para- sitic weeds) are needed. A new column on Letters-to-Editor should be introduced and weed scientists from the regions encouraged to

voice their opinions. The new membership directory has errors that need to be corrected but all members will be asked to supply phone, fax and e-mail addresses wherever applicable. The Secre- tary wrote over a dozen letters to chemical companies and others for support ($2,000) to publish the r" two newsletters. The response was not encouraging; only one (American Cynamid Co. USA) ei

donated $500 and the rest did not even respond. Further attempts will be made.

IWSS Elections: Elections are to be held to choose a new Vice- President and Secretary-Trea- surer. Calls for nominations will be published in the IWSS. and WSSA newsletters.

IWSS Awards: Chairman Bhowmik announced the result of elections for two awards. Dr Chester Foy (USA) won the outstanding award from the developed-nation category and Dr Romero de la Cruz (Costa Rica) for the developing-nations cat- egory. Both were congratulated and plaques will be presented to them at the Congress in Copenhagen. The newsletter will contain an application form and guidelines for the nomination of candidates to receive outstanding achievement awards in 1997.

IWCC Co~enhaaen: Dr Streibig reported that all arrangements are .. in order and that over 400 del- egates are expected to attend. Over 100 requests for financial -. support have been received from Third World Countries but only limited offers can be made. CIBA-Geigy Ltd. is sponsoring a Symposium and some funds ($500) may be available for participation. Many donors [Jim Riggleman; EU Commissioner on Weed Control & Environment; Danish Goverrnent (Ministry of Environment and others)] have

Meeting Minutes continued ... contributed significant funds for the Congress. Some concern about the goals and objectives of these Congresses was expressed by Dr Holm who felt that the theme of food production should be emphasised. He suggested that an appropriate theme for the next

fl IWCC in the year 2000 would be Weed Control for Food Production

4 Venue for the next IWC Conaress: Four countries, Brazil, India, South Africa, and Israel, have shown interest in hosting the next Con- gress in 2000. Dr Kliefield (Israel) provided a detailed invitation package from his country but this was not discussed at the meeting. It was decided that similar invita- tions be sought from other. A committee headed by the Vice- President will screen the applica- tions and put them forward at the AGM in Copenhagen where the members will vote on the venue of the next Congress. This commit- tee will also establish some guide- lines for selection of future sites. Procedures for bidding to host the next Congress will be published in the June newsletter.

Re~or t on Panels: During the Melbourne Congress, several panels were created to look into different aspects of the weed control activities. The President has to present a 30-minute report on these at the Copenhagen Congree. The status of these

+ panels is: 1. Definition and categoriza-

Strategy for Water Hyacinth Control Fort Lauderdale was the venue for a meeting on water hyacinth, Eichhomia crassipes, jointly organized by the FAO, University of Florida and the USDA-ARS in September 1995. Delegates representing organizations in Australia, Netherlands, UK, Benin, South Africa, Uganda, Ghana, Mexico, Argentina, and the USA contributed papers and expert advice during the four-day meet- ing.

In the first session, an overview was presented of water hyacinth problems in developing countries, followed by specific reviews for West Africa and Lake Victoria. Two sessions dealt with programs for the control of water hyacinth in Ghana, Australia, Benin, South Africa, Mexico, USA and Malawi. A session on control methodolo- gies concentrated primarily on practical experiences of biological, chemical and mechanical control in the USA.

With this background, the delegates debated a strategy for the integrated control of water hyacinth which could be sup- ported or implemented by FA0 and other sponsors. Biological control was strongly recom- mended because of its proven efficacy in some countries and potential for use in many others. Chemical and mechanical control were perceived as having a place in the integrated control of water hyacinth but of being generally less appropriate than biological control in developing countries.

The proceedings of the meeting will be published in 1996. They will provide a valuable state-of- the-art review of water hyacinth control and indicate appropriate reseasrch strategies, particularly for developing countries.

According to Zeneca, natural products. from the bacterium Pseudomonas fluorescens may provide a novel source of potent new herbicides. Monic acid, a herbicidally active derivative of pseudornonic acid, has been shown to be particularly effective against broad-leaved weeds in cereals. Zeneca claims that a low environmental impact and the potential of a new mode of action give the substance considerable potential.

Herbicides-Tolerant Crops According to AgrEvo, crops which have been genetically modified to make them tolerant to non-selective herbicides may require additional properties to make them economically attractive to farmers. AgrEvo is currently trying to link the marker gene which imparts herbicide resistance to other genes controlling beneficial characteristics. An example would be linking the herbicide resistance gene with rhizomania resistance in sugar beet. In Second Quarter 1995, Canada approved the first oilseed rape variety genetically-modified for resistance to the herbicide glufosinate- ammonium (Challenge). Full registration approval of Challenge for use with modified crops is expected in France in 1997 and in Germany and the UK in 1998.

Regional Project for Biological Control of Chromolaena Odorata in Africa

Chromolaena odorafa (L) King & Robinson was introduced into Africa between 1936-37 from Ceylon. Today the weed has colonized the whole of Western Africa, parts of Central and South Africa. Indications are that the remaining parts of Central Africa and East Africa are under serious threat of a similar invasion. The presence of this weed in continental Africa has created many problems in agricultural production, forestry, pastures and biodiverstty. Added problems include bush fires and increased pestilence of Zonocerus grasshoppers.

Despite claims of some useful attributes of Chromolaena in agriculture, consevation and medicine, the ecological dmage caused by this weed justifies its control. In view of the menace of Chromolaena, the FA0 funded a project in 1991 to determine the introduction, distribution and spread of the weed in West and Central Africa. This was followed by a TCP project to confirm the weed status of Chromolaena as reported in the

European Group Will Host Symposium The European Weed Research Society (EWRS) is one among the group of specialized international professional groups devoted to pest management. A key objective involves promoting weed research throughout Europe.

Periodically the Society sponsors an international symposium. The 10th such meeting has been scheduled for June 1997 in Poznan, Poland.

EWRS also assists with communication between weed researchers, and encourages the overall advancemet of weed science and technology, according to the Society's stated objectives.

survey results. A regional workshop, with the participation of specialists from seven countries was organized and conducted in Abidjan, Cote d'lvoire, February 5-7, 1996 to discuss the ways for integrated management of the weed with major component on biological control and to draft the main objectives of a long term projet on Chromolaena odorata control. The workshop requested the governments of participating countries pay sufficient

atltention the this weed problem and to strengthen national capacities of agricultural research with regard to integrated management of C. odorafa. The workshop also called international donor communrty to assist the countries with funds to implement a common IPM program for C. odorata control.

James Duke Honored as FAR-B Distinguished Scientist Dr. James A. Duke, a recently retired researcher at the Beltsville Agricultural Research Center (BARC) has been selected by The Friends of Agricultural Research- Beltsville Inc. (FAR-B) as their 1996 Distinguished Scientist.

Duke was honored for his work exploring and collecting plants in the U.S. and in other countries that have valuable genetic proper- ties, especially natural dyes, natural pesticides, and natural medicines. In addition to identify- ing important plant resources, he also worked with other countries to investigate the potential for them to develop alternative agricultural crops and industries.

FAR-B, which is a non-profit group dedicated to supporting research and education programs

at BARC, honors an outstanding scientist each year whose research is associated with the subject of the annual BARC Symposium. This year, the BARC Symposium, held May 19-22, is entitled "Global Genetic Resources - Access, Ownership, and Intellectual Prop- erty Rights."

Duke was hired as an ecologist by the Agricultural Research Service, USDA, in 1963. Although he left ARS in 1965 to join the Battelle Columbus Laboratories to conduct ecological and ethnobo- tanical studies in Panama and Colombia, he returned to the agency in 1971. Until his retire- ment last year, Duke undertook numerous assignments relating to crop diversification, medicinal

plants, and energy plant studies in the US. and in developing coun- tries.

Among his many projects, Duke has prepared an encyclopedia of economic plants and collaborated with the National Cancer Institute on their AIDS and cancer screen- ing programs.
