NEWSLETTER OF THE INTERNATIONAL WEED SCIENCE SOCIETY

... President's Column

A Progress Report Friesen. President. IWSS Geor~e H.

This newsletter includes the minutes of an executive meeting held in Montreal, February 5, 1990. Including several invited guests, 18 weed scientists were present. These minutes indicate that considerable progress was made during the past 12 months. I am particularly pleased that IWSS has initiated an outstanding achievement award, and has named the first recipient, Dr. Lewis I. Okafor from Nigeria. Congratulations again. I believe that such recognition of our outstanding members indicates a certain degree of maturity of a society, and IWSS has reached that level of maturity. At this time I would also like to thank Dr. Jacob Ekodi for nominating Dr. Okafor.

There is a great deal of interest in the international weed control congress to be held in Melbourne, Australia, Feb. 17-21, 1992. Some questions about the program format have been raised by several of our members (see letters to the editor section), but most of these will be addressed in the second congress brochure.

Membership is IWSS is growing slowly, with about three or four new members added weekly, according to our executive secretary. This, too, is a good sign and indicates that our society meets an important need. I wish to thank all of our members who participated in the meeting in Montreal and all the members who submitted written reports and suggestions in advance of the meeting. Your comments and sound advice were most helpful. A

particular note of thanks to Susan Larson (Executive Secretary, IWSS, IPPC, Corvallis, Oregon) for keeping our finances in order, for typing, editing, and mailing our newsletters, and for compiling and printing an updated membership list.

Nominations for Vice-President

The International Weed Science Society invites nominations for the position of Vice-President. Submit your nomination with two supporting signatures to Dr. G.H. Friesen, Agriculture Canada, Box 3001, Morden, MB, Canada, ROG 1 J O .

The December 1990 Newsletter will include a mail-in ballot. The successful candidate will assume the office of Vice- Present on January 1 , 1991 and it is anticipated that he or she will assume the office of President on January 1,1993.

The above procedure and protocol is in step with the IWSS Constitution.

Minutes of 1990 Executive Meeting

Date: February 5,1990; 8:00 p.m. Location: Queen Elizabeth Hotel, Montreal, PQ, Canada

Attendees

Bill Ahrens, Prasanta Bhowmick, Jerry Doll, Clyde Elmore, Chester Foy, Robert Frans, George Friesen, John Gallagher, Leroy Holm, Harold Kempen, Susan Larson, Phillip Motooka, Sharad Phatak, Raj Prasad, Myron Shenk, Megh Singh

The President welcomed all and introduced Susan Larson who came from the Secretariat office in Corvallis, Oregon. Chester Foy moved and Bill Ahrens seconded that the agenda be accepted.

The Secretary, Raj Prasad, read the minutes of the last meetings. There being no questions, Gallagher proposed the minutes be accepted and Elmore seconded.

The untimely demise of the International Plant Protection CenterIOSU, Corvallis was discussed. In spite of concerted efforts made by scientists to defend it, USAID will only h n d the center until 1991. Shenk will be transferred to the newly created Integrated Plant Protection CenterIOSU, Corvallis, while Larson will remain in her present job.

Financial Rewort Susan Larson read the financial

statement which is published in this newsletter.

President's Rewort President Friesen announced that he

will be reading the annual report of IWSS before the business session of WSSA. Including responses to the questionnaire that was circulated, the President wrote more than 300 letters on behalf of IWSS.

Some of these letters included congratulations for awards received at Regional Weed Science Society meetings, for retirement and for long service rendered to weed science by scientists. All the supporting Regional Weed Science Societies were contacted. More contact needs to be established with weed scientists in Eastern Europe and USSR. The President is making efforts to visit and inform these countries of our IWSS activities.

The International Weed Control Congress 1992 is progressing well. The President visited Australia in July and discussed the current progress with the chairman, Harry Combellack.

Newsletter The President emphasized that

newsletters are greatly appreciated by the readers and form an important link between weed scientists and the Regional Societies of the world. Due to restricted readership and higher costs, translation of the newsletter to French and Spanish was not possible. Only an English edition is being published and circulated. After much discussion, Megh Singh proposed and Clyde Elmore seconded that this policy might serve the best interests for the present although if the Executive Board felt the need for translation into other languages, flexibility should be maintained. It was proposed that three newsletters per year should be published. Some members did not get these newsletters and so their addresses were updated. Each issue of the newsletter costs US$300 and, to economize, it was suggested by Gallagher and seconded by Elmore that the rWSS directory and letter be mailed together by commercial rate.

Membershir, Leroy Holm suggested that, like

WSSA, the IWSS should prepare and publish a directory of membership. Computers can be used for this purpose. Susan Larson has


the membership list produced by computer. Overall there are 880 members; 511 inactive; 244 active; and 125 lifetime members.

Constitutional Rewort Larry Foy read the report and noted

that since the 3rd draft of the constitution was prepared in 1977, no amendments have been made. The position of the Vice President is redundant and liquidated and this change needs to be ratified by the general membership a t the International Weed Control Congress in Melbourne in 1992. He suggested that the revised constitution be published in the December 1990 newsletter.

Awards Committee Report The report was read by the President

and after much discussion, the first International Award for Weed Science was approved in favor of Dr. Lewis Okafor of Nigeria. The award will be announced in the newsletter.

International Weed Control Conmess. 1993 All agreed that hosting of this

International Congress by IWSS is a good venture, that a relevant and useful theme should be developed, and that appropriate experts in various areas of weed science should be invited to speak. It was also agreed to invite the IWSS award winner, Dr. Okafor, to address the Congress. A poster session should also be included.

Journals to Develowine Countries The International Affairs committee of

the WSSA has developed a policy of shipping old issues of Weed Science and Weed Technology to developing countries and IWSS is cooperating. If weed scientists need financial assistance for publication of their paper(s) in Weed Science or Weed Technology, they should contact the editors and request exemption from excessive page charges. Clyde Elmore elaborated on this

issue and suggested that limited assistance can be made available through the WSSA.

Reswonse To Questionnaire The questionnaire developed by the

IWSS was very useful and provided much needed information on various aspects of membership.

Resolutions Committee Report Last year the Resolutions Committee

prepared letters, which were sent to Washington, protesting the closure of IPPCIOSU, Corvallis. These resolutions delayed the closure and have had some impact. This year it was resolved to write a complimentary letter to the Director of Agriculture Canada, Morden, Manitoba for allowing our President to use the secretarial services for all correspondence. It was also resolved that the Presidents of all Regional Weed Science Societies be awarded a token of US$200 for attendance of the annual general meetings of the IWSS.

Re~or t for WSSA Int'l M a i s Committee Unfortunately the Chairman, Robert

Williams, was unable to attend our meetings but Jerry Doll was present and substituted for Williams. Emphasis on improving communication between members of the International Weed Science communities was suggested.

Nomination of Executive President Friesen completed one year

and was requested to stay on until next year when the President-Elect, Chester Foy, takes over. This nomination was proposed by Myron Shenk and seconded by Prasad. The Vice President, Leon Smith, resigned due to his retirement from the Australian Civil Service. If needed, this post will be advertised in the newsletter.

Other Business The FA0 expert in weed science

June 1990 W S S Newsletter

resigned some time ago and this position is not being replaced. WSS paid the expenses of Susan Larson to attend the meeting in Montreal.

Meeting adjourned at 11:OO p.m. and the President thanked all for their participation.

Respecthlly submitted, Raj Prasad, Secretary

Melbourne Congress - An Update H a w Combellack

Chairman. Organizin~ Committee

Plans are on schedule for most things. To date we have over 60 replies from 15 countries. I plan to travel to the USA, Canada, England and continental Europe in September or October 1990 to promote the congress to industry and any other sponsors I can think of, e.g. World Bank, FAO, etc. I will leave the Asian circuit t o the deputy chairman, David Campbell. We believe the personal touch will be necessary and I will be leaning on my co-convenors to help organize the visit.

Details of the congress that have been worked out to date include: 1) the venue will be Monash University, including the Robert Blackwood Hall (seating capacity 1300), and the rotunda complex of 7 theatres (ranging in capacity from 150 to 300); 2) registration costs will likely be A$350 including lunch, dinner and proceedings; 3) accommodation costs from A$35 a t the University to A$200 or more at the Hyatt; 4) a range of pre-and post-conference tours for which we hope to engage a professional operator to ensure that the tours are educational and tax deductible.

There are still details to be finalized regarding the program, session convenors and key-note speakers, but this should be finalized soon. In addition to the above, we must also get industry representatives to attend and support the meetings. We trust the Congress will be of real value, particularly regarding future directions.

Journal Donations & Distribution

The International Affairs Committee of WSSA and the International Weed Science Society are cooperating in a program to distribute Weed Science and Weed Technology journals, books and other teaching aids to needy libraries and individuals. The objective is t o provide back

volumes of journals, etc. to those who would benefit from such gifts, particularly in developing countries. It is envisioned that the donors might be WSSA andlor IWSS members who have, or will be, retiring from active service and are no longer in need of their private collections.

Such collection and distribution is already being done by AAAS, Washington, DC, but their program is restricted to Sub- Sahara Africa. The joint venture described above is intended to facilitate distribution to needy libraries or individuals in other regions of the world. WSSA is providing an annual grant of US$1000 to cover shipping costs.

The first requirement is to obtain a --- -- list of libraries and 'individuals who would benefit from receiving such journals, books, etc. ~ l l members of ~ S S A or IWSS should inform this committee if they know of any such libraries or individuals.

The second need is to obtain a list of potential donors. Donors should prepare a list of journals, books and other teaching aids that they would like to dispose of, by providing names and volumes of journals, titles and authors and year of publication of books and other material.

All information should be forwarded to the following individual who will correlate all such information: Dr. P. Westra, Plant Pathology and Weed Science, Colorado State University, Fort Collins, CO 80523 / USA.

The Brighton Crop Protection Conference - Weeds 1989

Chester L. Fov

This conference was again held at the Brighton Metropole Hotel and the Brighton Centre, from November 20-23,1989.

The program followed the established pattern: invited papers on selected topics presented by authorities fiom Europe, USA and Canada, while research reports and poster sessions provided an opportunity for detailed presentation and discussion of basic and applied research. Although the program had no single narrowly defined theme, there was a major emphasis on environmental implications of vegetation management and on the range of ways in which adverse effects on the environment and wildlife can be minimized. In addition, several sessions were devoted to biochemical aspects of herbicide mode of action, crop and weed resistance to herbicides, herbicide movement in soils, persistence of herbicides in the soil, mode of action of graminicides, new production systems and their implications for weed control in horticultural crops, and novel aspects of weed control.

A highlight of the Brighton Conference is the traditional Bawden lecture, which honors a distinguished guest lecturer. The speaker in 1989 was Dr. I.J. Graham-Bryce, Environmental Affairs Division, Shell International Petroleum, The Hague, The Netherlands. His topic was

June 1990 IWSS ~ews le t t e r

"Environmental Impact: Putting Pesticides Asst. Secretary Mr. Y.A Asiru Into Perspective." Chemical & Applied

Products Ltd. Other sessions discussed current land PMB 1004, Apapa, Lagos use issues and their implications for Nigeria pesticide use, methods of reducing chemical

1 use, and the implications for weed control of ! recent developments such as farm woodlands

and the set-aside of arable agricultural land. As in previous conferences, much time was devoted to new herbicides and to the current use of existing molecules in a new geographic range of crops. Many of the sessions looked forward to the 21st century and its weed control requirements and opportunities, such as those posed by genetic engineering.

Society Spotlight

West M c a n Weed Science Society -

The society was inaugurated in April 1979 in Dakar, Senegal, under the leadership of Dr. 1.0. Akobundu of Nigeria; a senior Weed Scientist at the IITA, Ibadan, and the first president of WAWSS. The resolution for the formation of WAWSS was taken during the joint International Conference of IWSS, Weed Science Society of Nigeria (WSSN) and IITA held in Ibadan 1979. In West Africa, Nigeria has the strongest National Weed Science Society with a membership of about 50 persons from Research, Agrochemical Companies and

June 1990 IWSS Newsletter 1 Universities. The WSSN holds regular annual conferences and publishes two issues of Nigerian Journal of Weed Science each year.

Since inauguration in 1979, the WAWSS has successhlly held 3 conferences: Monrovia, Liberia, 3-5 August, 1981; Abidjan, Cote d'Ivoire, 17-22 October, 1983; and Ibadan, Nigeria, 4-8 November, 1985. The Monrovian Conference was jointly sponsored by IWSS, WAWSS, and WARDA (West African Rice Development Association). The 4th biennial conference could not be held in Lome, Togo in November 1989 for financial and technical reasons.

Membership of WAWSS stands at 40 regular members from 1 5 countries. This number usually swells to over a hundred during conferences. We generally get good support from industry.

Letters to the Editor

Dear Editor : We are weed scientists working on an

IPM project in Central America. We contact periodically with weed scientists working in research institutions and in universities and we have weed studies in several count r ies of Central America.

After reading your editorial in the December 1989 issue of the IWSS Newsletter, we feel that we could be the regional contac t fo r Central America (Costa Rica, Nicaragua, El Salvador, Honduras , Gua tema la ) , Panama, and Dominican Republic.

Please let us k n o w future dates planned fo r the IWSS Newsletter to send you informat ion regarding weed science activities in the region.

February 17-21,1992 First Internat ional Weed Control Congress


Dear Editor: Consideration should be given to

sending copies of Weed Abstracts to I developing countries. I feel that there are

advantages to sending this journal which, as you are aware, abstracts virtually all articles dealing with different aspects of weed

I

control, rather than sending weed science A journals (eg. Weed Science, Weed Research,

Weed Technology, Tropical Pest Management) which are rather limited in their scope.

I shall be returning to the Philippines at the end of the year following the completion of my sabbatical leave in Hawaii. Please note my change of address, effective immediately: International Rice Research Institute, P.O. Box 933, Manila, Philippines.

Keith Moody Past President, IWSS Honolulu, Hawaii

Dear Editor: The opportunity for IWSS to mature

hangs on the success of the 1992 congress in Australia; this is a gamble that must be taken. I concur with the majority at the Montreal meeting in that the program, as now set up, is too loose and general. Even with four or five days of talks, it would not be too difficult to accommodate more state of the art papers associated with the major crops, alternate control methods, new pest management concepts such as IPM or LISA that have developed over the past few years.

Some of us would like to see an aquatic weed management section that

A would let both the developing and the I developed countries see the direction of

research in this country--noting the effects of I, EPA restrictions and the environmentalist

movement. We are no longer a chemical only society.

The need to give those attending the congress something concrete to bring home will be most important as a justification for participation as well as reason to join the

society. For scientists in the USA and Canada, the importance of an invitation to participate cannot be overemphasized.

John E. Gallagher Raleigh, NC, USA

Dear Editor: Can we be helpful to the world? How

can we be unique and fill a void others do not care about? We need to be useful. Only a handful of people will attend such a meeting (IWSS Congress). For whom do we do this? Can we create something usefbl for the people who work down between the bunds and fences. Can we print something to help them also? I wish you all good luck in the months ahead.

Whitey Holm Madison, WI, USA

Dear Editor: I feel the same as others, that this

Australia meeting needs to be well attended by weed researchers throughout the world and as much information as possible be made available to people everywhere. All the people I know in the academic profession would have to be able to participate in the meeting and many would have to be invited by one of the program organizers in order to get approval to attend.

With these thoughts in mind, I would like to pass on to you some of the ways many of these things were accomplished at the Fifth International Congress of Pesticide Chemistry which I participated in at Kyoto, Japan. This conference utilized a combination of Symposia Presentations and a series of morning and afternoon poster sessions with each session being organized under a main and a subtopic. There were several days allotted to the Poster Sessions, but the posters for an individual subtopic were displayed only for one day and were attended by the author during either the morning or the afternoon. This allowed all the authors to view all the posters.


Several months prior to the conference. each author sent to the Main Topic Organizer a manuscript involving the information to be presented on the poster and also sent an abstract which was given to the Subtopic Organizer to help in preparing for the discussion period at the end of the formal session. I am enclosing a copy of a portion of the program and of the paper which I submitted. Where an invitation was a requirement for attendance, the author could submit a suggested title and give his area of expertise, and the Program Organizer could elect to extend an invitation to the potential participant. We could do something similar for our meeting in 1992. For example, I work primarily on the effect of adjuvants and environment on absorption, translocation, and phytotoxicity of herbicides. I would like to present a poster on the effects of environment on herbicide activity on perennial weeds in soybeans and cotton at the meeting in Australia. In order to be able to attend, I would have to be invited.

I fully realize that we are not setting out to completely copy some other organizations procedures, but often we can adapt ideas where they serve to help us accomplish our goals.

I am looking forward to learning of I further developments in the organization of

this First International Weed Control Congress.
