Weed Science Society of the Philippines

logo wssp 1The Weed Science Society of the Philippines (WSSP) was organized on September 6, 1968 by individuals who were interested in the study and control of weeds and who recognized the increasing problems posed by weeds in agricultural crops in the country.

Its formal proclamation as a scientific professional organization was made during the first national WSSP meeting on December 13, 1968 held at the Sulo Restaurant in Manila. On October 23, 1973, its incorporation as a non-stock, non-profit organization was approved by the Securities and Exchange Commission (SEC) of the Philippines. WSSP membership is over 300 from all over the country. There are some international members from 25 countries. The members are involved in individual and collective efforts in controlling weeds in agricultural crops, non-crop areas, pastures and rangelands, forests, and aquatic areas to make agriculture more productive, recreational areas cleaner and more attractive, and industrial sites and aquatic areas free of weeds. WSSP is an affiliate member of the Pest Management Council of the Philippines (PMCP), the Asian-Pacific Weed Science Society (APWSS), and the International Weed Science Society (IWSS). It also maintains close liaison with other crop protection organizations in the country, with other weed science organizations in the Asian-Pacific region and other parts of the world, and with other professional or scientific organizations having related interests.

The major objectives of WSSP are to: 1) encourage and promote the development of scientific knowledge concerning weeds and their control; 2) foster high standards of weed science education and research and encourage its acceptance as a field of training; 3) promote the publication and dissemination of knowledge gained on weeds and their control; 4) cooperate with other organizations that have similar or related objectives,; and 5) advise the national government, upon request, on matters of weed science and related areas of plant protection.

Any person, organization, or association in the Philippines and in other countries concerned with weeds and their control and shares genuine interest in the promotion of weed science is eligible for membership in the Society. Every member is entitled to vote, to hold office, attend or present papers during annual meetings, publish papers in office WSSP publications, and receive the Philippine Journal of Weed Science and the WSSP Newsletter free of charge and other pubications of the Society at reduced prices. There are four membership categories: Regular, Life, Sustaining, and Student members.

Eleven (11) members of the Board of Directors are elected annually by the members of the Society. The Directors elect among themselves the Officers and Chairmen of Standing Committees. The officers of the Board of Directors include: President, Vice-President, Secretary, Treasurer, Business Manager, and an Editor. They have a one-year term. Committees are organized to help run the activities of the Society. There are currently seven standing committees: Program, Membership, Election, Publication, Awards, Scholarship, and Funds for Weed Science. Three regional representatives (one each for Luzon, Visayas and Mindanao) are appointed by the Board of Directors to help carry out Society activities and facilitate faster communication among members from various parts of the country.

WSSP organizes and co-sponsors scientific meetings and conferences to discuss and evaluate recent advances in the field of weed science and plant protection in the country and internationally. Its annual conference and meeting is held every year during the first week of May in conjunction with the annual conference of the Pest Management Council of the Philippines, Inc. (PMCP).
WSSP was organizer and host to three conferences of the Asian-Pacific Weed Science Society: 1) the second APWSS conference held on June 16-20, 1969 at the International Rice Research Institute in Los Banos, Laguna, Philippines; 2) the ninth conference held on November 28-December 2, 1983 at the Philippine Plaza Hotel in Manila, Philippines; and 3) the 19th conference held on March 16-21, 2003 at the Philippine Plaza Hotel in Manila.
Through PMCP, WSSP was also involved in organizing and hosting of the International Congress of Plant Protection held in October, 1987 at the Philippine International Convention Center (PICC) and the Philippine Plaza Hotel.
