Synopsis (short abstract) Rubber is an important cash crop in a number of countries in Asia and the Pacific region. Current total global production of natural rubber is about 9 million tonnes. Over 90 percent of that amount is produced in Asia-Pacific. South American leaf blight (SALB) is a fungal disease of rubber trees. Up to now the disease has been restricted to South and Central America where it has inhibited natural rubber production on a commercial scale. So far, use of modern systemic fungicides and improved appl ication techniques have failed to prevent large scale losses and dieback of trees. Its potential to affect other regions rises with every transcontinental airline connection that directly links tropical regions. The need to develop quarantine measures against the disease is urgent. This publication is a compilation of four separate documents intended as a practical reference tool for national plant organizations, especially for plant quarantine officials, in rubber growing countries in Asia and the Pacific. It was prepared as a set of reference materials to improve phytosanitary measures and safeguard against the incursion of South American leaf blight of rubber into countries in the region, and is one of the many measures that the Asia and Pacific Plant Protection Commission has put in place to prevent SALB disease in the region.

    South American leaf blight (SALB) is caused by the fungus Microcyclus ulei (P. Henn) v. Arx and is the most destructive disease of rubber. It has been a major constraint in the production of rubber in South America. The disease could also cause great economic damage to the rubber growing countries of Asia and the Pacific if it were to be introduced into the area. This was recognized when establishing the Plant Protection Agreement for the Asia and Pacific region in 1956. When revising the Agreem ent in 1999 to bring it in line with the WTO Agreement on the Application of Sanitary and Phytosanitary Measures, the 1956 provisions relating to SALB were found to be inconsistent. After undertaking a pest risk analysis, this standard was developed to provide guidelines on preventing the entry, spread and establishment of SALB in the region. This standard was endorsed by the twenty-sixth session of the Asia and Pacific Plant Protection Commission (APPPC) held in New Delhi, India in August-Septe mber 2009. Regional standards for phytosanitary measures are part of the plant protection programme of the Commission's contracting parties to support regional harmonization and facilitate trade of commodities by member countries.

    South American leaf blight (SALB) is a fungal disease of rubber trees and poses a major threat to the region. Prevention of the introduction of SALB is of major concern to member countries of the Asia and Pacific Plant Protection Commission (APPPC) and is one of the priority areas in the work plan of the APPPC. In November 2011, the APPPC organized a regional workshop for development of a training programme and production of reference materials for protection against SALB. The reference material s include promotional materials to raise awareness of the dangers posed by the introduction of SALB in the region. They include a pamphlet, a booklet, posters, banners and PowerPoint presentations for training sessions for various audiences including the general public, extension and quarantine officers, pathologists and technical officers. The workshop also prepared operational guidelines to safeguard against the incursion of SALB in the region. This publication is a compilation of the above ma terials and is expected to enhance the capacity and capability of each country's readiness to detect, prevent and manage the introduction of SALB. Translation of this publication, or selected parts, is encouraged to maximize the potential benefits for countries in the region.

    This standard provides guidelines to help member countries develop and improve phytosanitary measures for the prevention, control and eradication of South American leaf blight of rubber (SALB) in the Asia-Pacific region. The guidelines cover five major areas dealing with: (i) prevention of the introduction of SALB into the region, (ii) development of contingency plans for eradication or control programmes in case of entry, (iii) development of training programmes including inspection, diagnostic and disinfection procedures, surveillance, eradication and control measures, and advocacy (iv) minimum resource requirements for national plant protection organizations to safeguard against the incursion of SALB and (v) establishment of national centralized bodies to coordinate the SALB programme, and cooperation among bodies within the region and with other regional and international organizations that deal with rubber. This standard was endorsed by the twenty-sixth session of the Asia and Pa cific Plant Protection Commission (APPPC) held in New Delhi, India in 2009. Regional standards for phytosanitary measures are developed and adopted by APPPC as part of the plant protection programme of the Commission's contracting parties to support regional harmonization and facilitate trade of commodities by member countries.
