To be competitive in regional and international trade, Member States are required to demonstrate compliance with a number of well-established standards including those of plant health. As a result, a harmonized regional Plant Health Strategy is an imperative. The region must establish a coordinated strategic approach to plant health including contingency planning to ensure that measures are in place to combat disease outbreaks.

The establishment of CAHFSA as a regional body will facilitate a well organized and coordinated plant health system for the region aimed at increasing expansion in regional and extra regional trade and preventing phytosanitary vulnerability due to the risk of introducing pests and diseases.

Phytosanitary Resource

The phytosanitary resource page contains information intended to assist Member States in improving their Plant Health Systems. In addition to those that might be produced by CAHFSA, these resources include manuals, diagnostic protocols and training material developed by Regional and International Organizations involved in plant health such as the FAO, IPPC, CABI, IICA, CPHD and RPPOs. In some cases, the document may be downloaded for this website while in others the user will be redirected to external pages.  he IPPC Secretariat encourages contribution in any languages, from anyone in the world in the field of plant protection including IPPC contacting parties, Regional Plant Protection Organization (RPPOs) and other relevant organizations.


According to the World Trade Organization’s Agreement on Sanitary and Phytosanitary Measures (WTO-SPS), plant health measures must be technically justified and consistent with the risk presented. Technical justification of phytosanitary measures, in many cases, relies on accurate diagnostics. Diagnostic services are therefore essential to the fulfilment of obligations and responsibilities under the WTO-SPS agreement.

Plant Diagnostics Manual
The IPPC presents a guide for establishing a plant pest diagnostic laboratory. The resource aims at providing information on the establishment, operation and maintenance of a diagnostic laboratory and services in order to support national phytosanitary systems.

Diagnostic Protocols

Proper pest detection and pest identification are crucial for the appropriate application of phytosanitary measures. In particular, NPPO’s need proper diagnostic procedures for determination of pest status and pest reporting. The IPPC’s Technical Panel on Diagnostic Protocols (TPDP) develops diagnostic protocols (DPs) within the framework of ISPM 27:2006 and develops guidance on related issues.
