The International Database on Commodity Tolerance (IDCT)


The objectives of the International Database on Commodity Tolerance (IDCT) are to gather and interpret the literature about commodity quality after phytosanitary irradiation treatment to aid stakeholders in Member States to identify the doses of radiation that are tolerated by different commodities including fresh fruits, vegetables and cut flowers in planning for commercial use of the technology. The information may also help users of the technology determine optimum methods of applying irradiation including pre- and post-treatment handling and if radiation may augment quality or prolong shelf life. It may furthermore be used to identify gaps and inconsistencies in knowledge that may be explored by researchers.

Important Note: For the best search results, please use the specific database search function at the left hand side of the page “Browse IDCT Database”.

IPCS is very grateful to Dr.Chen Ma for his generous contribution in reviewing the Chinese literature on phytosanitary irradiation and to Dr. Kikuchi Masahiro et al. for their valuable contribution.

Disclaimer: The International Database on Commodity Tolerance (IDCT​) is intended to provide access to scientific and other technical information which detail findings on dose tolerance required for phytosanitary irradiation of horticultural commodities. IDCT should be considered as a tool for first-cut analysis that interprets and summarizes existing information on commodity tolerance to radiation. The information on radiation doses is summarized in IDCT, even though some of the publications compiled are unreliable due to poor methodologies and lack of dosimetries. Therefore, it is the responsibility of the user to confirm the information and to verify it by way of the original publication and pilot testing as deemed necessary. Whilst every effort has been made to search all relevant publications, no assurance can be given that the reference search has been exhaustive. The IDCT database is not an authoritative source for nomenclature or taxonomy classification - please consult the relevant scientific literature for the most reliable information and the "International Code for the Nomenclature for Cultivated Plants" (ICNCP) for the latest information.
