The International Rules for Seed Testing are ISTA primary tool to promote uniformity in the seed testing industry. Featuring 19 sections, the International Rules for Seed Testing have definitions and standardised methods to be used in sampling, testing seed lot quality and reporting results for international trade. The ISTA Rules are voted, amended and approved annually at the Ordinary General Meeting after considering the Technical Committees recommendations.

Seed Science and Technology (SST) is an international journal, featuring original papers and articles on seed quality and physiology related to seed production, harvest, processing, sampling, storage, genetic conservation, habitat regeneration, distribution and testing. A journal that meets the needs of researchers, advisers and all those involved in the improvement and technical control of seed quality. 

Seed Testing International (STI) is ISTA News Bulletin, distributed to over 1700 subscribers worldwide. STI includes reports from ISTA President, Technical Committees, and Secretariat. It also includes articles, addressing various aspects, concerning seed testing in general.

This is the reason why STI is read by parties, interested in seeds, including ISTA Members and their laboratory personnel in more than 70 countries/distinct economies.
