What is AASCO?



The Association of American Seed Control Officials is an organization of seed regulatory officials from the United States and Canada. The Association was organized in 1949, from an outgrowth of regional meetings held in various parts of the United States. The members meet annually to discuss mutual concerns of seed law enforcement, to be updated on new developments in the seed industry, and to update the Recommended Uniform State Seed Law (RUSSL) which the organization developed and maintains as a "model" law for states and federal programs.

Seed Sampler Test & Certificate

Uniformity in seed sampling is important, and AASCO is providing training for seed samplers to help with that process. The AASCO Handbook on Seed Sampling and the Basic Seed Sampler Test/Certificate is a step in the right direction.
