Mid-West Seed Services, Inc. is now offering the Corn Referee Test (CRT) as a more comprehensive procedure to evaluate seed quality within today’s rapidly evolving corn hybrids, traits, fungicide and seed-applied insecticide environment.  A continually changing list of hybrids, the need for quick decision making information and an increasing expectation for seed quality requires a stepwise approach to assess seed quality.  

Choose a CRT as a matter of routine or when a corn contract has an “apparent” quality issue. We recommend testing an 800-seed warm germination and 400-seed tray cold or saturated cold, as appropriate.

Sampling is always a critical step and especially when an “apparent” seed quality issues exists. More attention to proper sampling, composite sample mixing and reduction to submitted sample size is required to assure a representative sample.  MWSS has developed a corn sampling fact sheet for your review for proper sampling procedures.
