Pre-treatment: Seed should be treated with Carboxin or a similar compound to prevent head smut (Ustilago bullata) in subsequent seed crops.
Establishment: Seed ripens in mid to late July in the Pullman area, but earlier in the warmer, drier areas of Washington. It is collected when the inflorescence begins to dry and the seed is in the soft to hard dough stage but before it shatters from the inflorescence. Seed can be stripped from the inflorescence or the inflorescence can be clipped from the plant. Harvested seed is stored in paper bags at room temperature until cleaned.
