Seed is not known to carry this fungus in trade. Urocystis cepulae teliospores have occasionally been found unattached to seed in seed lots, but seed transmission has not been proven. Seed conditioning should remove any associated fungal spores and physical purity testing should verify removal of any potential contaminate.
