Purity, Germination & TZ | Bulk Exams | Other Tests | Other Services

Purity, Germination & TZ

AOSA purity includes all-states noxious examination. ISTA purity includes ISTA certificate (Blue or Orange). Please consult our ISTA information before ordering ISTA tests. Samples requiring extra steps or those with high levels of impurities (other crops, weeds, multiple florets, inert materials) requiring more than 1 hour analyst time will be charged a prorated hourly charge based on extra time required. 10% discount on germination retests ordered January-June. ISTA TZ test requires double the amount of seeds.
