During July, August and September we work closely with the Northwestern and Midwestern Grass Seed Industry to assist in quickly testing the crop. Our staff is composed of four RST's and 15 other analysts experienced in purity and germination work. Check out our native species page for information on other grass species.
ISTA tests are also available.
The All-States Noxious Weed Examinations include all states except Hawaii. Submit a 250-gram sample for these tests. When we observe low germination due to ungerminated seeds, we check their viability using the tetrazolium test. We also identify fungal species and abnormalities to help explain the cause for lower viability. Tetrazolium Test Tetrazolium Test is a quick viability test completed within 24 to 48 hours.
