Testing Seed in Wyoming
The Wyoming Seed Analysis Laboratory is funded by the State of Wyoming, and administered by the University of Wyoming to serve the seed testing needs of farmers, private and public seed buyers, seedsmen, the Wyoming Crop Improvement Association, University of Wyoming seed researchers, and the Wyoming Department of Agriculture. The lab is equipped with modern testing equipment necessary to perform tests on all kinds of seeds, and is staffed with one Registered Seed Technologist and three permanent-staff lab assistants. The Rules for Testing Seeds by the Association of Official Seed Analysts (AOSA) are used as the basis for the purity analysis and germination tests performed in the seed lab.
Seed being sold in Wyoming must be labeled according to the Wyoming Seed Law and Regulations. The seed law requires all seed being sold to be labeled, and the label must include percentages of pure seed, other crop seed, weed seed, inert matter, and germination. A seed test will give the required values.
Testing saved seed will give the person using the seed a good understanding of the germination potential of his seed lot, and determine if the seed contains any problem weed seeds, including noxious weed seeds. It is advisable to check for problems before planting. If the seed lot has a low germination percentage, a good stand will not be achieved. If the seed lot has noxious weed seeds, or is contaminated with other crop and weed seeds, it may not be suitable for planting.
Seed Lab - FYI
- The Powell R and E Center has purchased new DNA testing equipment. We will start training on this and eventually be able to do in-house DNA tests on Palmer Amaranth.
- We would like to remind all that we have an Accelerated Aging chamber and can do Vigor tests on Beans or any other crop that you are concerned about aging problems.
- Jill Rice has moved on to retirement and we will miss her.
- Pure Harvest should be requiring new and more difficult passwords soon, we will keep you informed.
- Wyoming’s regulated weed seed list has been re-worded due to confusion of what to do if these seeds are found.
- Wisconsin and Washington State have added Amaranth species to their prohibited weed seed list, Washington’s doesn’t go into effect until Oct. 11, 2018. So if you ask for an all states or western noxious exam and Pigweed is found, it will be labeled a prohibited noxious weed seed.
- We will probably be offering a DNA test for Pigweed, the cost is around $10 per seed, $50 minimum. We will send those out to either Illinois or Wisconsin for that test, a 2 week turnaround time is expected.
- Pam Bridgeman and Jill Rice have both passed their certification exams. Pam in purity and Jill in Germination. Pam will become an RST and CSA.
