Seed Testing

To reassure you that your potential Farm-Saved Seed is suitable for Processing, we offer a full range of seed testing services. These include Germination, Viability, Vigour, 1000 grain Weight, Admix, and various disease tests, all of which are optional.

Cereal Testing

Test Comment Results
Vitascope Low cost, it tells you whether the germ is alive or not. May not show up Pre-Harvest Glyphosate, or moderated drying damage 1-2 days
As Grown Germination The most accurate assessment of the seeds ability to produce normal seedlings under lab conditions 12-15 days
Rapid Seed Viability & Vigour A more sophisticated and accurate version of the Vitascope test, also giving a score for vigour 2-3 days
1000 grain Weight Seed is screened before weighing to enable calculation of optimum seed rates 1-2 days
Admix./Purity An assessment of seed purity, either weed or species 1-2 days

Seed can be sent direct to the Seed Laboratory in our Goldingham Contracts Freepost Seed Sample Bags for all the above seed tests.

ORGANIC Cereal Seed Samples should be tested for disease:-

Cereal Disease Tests if concerned about seed quality:

  • Barley Tests - Loose Smut, Leaf stripe, & Net blotch,
  • Wheat Tests - Bunt, Microdochium + Septoria,
  • Oat Tests – Loose Smut, Microdochium & Leaf Spot

Seed Test Price lists are sent out when anticipated seed processing is booked. We use independent Licensed Seed Laboratories that are the most cost-effective, appropriate, and reliable for the individual crop you wish to have tested.

The results are sent to Goldingham Contracts, so that we can discuss them with you, and then make an appropriate arrangement to clean and treat your seed when it is convenient for you.
