Why should you use certified seed?

Seed farmers know their business

Certified seed potato is always produced on specialist farms. They have passed the regulatory inspection process, and the growers are professionals in their field. Growing is specialised in areas and field sections best suited for seed potato. Seed potato packing plants must maintain a valid regulatory packing permit.

Certified seed is always officially inspected and approved

The quality of registered seed in seed potato cultivation has been verified by regulatory inspections. All the seed potato fields have been tested against cyst nematodes. Seed potato farms undergo one or two field inspections during the growing season in which the purity of the variety and disease status are verified. In addition, laboratory tests are carried out during winter on seed potato lots for bacterial ring rot and viruses. Storage inspections must not reveal soil, dry rot or blackleg, mechanical or physiological damage or potato scab over the allowable limits. Sorting size in the lots is also verified. Self-monitoring of the farms complements regulatory control.

Risk management and cost efficiency

Long-term cooperation between the buyer and seller helps to stabilise the demand and supply of seed potato. If seed are ordered too late, you may be left without high-quality seed, whereby the quality chain of potato production is broken even before planting. Buying the seed annually from a seed potato supplier removes any risk relating to seed care. Another advantage is the removal of storage and handling costs of seed produced on your own farm as well as increased and productive growing and storage space.

The seed potato chain helps to develop a better product

Seed potato producers are committed to developing their operations. Operators in the field participate in various development projects. Customer orientation is one of the commonly accepted goals.
