Best Practice

Please see below some guidelines for our cereal seed growers:

Every bag of seed is labelled with the reference number of the seed lot, as well as the kind of variety. Part of the crop inspection procedure is to verify the authenticity of the sown seed by looking at the label. Seed crops can be rejected if this is not possible.

Therefore, for each seed crop, growers must keep at least two labels from each seed lot sown. One label should be displayed in the field and the other kept at the farm office with the field name written on the back. We recommend that all the seed labels are kept.

Each seed crop must be separated from any other cereal crop by a physical barrier or by two meter isolation gap. This is to prevent cross-contamination between crops at harvesting. Seed crops sown closer than this will fair their inspection.

Drills and combines should always be cleaned out before starting on a different species and variety. Augers, either in the combine or for moving grain in and out of storage, are a particular source of contamination.

Grain trailers, dryers and storage bins also need thorough cleaning.

Many cases of accidental contamination of seed happen in storage. It is essential that seed in store is clearly labelled with the variety, field name or numbers and category of seed.

Excessive temperatures when drying will damage seed and lower its germination.

Crop Details
Each field has to be registered separately, even if some are the same variety and are sown with the same seed lot. However, it is possible to store the produce of such crops together after harvest. Before doing this, growers should always check with the merchant to make sure that the crops have passed at the same level.

Farm Assurance
It is a requirement that all seed growers are farm assured.
