Seed coating

Encrustments

Even after processing, seeds of many important crops are naturally very small, misshapen or have wide size ranges, making it difficult to handle them in mechanised seeding equipment.

Germains encrustment techniques enable us to apply a minimum amount of filler materials and binders, whist still increasing the size of the seed, and filling out any irregular shapes and surfaces.

Pelleting

The area in which Germains first came to prominence, pelleting techniques have now been developed into complex seed coatings.

Pelleting is very useful for greatly increasing the size of very small or fine seeds to produce bigger, rounder, smoother and more uniformly-sized coated products, thus making them more suitable for precision planters that rely on mechanical principles (for example, filling the holes in cell-wheels or belts).

Pellets are also ideal carriers of fungicides and insecticide treatments. These can be accommodated in relatively large dose rates, and placed in discreet layers away from the seed. As this reduces the amount of fewer chemicals that need to be sprayed on fields, it also offers significant environmental advantages.

Pellets can also be constructed with desirable traits, such as ‘melting’ or splitting’, allowing light-sensitive seed to be quickly uncovered or to allow fast water and oxygen uptake.

Germains has developed a large range of pellet types for a wide range of species taking into account each species, germination and agronomic requirements as well as differing growing and climatic conditions.

Film-Coating

The use of seed coating polymers – or film-coating – consists of the application of a very thin water-permeable polymer-based coating layer on to seeds or pellets.

Film-coating polymers are available in a range of colours, coverage qualities, opacities and finish effects such as matt, shine and sparkle. As a result, they’re a highly effective way to colour seeds in order to check seed placement after sowing or for product identification.

However the main – and increasing  – use of film coating is in seed-applied crop protection treatments. Using film-coating polymers in high performance application equipment is a key factor in obtaining a dust-free, attractive product and a precise and accurate distribution of the agrochemical on the seeds.

Germains is widely acknowledged as the industry leader in the precision film coating markets. Our polymer range is adapted to answer all film-coating applications, combining cost effective application with the highest cosmetic finish.
