Seed Coatings Imerys minerals improve seed homogeneity, integrity and seeding production
Seeds are coated for ease of handling, singulation, precision placement and the incorporation of beneficial chemicals or microbials. Coated seeds are accepted widely as a standard product for many crops.
Imerys minerals are used in seed encrusting and pelleting
- Color
- Lubrication
- Increase seed size / weight
- Addition of pesticides / inoculants
- Improve seed placement and germination rate = “Stand establishment”
- Vegetables, “forage”, cotton, tobacco, sugar beet
- Minerals used as pigments, pigment extender, resin extender
Imerys minerals are used in film coating or seed enhancement
- Color - all genetically modified seeds need to be colored for identification
- Lubrication
- Addition of pesticides / inoculants
- Minerals used as pigments, pigment extender, resin extender
Calcium Carbonate for seed coatings
- Low cost seed builder, increasing seed dimensions, easier to handle
- Achieves better seed to soil contact
- Less puddling of seed
- Penetrates stubble and thatch
Recommended Grades
- MicroWhite 100
- CP Filler
Diatomaceous Earth for seed coatings
- Biogenic amorphous silica, disks or drums; dependent on diatom species
- Rigid but porous structure
- Lower bulk density / high porosity than limestone
- Lower mass for same coating thickness
- Effective carrier or diluent ‘pre-mix’ for active ingredients
- Increases oxygen and water transport to seed after planting
Recommended Grades
-
Diafil 630
-
Celite 209
Expanded milled perlite for seed coatings
- Friable but porous structure
- Lower bulk density / high porosity than limestone
- Lower mass for same coating thickness
- Increases oxygen and water transport to seed after planting
Recommended grade:
- Harborlite 635
Synthetic Calcium Silicate for seed coatings
- Flow aid at very low addition rates
- Liquid pesticide carrier
- Carries hydrophobic components into hydrophilic formulation
Recommended grades:
- Micro Cel E
