seed coating

Seed coating has been listed as a key extension of agricultural technology projects. The seeds with pearlescent powder (seed colouring) can quickly absorb water and expand after sowing. With the gradual development of embryos in seeds and the continuous growth of seedlings, the effective ingredients contained in seed coating agent are slowly released and gradually absorbed into the body by seed seedlings, so as to achieve the purpose of controlling diseases and insect pests at seedling stage, promoting growth and development, and improving crop yield.

Product introduction

White pearl pigment can be used in stand-alone applications or combined with other pigment products to create exciting effects across various formulations.Colour luster pigments add not just colour but ready to use intense, vivid colour & shine.They surpass the effect from using the combination of dye or absorption pigments with pearl and provide far more formulation options.From matte effect to sparkle shining luster, there are particle size difference.


The Process of Seed Treatment 

The first thing to prepare is the slurry of mixed with pearl pigment powder, seeds, water and pelleting powder.The production process is as follows:

Step1: Put seeds and start to run the coater

Step2: Spray a little water

Step3: Add pelleting powder by slowly

Step4: Inject the slurry mixed with effect pigment powder

Step5: Increase speed of rotary disk

Step6: Do step3 and step4 above 10-15min

Step7: Add finishing powder and check coating seed size

Definition of Seed Treatment

In agriculture and horticulture, seed treatment or seed dressing is a chemical, typically antimicrobial or fungicidal, with which seeds are treated (or "dressed") prior to planting. Less frequently, insecticides are added. Seed treatments can be an environmentally more friendly way of using pesticides as the amounts used can be very small. It comprises priming, coating, pelleting, phytosanitary treatment, and microbial inoculation.

Advantages of Seed Treatment 

1. Seeds treated with pearl pigment can inhibit, control, or repel plant pathogens, insects, or other pests that attack seeds, seedlings, or plants.

2.Seed treated with effect pigment is aim to reduce inoculum levels and disease development from seedborne fungi that are present on or within seeds, without affecting the viability and emergence capacity of seed.

3.It is usual to add colour pearlescent pigment to make treated seed less attractive to birds if spilt and easier to see and clean up in the case of an accidental spillage.
