Film coating

Film coat thin layer

In thin layer coating, the main objective is to produce quality seeds, which ultimately leads to increased yield. Coating formulas with different chemical toxins in appropriate amounts for each seed improve germination to achieve a more uniform germination. In this method, there is no change in seed shape and it constitutes only 1-10% of the seed weight.
Advantages of film coating
1. Increasing the number of seedlings
2. Enhancing yield
3. Increasing seed germination
4. Uniform and better germination
5. Marking
6. Increasing marketability

Description

Film coating
Creating a thin coating around the seed is another accomplishment for seed coating technology, which uses pigments accompanied by water-soluble polymeric materials. Of the advantages of this method is frequent use of the formula during spraying and drying processes, which in turn causes a thin multi-layered coating to form on the seeds.

Favorable factors for seed treatment:
1. Adequate effect against pathogens
2. No poisoning effect in the plant
3. No negative effect on germination
4. Optimal storage
5. Cost-effectiveness

Organisms controlled by seed treatment:
1. Fungi, viruses and seed-borne bacteria
2. fungi and bacteria of soil and insects that damage the plant during the germination or seedling stage. The Vigor index shows how well a seed mass can withstand various environmental stresses. It is also an important parameter for measuring seed quality, which plays an important role in agricultural and horticultural production.
