HOW SEED TREATMENTS ARE APPLIED? • • Seed treatment is a term that describes both products and processes. Processes range from basic dressing to coating and pelleting. In all cases, the basis of good application techniques is to deliver the product to the seed at the correct dose and as uniformly as possible from seed to seed. Seed Dressing: The most common method of seed treatment. The seed is either dressed with a dry formulation or wet treated with a slurry or liquid formulation. Dressings are applied both on-farm or in specialized seed treatment facilities. Seed Coating: A special binder is used with a formulation to enhance adherence to the seed and begin to impact seed size and shape. Coatings require advanced treatment application technology. Seed Pelleting: The most sophisticated seed treatment technology, resulting in changing the physical shape of a seed to enhance plantability and handling. Pelleting requires specialized application machinery and techniques and is the most expensive of the applications. | Vigyan Ashram | INDUSA PTI | 4
