Which item is a common seed-treatment application equipment type?

• A. Inline coaters
• B. Planters
• C. Harvesters
• D. Sprayers

Answer: (A)

In seed treatment, coating seeds with protective or beneficial materials is done with equipment designed to apply coatings uniformly as seeds move through a processing line. Inline coaters are built to handle a continuous flow of seed and apply coating material in a controlled, even layer. They offer precise control over how much coating is applied per seed and can run at high throughput, which is essential for commercial seed treatment operations. This setup also helps reduce dust and preserve seed viability while allowing different types of coatings (fungicides, insecticides, polymers, colorants) to be applied consistently.

Planters and harvesters are field equipment used for planting and harvesting crops, not for applying seed treatments in a processing line. Sprayers are used to apply chemicals to crops in the field, not to coat seeds during processing. So inline coaters are the equipment type most commonly associated with seed-treatment application.
