Step 1: Understanding the Concept:
Seed treatment involves the application of biological or chemical formulations to seeds prior to planting to shield them from soil-borne pathogens and pests.
Step 3: Detailed Explanation:
Let us review the terminology:
1.
Seed priming: A hydration process where seeds are soaked to trigger pre-germination metabolic activity, then dried back before sowing.
2.
Seed conditioning: The mechanical cleaning, sizing, and grading of a seed lot.
3.
Seed seasoning: A storage or curing period to stabilize moisture and dormancy.
4.
Seed dressing: The direct coating of seeds with dry or liquid chemical formulations (fungicides, insecticides) to protect the seed and emerging seedling from soil-borne pests.
