Explanation:
Detailed explanation-1: -Fruit and leaf drop at early stages can be prevented by the application of the plant hormone or plant growth regulator (PGR) Auxin (Indole-3-acetic acid or IAA). They also promote abscission of mature and older leaves.
Detailed explanation-2: -Auxins is a plant hormone that is known to inhibit both premature leaf and fruit fall.
Detailed explanation-3: -Spraying with Auxins can help to prevent leaf fall and fruit drop in a plant. This is because Auxins prevent the formation of a abscission layer which is formed before seperation of plant parts.
